Our November general meeting welcomed
regulars Rockian Trading and Osborn speakers.
Ian has kindly provided a detailed description
of the tracks he will present on the night.
We are looking forward to presenting some
new "audiophile tracks" to members of the
Melbourne Audio Club in the Willis Room. As
usual Beverley's bazaar will have a selection of
recordings for sale to MAC members at special
prices. Some particular bargains will continue
to be offered from the Rockian Trading
catalogue.
Once again we thank Greg and Yvonne Osborn
for providing the appropriate audio equipment
for the occasion.
The following is a list of recordings I would like
to share with members in the time available:
ATMA Classique ACD2 2831 - Calcutta 1789 /
Notturna, Christopher Palameta (East meets
West).
A musical program from a concert enjoyed by
the families and friends of the British East
India Company. Works by Johann Christian
Bach (alive at the time), George Frederic
Handel, Henry Purcell and Carl Friedrich Abel
(recently deceased at the time and labeled "The
Ancient Masters"). Also included are two
works by Irish born William Hamilton Bird,
who lived in Calcutta, now Kolkata, for two
decades. He transcribed many classical Indian
pieces to Western tablature for ensembles
including Sitar and Tablas. The Beatles weren't
the first to incorporate Indian elements into
their music. Sorry George, but I bet you knew
anyway!
ATMA Classique ACD2 2454 - Sibelius 3 & 4 /
Orchestre Metropolitain de Montreal, Yannick
Nezet-Seguin
This fine recording of Sibelius Symphonies
makes for a wonderful audio concert. A
composer greatly influenced by the classical
and romantic composers who preceded him
and not totally committed to the impressionists
who were his contemporaries. Totally
involving!
ATMA Classique ACD2 2803 - Chopin
Recital / Janina Fialkowska
A selection of 12 Chopin Polonaises, Nocturnes,
Preludes and more from this 19th century pop
star, some melodies that remain popular today.
These recordings were engineered and
mastered by Anne-Marie Sylvestre who
continues to uphold ATMA Classique's
reputation for outstanding productions.
Fresh! from Reference Recordings - FR-748 -
Reencuentros / Cecilia Duarte and Latin guitar,
bass and percussion ensemble.
Fresh! from Reference Recordings - FR-750 -
Le Dolce Sirene / Bach Aria Soloists.
A soprano, violinist, cellist and organist/
harpsichordist present works by Monteverdi,
Handel, Mendelssohn, JS Bach and McDowall.
Fresh! from Reference Recordings - FR-
751SACD, (3 Hybrid SACD Box - 5.0 & Stereo
SACD + Stereo CD) The Compete Beethoven
Piano Concertos / Garrick Ohlsson piano,
Grand Teton Music Festival Orchestra, Sir
Donald Runnicles conductor.
We could hold a complete MAC meeting to
audition and evaluate this collection. Ohlsson
has played each of these concertos at least 100
times and conductor Runnicles is equally
experienced. In the enclosed booklet the
recording engineer provides us with an
explanation of his choice of microphone and set
-up. I recommend visiting the Abbey Road
Institute London web site for information on
the Decca Tree microphone set-up. At the
bottom of the blog tab click Recording
Techniques. Scroll down that page past the
Dolby Atmos link to The Decca Tree: The
secrets behind the legendary recording
technique. It's all in there.
Fresh! from Reference Recordings - FR-753 -
Schubert by Candlelight Live in Madrid /
Sergei Kvitko, piano 13 works captured live in
Madrid
Reference Recordings - RR-151 - Spanish
Impressions / Hermitage Piano Trio
Three passionate virtuoso musicians breathe
fire into this flamenco influenced program.
After years of working together the Hermitage
Piano Trio have gained a reputation of quality
ensemble work and are often praised by critics
for their "unity of sound." Their previous
recording for Reference Recordings release (RR
-147) "Rachmaninoff" was nominated for two
Grammy Awards. Both Hermitage Trio
recordings have been recorded and mastered by
Sean Martin, son of Keith O. Johnson and
Marcia Martin, founding partners in Reference
Recordings. A new generation taking over.
Thank you for your patience with these fine
classical recordings.
Now for some of the
amazing popular/rock re-masters we have
received this year. First up more Eagles
recordings.
Mobile Fidelity - UDSACD 2231 - On The
Border / Eagles
I remember this 1974 release primarily for the
first track, "Already Gone." The Country-Rock
cover band I was in at the time included this
song in its song list and I played it at least twice
a week for ages.
Mobile Fidelity - UDSACD 2233 - Hotel
California / Eagles
More has been written about this album,
particularly the title track, than almost any
recording in history. And, it deserves all of the
attention. The title track could easily be the
subject for a PHD thesis or more. For a start it
contains motifs and themes that could produce
at least four songs, and every piece of the song
is perfectly placed and executed. The vocal
harmonies are exceptional and the guitar parts
are melodious and the harmony solos,
particularly at the end of the song, are equaled
only by some guitar work performed by Steely
Dan session players. Listening to this
recording is also a pleasure without the
distraction of a video. Sadly this album,
absolutely full of great songs, was the best the
Eagle could do in the studio, and some believe
it should have been their last album.
Mobile Fidelity - UDSACD 2234 - The Long
Run / Eagles
"Heartache Tonight" from this album reached
No1 on the singles chart and won a Grammy
Award. Planned as a double LP the band
struggled to record the ten songs that made it
to studio. Worn out from touring with the
Hotel California shows, and the personal
disagreements during the making of this
recording lead to the Eagles breaking up. Until,
after fourteen years, The Hell Freezes Over
DVD and CD were made and released in 1994.
SHOW ONLY
Mobile Fidelity - UDSACD 2251 - Thriller /
Michael Jackson
In 1983 this album was listed as "The bestselling
of all time."
Here Mobile Fidelity have mastered an album
for "listening," not like the original, mastered
for "dancing." And they have done a brilliant
job. Thriller is a masterpiece in production by
Jackson, who learnt the trade by "ghosting" the
Jackson 5 producer Berry Gordy. Gordy built
the label Motown from the ground up as a
songwriter, producer and entrepreneur.
Michael was an enthusiastic student of the very
best producer.
(The Berry Gordy's story is an interesting read.)
Michael hired the musicians he knew could
play what he wanted. Most of the tracks are
played by the personnel from Toto including
the Porcaro brothers and Steve Lukather. He
hired Eddie Van Halen to solo on "Beat It" and
sings a duet with Paul McCartney on "This Girl
is Mine."
Mobile Fidelity - UDSACD 2224 -
Unplugged / Eric Clapton
Recorded live for the MTV Unplugged TV series
this is the soundtrack produced for a small
audience in a TV studio in Windsor, England.
Hard-core blues critics derided it as "Blues for
the Yuppies," but I find this recording, devoid
of the distracting video, very interesting. The
lack of guitar and vocal effects exposes
Clapton's raw talent in spades. I play this to
track fourteen and am disappointed it has
finished.
Mobile Fidelity - UDSACD 2217 - There Goes
Rhymin' Simon / Paul Simon
Track 1, "Kodakchrome" and track 10. "Loves
Me Like a Rock" were both big hits of this ten
track album of intriguing gentle songs. It
confirmed once more that Paul Simon as a
notable US songwriter. Every track is a gem.
Mobile Fidelity - UDSACD 2241 - Excitable
Boy / Warren Zevon
"Werewolves of London" is the big hit from this
strange album. The title, "Excitable Boy" is a
euphemism for a psychopathic teenage
murderer. "Werewolves" and "Lawyers Guns
and Money" are really the only tracks I
admire.
Mobile Fidelity - UDSACD 2085 - Kind of
Blue / Miles Davis
This recording has been pressed again as a CD
and a 45rpm Box set.
One of the advantages of using DSD archives is
you can cut a new pressing for LP replication or
down-sample to Hybrid SACD with no
discernable losses. Kind of Blue is one of those
gems, pick a track, any track, they are all
masterpieces.
Until now we haven't received any new jazz
titles this year. The scheduled Miles Davis
recording, "Seven Steps to Heaven" has not
arrived yet. Frustrating for us and all Jazz fans.

Lorantz Audio Services |
Monthly meetings of the MAC in the Willis
Room commonly see me leave the venue at the
end of the night with three emotions. First, I am
appreciative of the time and effort put into the
demonstration by the presenter, and am
reminded again of the devotion so many of
them have to our hobby. Second, in almost all
cases I'm happy that I've learnt something from
the demonstration, be it a new piece of music
I'd not heard before, insight into a particular
musical genre that I have a growing interest in,
or something about the technical aspects of the
equipment on display. Third, perhaps as a
combination of the first two sentiments, I often
come away uplifted by what I've learnt and
heard - and this of course is complemented by
catching up with old friends from the club and
chewing the cud about what had transpired
since the last meeting.
The October demonstration by Michail
Barabasz, from Lorantz Audio Services in
Dandenong (Melbourne), vouchsafed the first
and second emotions but not the third.
Michail's commitment over decades and
decades to the esoteric art of making
loudspeaker drive units was unmistakable. And
there is no doubt that every person in the
audience learnt a great deal about how
electrodynamic drive units are made and the
compromises that have to be balanced to
achieve the desired outcome. More on this later.
But it was the third emotion of my list that was
missing at the end of the evening. Rather than
being uplifted, I left slightly
saddened (and angry).
Again, more on this later.
Over many highly detailed
PowerPoint slides, Michail
outlined his experience in
the Australian loudspeaker
industry and how he makes
his electrodynamic drive
units. He pointed out that
he and his wife Hazel
established Lorantz Audio
Services in 1976, following
the closure in 1974 of
Plessey Rola, the well-known local
manufacturer and importer of loudspeaker
drive units that had factories in Richmond
(Victoria) and Willawood (NSW). Some older
history to provide a context: the
radiomuseum.org webpage says that in 1965
Plessey Pacific, a subsidiary of the UK-based
Plessey group, acquired Rola Holdings and its
two subsidiaries, Rola Company (Australia)
and Rola Co. (NZ). The former continued
trading as a subsidiary of Plessey Pacific until
1969, when it became Plessey Rola Pty Ltd.
Existing Rola products continued to be
marketed under the Rola name, and new
products under the Plessey brand. This
arrangement continued until 1974, when local
manufacture ceased. Why it came to an end is a
topic I come back to later in this review. It was
just after this that Michail and Hazel
established Lorantz Audio Services, using
equipment bought from the old Plessey Rola
plant.
I have a distant memory of buying a pair of
6"x9" Plessey Rola speakers, perhaps in 1974 or
so, to replace the non-functioning ones in the
stereo system I had in my bedroom at the time
(complete with ceramic cartridge with a needle
that you could turn over to play 78s; my god,
what must it have done to the LPs I was then
just starting to buy?). I listened through them
to the first broadcast of the radical new ABC
station 2JJ, in January 1975 on the AM band.
The presenter was the incomparable Holger
Brockmann and the first track played was,
infamously, Skyhook's You just like me 'cos I'm
good in bed. The station could get away with
such a moral outrage only because 2JJ (quickly
known as 'Double J') was a government-funded
station operating under the umbrella of the
ABC and having the specific mission of catering
for a younger audience that the ABC hitherto
had ignored, but wished to attract and retain as
they grew older. The station was not bound by
the censorship codes or owner-applied moral
framework that applied to commercial radio
stations such as 2SM.
Interestingly enough, 2SM was owned by the
Catholic Church in Sydney and its call sign was
named in honour of St Marks Catholic Church
in Drummoyne, from which it made its first
broadcast, in 1931. The station was to have a
call sign of 2CC, but the church wanted 2CB
("Christian Broadcaster"), and after
negotiations with the PMG settled for 2SM ("St
Marks"). You can imagine the morally steadfast
owners of 2SM were catatonic at the lyrics and
moral implications of broadcasting You just like
me 'cos I'm good in bed. After all, they had
earlier banned the song Itsy bitsy teeny weeny
yellow polka dot bikini, as well as the words
'rape' and 'pregnant' from their news services
(McCarty, no date). In August 1980, 2JJ
switched to the FM band. Again its first song
was one banned on commercial radio, Gay
Guys, by The Dugites from Western Australia.
Oh - those were the days!
Back to Michail and Lorantz. While at Plessey
Rola, Michail was responsible for the design of
a great many types of drive unit, including the
C60, C80, C100, C100X, PE800, PE 1000 and
PE1200 models. Today, Lorantz offers the
supply and manufacture of drive units and
complete loudspeaker systems, including for
public address systems, theatre systems, guitar
amps, including for bass guitars, and hi-fi setups
(https://www.lorantz.com.au/productcategory/
loudspeakers/). A very wide range of
cone electrodynamic drive units are made in the
factory in Dandenong, including units up to 18"
in diameter. The 18" bass driver must be a
terrifying thing, as the Lorantz webpage states
it has a program rating of 2000 watts, a peak
cone excursion of 9.5 mm but can withstand
excursions up to 21 mm before damage. In the
old imperial units, that's nearly an inch! This
behemoth costs only $420, which must be one
of the greatest audiophile bargains on Earth.
The firm also distributes imported horn
compression drivers and horn flares. This must
be welcome information for the DIY brigade
among our members who want to experiment
with horn-loaded systems, but I'm sure
hitherto was not aware of this local and
knowledgeable source of components and
advice.
For presentation purposes, Michail brought
along a Lorantz 12" 800-watt bass-mid drive
unit, the AC317V-B2S-8. It has a 3" voice coli
and high-temperate -rated components such as
spider and voice-coil former. Over the night he
went on to describe how the unit was
constructed: how the cones were hand-made
from a mix of flax and eucalyptus pulp that he
himself mixes and moulds into the required
shape; how the voice coils are wound and the
magnets magnetised using devices that would
not look out of place in Fritz Lang's 1927
Metropolis; how the spiders are formed from
Kevlar and resin, etc. Short of him going into a
forest with a chainsaw to actually cut down the
gum tree that would be processed into pulp, I
can't see a more 'hands on' approach to speaker
manufacture is possible.
So, what did I learn from Michail's
presentation? Many things, but four stand out.
First, that of all the criteria buyers want met
when ordering speakers - price, power
handling, efficiency/sensitivity, maximum SPL,
frequency range, distortion, reliability etc -
two, maybe three, were paramount: price,
power handling, and (especially for units
destined for motor vehicle) reliability. Least
important was distortion, at least for the PA
market.
Second, that the specifications published for
loudspeaker drive units almost always refer to
small-signal inputs of about 1watt or so. Of
course the speaker performs well under these
conditions. It is working in the most linear part
of its response. But the published
specifications are totally misleading when it
comes to how the speaker will perform when
it's being fed 200 watts or so, when all sorts of
non-linearities become manifest as cones, voice
coils, spiders and edge suspensions are forced
to move further and further away from their
equilibrium position and everything gets hotter
and hotter.
Third, the remarkable precision that goes into
making good electrodynamic speakers. The
clearance between the voice coil and the
magnet of Lorantz drive units is typically 15
thou, or 0.3 mm. That's about the same as the
valve clearances in an internal-combustion
engines (I know: I recently adjusted the tappets
on my ageing Subaru wagon).
Fourth, that Lorantz is almost alone in
manufacturing loudspeaker drive units in
Australia (as opposed to assembling imported
drive units into loudspeaker boxes). This was
the cause of my sadness (and anger) when
departing the Willis Room. Michail's
presentation brought home to me how a onceproud
Australian manufacturing base has been
destroyed over the past 50+ years,
commencing in the mid-1970s and rapidly
gathering pace since the 1980s, to the point
where almost nothing but a few isolated
remnants is left in 2023.
Michail pointed out that a major factor in
Plessey Rola decision to leave the business of
manufacturing loudspeaker drive units in
Australia in 1974 was the withdrawal of
protection for the Australian automotive
industry, which until then had been protected
behind very high tariff walls and had accounted
for a substantial part of the company's business
(e.g. via car radio speakers). There were very
sound reasons for post-war governments of
both political persuasions to retain the tariffs
and other protection mechanisms introduced
earlier in the century: to protect local
industries against the (also subsidised)
products of foreign producers; to protect those
industries against the avaricious and predatory
antics of importers; to provide an industrial
working environment that would give the local
working man and his family an honest and
liveable wage, as well as a reliable job; to
produce the domestic goods required by a longsuffering
population that had just come out of
the most destructive war the world had ever
seen; to generate a more balanced economy
with a strong emphasis on skills-based
manufacturing rather than merely on the
export of simple agricultural products such as
wool and wheat; to build-up local industries as
part of a stronger and more resilient national
defence should a world war ever break out
again (Bell 1993).
In the years running up to the closure of the
Plessey Rola plant, in 1966, for example, the
Menzies government increased tariffs for
completely built-up imported cars from 35% to
45%, which Conley (2022) noted made the
Australian car industry one of the most
protected in the world. Tariffs were increased a
further three times during the 1970s. The result
of these and earlier tariff decisions by a variety
of governments in the post-war period was a
burgeoning motor-vehicle manufacturing
industry, which employed huge numbers of
people in highly skilled trades and required
large and on-going inputs of locally made
components (such as speakers for car radios).
In 1964, as an example, GMH made 150,000
EH-model Holdens with 100% local content
(Conley 2022). In 1973, the Whitlam
government applied an across-the-board tariff
cut to 25%, but returned it to 45% the next year
(Owens 1995). The Australian-made share of
the motor-vehicle market fell from 84% in 1966
to 68% in 1973. The writing was on the wall,
and Plessey Rola responded by soon ceasing
local manufacture.
Let's look at some of the broader facts
pertaining to the decline of our manufacturing
base and the foundation of my sadness at the
end of the evening. In 1962-63, manufacturing
accounted for 26% of Australia's GDP
(Productivity Commission 2003). In 2001-02
it accounted for 13%. In 2021 it was a pathetic
6%. In terms of sector outputs, the 6% of the
economy that manufacturing currently
accounts for is overwhelmed by mining, at 15%,
and is exceeded also by the financial sector, at
8%, and by that curse of the Australian
economy, house construction, at 7% (Reserve
Bank of Australia 2023). Manufacturing
currently accounts for a piddling 7% of our
exports. In contrast, mining accounts for 63%
and agricultural products 11%.
And we employ fewer and fewer people in
manufacturing each year. In the immediate
post-war decades, manufacturing accounted for
nearly 30% of the Australian workforce; it's
currently less than 10% (Bureau of
Infrastructure and Transport Research
Economics 2006). In place of a strong
manufacturing base, we have an economy
based on the export of unprocessed red rocks
(iron ore), climate-destroying black rocks
(coal) and the making of houses and the
pouring of coffee and the cutting of hair for
each other.
All this has taken place in a country that once
designed and built the stupendous 36 Class
steam locomotive, and that in 1943, during the
height of World War 2, and even earlier the
magnificent Victorian S Class express
locomotive, in 1928. The same country that,
never having built a front-line combat aircraft,
designed and mass produced the CAC
Boomerang fighter within 6 months of
receiving RAAF approval in 1942, in response
to the war with Japan. Then built hundreds of
twin-engined DAP Beaufighters from 1944,
planes that were the scourge of Japanese forces
during the long and bitter Pacific campaign.
The same country that went on to build, de
novo, and improve the best-known Cold War
jet fighter, the North American/CAC Sabre in
the 1950s, followed by local construction of the
supersonic Dassault Mirage III in the 1960s.
That once was at the forefront of rocket and
radar design. That in the 1950s and 1960s
made or assembled a myriad of motor vehicles,
from Holdens to Fords to Valiants to
Mitsubishis all made here, to Vauxhalls and
Wolseleys and Morrises and Vanguards and
even to MGBs and Land Rovers imported in
parts from from the UK and locally assembled,
to the local assembly of Dodges and Chevrolets
from the USA, even of Peugeots and NSUs from
Europe. We even assembled Mercedes-Benz
motor vehicles, apparently to a standard
indistinguishable from the ones imported
directly from Germany (Farmer 2022). Where
you could buy Australian-made tools, such as
Sidchromes ("Y canna hand a man a grander
spanner"), that didn't break the first time you
put any force on them.
In the words of that great Australian novelist,
Xavier Herbert, Poor Fellow My Country. Or,
as Donald Horne noted in 1964, with nowforgotten
irony, that we are The Lucky
Country.
Thanks heartily to Michail for a fascinating, if
sobering, presentation last month and his
support for the feelings discussed in this
summary.

Members Request Night |
The August monthly meeting reverted to a
members' request night when the scheduled
presenter withdrew at the last moment. As is
standard with such nights, members put their
names into bins marked classical, jazz,
kaleidoscope or rock/pop and Dave Polanski
randomly drew names from each category in
turn. The selections had to be shorter than 5
minutes and were to be introduced with a brief
statement as to why that particular piece of
music was selected by the member.
The Gear
We had two sets of equipment on the night.
The first, provided by Jonathon, was based on
his beloved Quicksilver valve monoblock
amplifiers, fed by a Positive Vibrations valvebased
combined pre-amplifier and phonostage,
and feeding into a pair of DALI Ikon 6 floorstanding
speakers.
Jonathon explaining the gear
The Mike-Sanders designed Quicksilvers were
smaller than I had anticipated, and lovely little
things they were. They date from the early
1980s and use the now-discontinued 8417
power valve (one pair per side) for a claimed 60
watts per channel output. The 8417 is a powerbeam
pentode introduced by Westinghouse in
1963 and designed specifically for high performance audio amplification.
https://www.radiomuseum.org/tubes/tube_8417.html
Quicksilver Audio is still in operation and its
current catalogue lists five power amplifiers:
three monoblocks, one integrated and one headphone amplifier.
http://quicksilveraudio.com/amplifiers/
Quicksilver has long had an outstanding
reputation among audiophiles, and I was
amazed at how well priced the current models
were (well, at least in US$).
Quiksilver 8417 Power Amp
The pre-amplifier was a Trevor Lees invention,
designed and built by Rick Powell in
Melbourne. It is based on eight 12AX7 valves,
six of which run the phonostage.
Trevor Lees Pre Amp
Pre Amp Power Supply
The DALI speakers date from
the mid-2000s. Each tall,
narrow cabinet uses two 6.5"
woofers and a unique hybrid
tweeter consisting of a cloth
dome unit that runs from 3
kHz to 20 kHz and a ribbon
unit that runs from 14 kHz to
30 kHz. The reviewer in
Stereophile liked them in
2006 but commented that "the Ikon 6 does not like to be played too loud when playing complex recordings".
https://www.stereophile.com/floorloudspeakers/706dali/index.html
One point of interest:
Jonathon noted that Mike
Sanders recommends using short speaker cables
where possible and long interconnects where
necessary to join everything up, in opposition to
the more common practice of using long speaker
cables and short interconnects. This
is the way Jonathon set up his gear for the night.
The second system was provided by Moggie
and was based on his four-channel QUAD 405
power amplifier (yes, a quad QUAD!). Two of the
four channels (100 watts each) came from a
custom-built kit and two were original QUADs.
We don't know whether the latter were 405-1
from 1975 on or the latter 405-2 from 1982 on.
Chris explaining his gear
Nevertheless, all four channels were the trusty
current-dumper design invented by Peter
Walker in 1975. Current-dumping was/is an
ingenious approach to amplifier design, based
not so much on negative feedback as on
careful feed forward error correction, as
described for the non-expert by Gordon J
King in an article back in 1976 in Hi-Fi News.
https://www.petervis.com/hi-fi-info/quad-405-current-dumping/quad-405-currentdumping.html
The design won Peter Walker The Queen's Award for Technological Achievement in 1978.
Current-dumping has been used in almost all
QUAD amplifiers since its introduction in
1975 in the 405, including in the gorgeous
little 306 designed specifically for the thennew
ESL 63 speakers, the bigger and more
modern 606 and the most recent Artera. The
original article by Peter Walker, published in
Wireless World, that described the approach
is only three pages long and remains available
at the webpage of the Belgium-based QUADspecialist,
DADA Electronics
https://www.dadaelectronics.eu/uploads/downloads/05_Other-Quad-Documents/Current-Dumping-explained-by-Peter-Walker-1975.pdf
The general consensus is that currentdumping
amplifiers have high efficiency, are
of moderate cost and are neutral sounding, if
not quite as transparent as most other solidstate
designs. They were designed to power
QUAD's electrostatic speakers, which at the
time (e.g. for the ESL 63) could barely handle
50 watts without arcing, hence the 50 watts
per channel output of the 306. The 405 was
more powerful, as was the much later 606.
Thus there was at the time no need for an
amplifier that caused the street lights to dim
every time it was turned on; indeed, such a
high-powered amplifier would probably spell a
nasty, smoking end for the electrostatic
speakers of the day.
Moggie also provided a Hafler DH101 kit preamplifier
(dating from the late 1970s, with tone controls)
[Ed. The DH101 also has a heavily modified
audio path with mostly DC path or PP caps]
and a Denon DVD-2900 silver-disc player that
was used for most of the night. The Denon was
an up-market device in its day [Ed. 2003],
featuring a powerful DSD decoder (32 bit 192
kHz, six-channel SACD compatible audio DAC)
and Burr Brown 24 bit 192 kHz output DACs.
Alas it decided enough-was-enough towards
the end of the night and decided not to read
any discs. Maybe it didn't like Track 13,
Horowitz playing a Chopin nocturne, or maybe
it was a superstitious and pulled up stumps
precisely because it was asked to play Track 13.
Not to be beaten, Moggie went to his car for a
replacement, a HD-XE1-KY Toshiba HD-DVD
player, which sufficed for the rest of the night.

in and now even plays CD-Rs, before it didn't.

16. Sergei Prokofiev, "Dance of the knights", from Romeo & Juliet
17. Johann Strauss Sr, "Redetzky march".
The sound
First impressions are important, and my
initial response to the first track of the
evening was "I could live with this system all
day and not get bored on the one hand or
overwhelmed by the bloody thing on the
other". Was it the valve amplification that
made it so agreeable? Maybe, as what I heard
had coherence and fluidity, a detailed
midrange and a slightly soft bass, many of the
characteristics of valve amps. In almost every
case where we have had a valve amplifier and
a solid-state amplifier playing on the same
night, I've preferred the sound of the
thermionic one, mainly on the basis of its
soundstage, midrange and undefinable
'enjoyment' factor. But things changed hardly
at all when the QUADs and the Hafler
replaced the Quicksilvers and the Positive
Vibrations: the sound was still delightfully
unfatiguing and unforced, but not bland or
boring. So, in this comparison, either set-up
would do me fine. And remember that both
sets of amplification were at least 30 years old
- who says we always need to go out and buy
the most modern (and often highly price
inflated) gear?
As the night went on, I formed three more
conclusions. First, the two systems showed
clearly the different origins of the 17 tracks.
Some, for better or for worse, were audiophile
grade whereas others were technically flawed.
My choice of the Rodriguez, for example, was
marred by awful tape hiss and constricted
dynamics - but as always with great music,
that technical consideration mattered little
when placed in the context of the underlying
quality of the song and its delivery. The vast
difference in sound quality (and by that I mean
not only technical quality, but studio dynamics
or lack of etc.) contrasted greatly with what we
usually hear at monthly meetings, when the
tracks are often chosen by the presenter
primarily on the basis of their audiophile
credentials not their wider musical value or
interest.
Second, the soundstage varied all over the
place from selection to selection. Soundstage is
vitally important to me, far more important
than the ability of a system to go into abyssal
depths of the bass or stratospheric highs for the
treble. Some tracks had an astonishing width
and depth: Martin's "Blind Willy" was the
obvious example, with the sound appearing to
emanate from metres to the left and right of the
two speakers.
Third, I wondered whether the treble was a bit
exposed? Since the silver-disc player and
speakers were constant across the two systems,
the fault must lie in one of three places: (i)
where I was sitting, (2) the room, or (3) the
speakers. To test the first hypothesis, I moved
from the front row to the rear row, and the
slightly exposed treble remained. I found it
particularly exposed on Tracks 8, 13 and 17. So
we can rule out my seating position as the main
cause.
The second explanation was entirely possible:
the DALIs were being asked to do things that
would never be expected of a small pair of floor
-standing speakers, in a big room such as the
Willis Room with the acoustic delicacy of an
empty 44-gallon drum. Maybe in a smaller
setting, a domestic lounge room with carpets
and soft furnishings etc, with less oomph on
the volume knob, the treble would be tamed.
As the Stereophile reviewer noted, the DALIs
don't like to be played too loud when given
complex recordings.
Or, third, was it the peculiar type of tweeter
used in the Ikon 6s? Robert Reiner's review in
Stereophile made no mention of an
overbearing treble; indeed he described the
highs as "delicate". Nor did a positive review
in Hi-Fi News
https://www.hifinews.com/content/daliikon-6-mk2-%C2%A31199
A review in the less exalted What Hi Fi said the treble was "sparkling"
https://www.whathifi.com/dali/ikon-6/review
Some consumer feedback on the web has
described the speakers as a bit lean, possibly
bright (but that because the upper bass and
lower midrange is so nicely done) and one
reviewer suggested the treble needed to be
turned down 2 dB or so.
http://www.audioreview.com/product/speakers/floorstanding-speakers/dali/ikon-6.html
That was also the solution Nick Karayanis
offered to me towards the end of the night;
Jonathon later said he wondered whether the
grilles should have been left in place for the
demonstration. So, who knows?
If it's the third explanation, it goes to show
that bass and treble controls do have a place
in the modern amplifier - and here QUAD's
elegant tone-balancing system seen on preamplifiers
such as the 34 and 44 is unsurpassed. Another hurrah for Peter Walker!
Conclusions
I often come away from a members' request
night having heard a piece of music that
makes me want to pursue it a bit more. Last
month's meeting didn't generate that desire in
me, but it did demonstrate the diversity in
recording quality (and approach) across
different genres and musicians. The jazz
recording were uniformly nicely done, the pop
and rock ones often less so. And Track 11, the
Harry Belafonte, lived up to its reputation as
one of the best live recordings ever made. So,
all in all, it was an enjoyable and informative
night.
And hats off to Dave Polanski for organising
each month's demonstrations. It can be no
easy task. And to Jonathon and Moggie for
bringing along their gear for the night.

Critics criticised
It must be fun to be a critic. Jeremy Clarkson,
"when I have trouble sleeping, I think of Toyota
Camry. Dorothy Parker, theatre critic, "The
scenery was nice but the actors stood in front of
it." Or the restaurant reviewer who declared
"the pigeon might fly again, given a few volts."
Though fun, such barbs can be excessively
harmful. In the words of the careful reviewer
who wanted to stay in the borrowing list; "If this
is the sort of system you might like, you should
give it a good chance to explore it further at
home." So at our recent general meeting we
cruelly forced the amplifier into distortion. That
anomaly is to be forgotten as not a fair example
of the gear. Learn the lesson then if interested
move on for a fair Lux Audio demo. Never worry
that our guest is easily upset; he deals with a**eholes
every day. He's a gastro-intestinal doctor.

Titchy speakers abound
"A good big 'un always beats a little 'un" was one
of my father's wisdoms. He had built big
loudspeaker cabinets with super-efficient
Lowther cones and Mahler never sounded so
massive. What is it about the preponderance of
small 'domestically acceptable' loudspeakers--
when we are replacing our 55-inch TV screens
with 72-inchers. Actually, our GM guest
speakers take no less floor footprint than a
similar 50-litre floor-standing box, which yields
better bass Research finds that the bass has
some thirty percent contribution to sonic
enjoyment. I kept thinking while listening; one
is giving up so much for the sake of the visuals.
So just add sub-woofers, musical ones are not
thunder boxes, but add the music's ambience.
Having said that, the Dorfmann has more and
good bass than one expects from a small box,
achieved by a long-throw bass unit.

Who are those people?
There is always the wondering, "But who can
spend THAT MUCH on a CD-Transport." Or on
a nice Italian amplifier. Enough people, just not
simple wage-earners. They also buy a $50K
wind up watch to add to their collection. On the
other hand some of us trail a few years behind
upgraders and can pick up such gear as it gets
moved on, almost 'free to a good home.'

It sure looks attractive, in a somewhat
Germanic way. Form following function yields
a frame that hugs the box tighter than an
anaconda with a breakfast bunny. Reviewers
consistently discover after trying a range of
supports - they matter. A lot. In our hall,
(though not at home) some extra height would
have helped. Add the roomful of human
'meatbags' with their serious effect on soaking
up sound energy, and an uphill battle is
inevitable. Not to ignore the deleterious result
of over-pushing the Class-A 30 watt amp.
Riviera Levante
Riviera Levante
Ready to buy MACers
What is the real value of any MAN audiophile
GM dealer show and review? Because perhaps
one of us is currently in a keen-to-buy mode.
Unlikely, although I did once get entranced by
a GM presentation by Phillip Luder of Tivoli
Hifi of Nakamichi cassette decks. The lowest
model lived up to my hifi expectations and
budget, mostly for copying ABC FM. Looking
back, I was a foolish boy, single, with money to
splash.
Cables galore
Because we are Influencers
Is it worth a presenter's time and effort to put
on a show for us? Yes. Because we are seen as
'Influencers'. May we never spoil our
reputation as a MAC member with carelessly
dropped criticisms, in this review or at the
forthcoming HiFi show.
My mate John loves his music, has a decades
old average FM classical based system and can
spend whatever it takes to upgrade to a pretty
good system. "You know modern hifi what
should I buy?" I guess that a do-everything amp
-streamer would do it but held my breath. As I
have done with others, one told me that he was
thrilled with what they helped him choose. So I
took John to a nearby reputable hifi salon and
stood back without saying anything, and John
too was unimpressed and we left.
I truly believe John has the discernment to
recognise when eventually a good consultant
presses his buttons. So next we will be off to
HeyNow rooms at StKilda junction. In a salon
just like in our own music rooms. I have seen the
wide range of the good gear there, and I've seen
how Geoff Haynes sensitively guides a potential
customer to a choose satisfying audio decision.
I'll also suggest John accepts Geoff's offer of a
home trial of a better AC cord, just for lulz. John
just might get it.
Music, SPL Meter, Volume Knob
So what about (eventually) the sound? 'Good -
in parts.' But don't blame the gear tonight.
First music test piece, Richard Tognetti playing
Bach solo violin. Rather nice, but please "Turn it
up" (Ron N.) My son has played a violin in the
lounge at home and it was LOUD with lots of
energy. In the Willis Room only 80dB Cweighting
fast response via accurate enough
SPL. Commonly at home I listen at mid-80s plus
dB' via an affordable iPhone app by Studio Six.
In addition to the SPL meter emulating the
Tandy one, also a FFT (Fast Fourier Transform)
display of frequency distribution, and an SPL
display, showing here that there is not much real
low frequency energy below 40Hz. Surprise.
Furthermore, the Real Time Analysis showed
that about 70 percent of the music energy
covered the 0-2K frequency range, a pleasant
surprise to those one-eared electronically
supplemented quasi-audiophiles. Hey, do you
trust an audiophile with a hearing aid, a skinny
chef, or a catholic priest for sexual advice?
Rock track: Turn it up...The meter shows mostly
85dB, peaking upto 92dB, sounds 'louder'
because of the increased bass energy, with most
energy actually below 1K.
Aretha Franklin, 1967, 'Respect.' From a live
with audience recording. Did I make it feel like I
could be in the room, in the presence of the
musicians? The 'my Tough Test.' Not quite, but
there is no tougher test. Then when switched
between A and AB, the voting from some was
that the A was better.
Johnny Cash. Pleasing bass, up and down, not
one note. In audio, bass is hardest to get right,
also most expensive. But I'm worth it. Apart
from that - Distortion! At 90dB plus a bit, it was
on the verge of overloaded.
Doing the sums. peaker with a 86dB 1 watt
sensitivity, and inputting 30 watts,
sound level in dB 86 +10xLog30 (at Base 10)
86+(10x1.48)
therefore max Sound level (in dB) = 100.8Hz.
Your Porsche drives like magic until you try
to tow your yacht up a mountain.
Love over Gold, Knopfler, best solo guitar solo
ever. Some say. Quora online discussion
group, when someone throws in "Who is the
best rock guitar? Flames erupt; Page,
Harrison, Gilmour, Clapton, Cobain, Hendrix,
van Halen, Brian May?" Discuss. No it's Allan
Holdsworth, none other. Everyone knows how
they think this track should sound. Anyway
the guitar steel string sounded right. Though
still only at low 80s. At first. But wait! There
is more, peaking upto 107 at last. Normal
listening level explains Red. Who chooses
small speakers? People with wives. Oh.
Barbie-Pink Noise?
Even better for benchmarking (for those
among us thinking they are Real Audiophiles)
pink sound could be a First Track of the Night
every time because that clearer than any other
music -- with some practice -- points out the
deviations from sonic truth of the system.
Some thought that the voice is recessed.
These speakers have been A/B-d with real
music for studio monitors it was claimed.
Mixers' tastes vary so many speakers been
used in mastering rooms? Does that make us
think?
Corelli for the Classical crowd. Actually the
string sounds came through as relaxing, the
system as a whole not annoying. (Not meant
as faint praise. ) 'I could live with this' to fulfil
comfortable all-day listening is a tough ask,
rarely achieved.
James Morrison, who everybody loves
whatever he does. Even if the timbre is off on
this track, don't blame the system, it is the
mix with a piano level way over the drum kit.
Apart from that, the cymbals as requested
came through nicely. Rock drummers don't
speak the same language as jazzers (no
offence) but jazz works with and emphasises
hi-hat which can shimmer. Ching Ching Ching
Some of us are cymbal minded.
Boz Scaggs, thanks for turning it up though
about that. Dave C's 'Rainy Night in Georgia'
request featured soulful guitar Tony Joe White
wrote it and who appeals even to non-rockers
and MCC Members. Not earthy enough for a
Mr X?
JD McPherson with 'Signs and Signifiers' is a
subtle appeal to audiophile philosophers, in
which Plato distinguished the idea from the
object. In case anyone asks.
Watch out for the Fuzz
But not The Police tonight. Van Morrison and
friends, 'Stormy Monday' we used to call this
MOR (Middle of the Road) but we used
to think Bill Haley was Rock 'n Roll. Clean
distortion-free, nice. Enter Jeff Beck, he
pressed the Fuzz pedal, the one effect button
that has forever expunged rock as a genre for
testing pure sound. Adding distortion! Call me
an old man. I am. Fletcher and Munson are
spinning horizontally as their curve is being
used against us. Add dirt, it sounds louder.
Simple cheap trick. Keith Richards' '(I can't get
no) Satisfaction' from 1965 is a
good fuzzy example. [Wikipedia: The effects
alter the instrument sound by clipping the
signal (pushing it past its maximum, which
shears off the peaks and troughs of the signal
waves), adding sustain and harmonic and
inharmonic overtones and leading to
a compressed sound that is often described as
"warm" and "dirty", depending on the type
and intensity of distortion used.]
Have fun on YouTube exploring the variety of
fuzz boxes, as distinct from distortion or
overdrive, many available to taste. Bad taste
says Segovia, who also explained "There's no
such thing as an 'electric' guitar."
Don Ellis big nasty band shows once again
that without the deep bass, enjoyment is
diminished. I know this music from having it
at home, the big band excitement is forfeited
with small speakers.
Nick K has brought out Lisa Young jazz trio
previously. Here it sounded very attractive
with good and clean bass lines, once again
showing that jazz trio is not demanding sound
-wise, and why it's useful hifi demo genre, just
not demanding. ''I've grown accustomed to
her face' from, My fair lady, is a rewarding
soundtrack. Other movie or stage soundtracks
like Les Miserables, Sweeney Todd could
make a great home meeting theme.
A win, on points
So thank you gentlemen, for taking on a
hostile barn with a system meant for a living
room You gave us a look at some impressive
gear and a lot to think about.

Melbourne Electronic Sound Studio (MESS) |
Well, last month we were treated to another
fabulous presentation. The month before, it
was Damian Ware explaining why different
amplifiers sound different. This time it was
Byron Scullin from the Melbourne Electronic
Sound Studio (MESS, North Melbourne)
giving us an overview of the history of
electronic synthesizers and showing how their
knobs can be twiddled to generate the most
amazing sounds. Byron brought along three
synthesizers an EMS Synthi AKS, a Buchla
Music Easel, and a Make Noise Shared System as demonstrators. They were supplemented
by a virtual tour of the MESS . and what a
tour it was. Questions from the audience were
repeatedly answered with a "Yes, we have one
of those", with Byron flipping through the
virtual tour to show the offending instrument
sitting on a shelf, surrounded by an untold
number of its cousins. What a great position
to be in when you can answer "Yes" to every
enquiry from the audience!
For me it all fell into place when Byron took
control of the Synthi AKS and showed how it
could produce a refrain repeated throughout
Pink Floyd's 1973 The Dark Side of the Moon.
My liner notes to a remastered CD of the
album state that Dave Gilmour, Richard
Wright and Roger Walters all had a hand in
playing this instrument on various tracks. A
biography of the band (Mark Blake, 2007,
Pigs might fly: the inside story of Pink Floyd)
says they used a EMS VCS3 synthesizer for
sections of an earlier album, Obscured by
clouds, and started to play with it again to give
some structure to a track initially called
'Travel sequence', which until then had been a
self-indulgent, indeterminably long and
formless jam.
The rescue attempt wasn't entirely successful,
as Dave Gilmour admitted that "they couldn't
work out how to get any actual notes out of it".
Soon after this a Synthi-A, the cheaper,
compact version of the VCS3, found its way
into the Abbey Road studio where the band
was starting to record The Dark Side of the
Moon. They used the VCS3 on 'Breathe in the
air' and the Synthi-A on 'Brain damage',
'Time', 'Any colour you like' and, critically,
'Travel sequence', which had morphed into a
new track of only 3.5 minutes called 'On the
run' on the new album. Here then is the
fantastical basis of The Dark Side of the Moon
and so much of the Pink Floyd outre that was
to follow.
What makes Pink Floyd's music so distinctive?
For many people it's the masterful guitar solos
of Dave Gilmour. For others, it's the scale of
the performance and the wretched lyrics of
Roger Walters (or, given the band's fraught
history of interpersonal hatred, his haughty
attitude and never-ending commentary as to
who is the 'real' Pink Floyd). But for me the
soul of Pink Floyd always has been the
haunting, other-worldly simplicity of the
keyboard and synthesizer work of Richard
Wright, sadly the first member of the band to
die (in 2008, of lung cancer) other than,
famously, Syd Barrett (in 2006, but it might be
argued that his mind had died many years
before). No-one seems to think it's the
drumming of Nick Mason that is so distinctive:
is this an unfair interpretation?
And on my thesis that it's the synthesizer work
of Richard Wright that provides the
foundation to the Pink Floyd sound, it's
interesting that he used a variety of
instruments in their subsequent albums.
'Shine on you crazy diamond', from Wish You
were Here, used the VCS3, an ARP String
Ensemble and a Minmoog Model D. The
melody of 'Have a cigar' was performed using a
Minmoog Model D and the bass line using a
Hohner Clavinet D6 . Other instruments used
include a Roland Super JX-10, a Sequential
Circuits Prophet 5 and various Kurzweil
products (on The Wall and A Momentary
Lapse of Reason) and an ARP Quarda (on The
Wall). One website (https://equipboard.com/
pros/richard-wright) notes he never used a
Mellotron, an instrument widely used by other
bands in the 1960s and 1970s.
The reason I mention all this arcane stuff
about Pink Floyd is that Byron's presentation
brought home to me just how ubiquitous the
synthesizer (in its various forms) has been to
popular music from the 1960s on. Peter Xeni
noted that the 1962 'Telstar', performed by The
Tornadoes, was an early example in which the
synthesizer played a crucial role. According to
one internet source, the instrument in question
on that track was an overdubbed Clavioline
keyboard, played for the recording session by
Geoff Goddard, a studio musician.
And the Mellotron looms large here, having
been used in The Beatles' 'Strawberry fields
forever', an untold number of largely
indistinguishable Moody Blues' albums, many
songs by the lamentable Uriah Heap, and most
famously perhaps Tangerine Dream's Phaedra.
Even The Rolling Stones got into the act, with a
Mellotron being used on Their Satanic Majesties
Request to give it a psychedelic flavour. That
performance chameleon David Bowie used a
Mellotron on 'Space Oddity'. It was a favourite of a
untold number of prog-rock bands, such as Yes,
Emerson, Lake & Palmer, and King Crimson. And
on this topic of the otiose horrors of so much progrock,
it's perhaps fitting to mention Keith Emerson
of Emerson, Lake & Palmer fame, a great fan of the
Moog synthesizer.
But let's not forget that synthesizers were not
limited to popular music of the 1960s and later.
Lev Termin constructed his Theremin in the late
1920s, an electronic device in which the player
controlled the volume by waving his hand around
a horizontal looped aerial and the pitch by waving
his other hand around the vertical rod aerial. In
that decade we also had Thaddeus Cahill's 200
ton (yes, 200 ton!) Telharmonium, which used
giant inductor alternators linked to cogged
wheels to could produce electronic music over the
telephone network. It was used for the
soundtrack of 1951 sci-fi film The Day the Earth
Stood Still and found its way into The Beach
Boys' 'Good Vibrations' (1966). Imagine what
Keith Emerson could have done with 200 tons of
art deco electronica from the 1930s!
So, to conclude. It's probably fair to say that for
years the staple of the club's monthly meetings
has been presentations by manufacturers,
importers or retailers of specific pieces of
audiophile playback equipment. Invariably this
has been interesting, often informative. But
man does not live by bread alone and the
recent array of 'non-audio equipment' evenings
has provided a pleasant digression from that
staple. Just as I love well-made pizza, it's not a
diet I would like to eat (or my cardiologist
would recommend) for every meal into
eternity. Sometimes I crave the spiciness of
Indian food, or the magnificent diversity of
Greek food, a plate of tapas with some fino
sherry, or the down-to-Earth wholesomeness
of middle-European (Polish, Hungarian) shipbuilding
food, or the simplicity of battered fish
and chips, or the incomparable glory of an eggand-
lettuce sandwich with a coffee-flavoured milk.
Similarly, the diversions over the past
two months have added considerable variety to
our meetings. I see from Dave Polanske's entry
in the last MAN that July and August should
see the return of some equipment-orientated
demonstrations, then in September we'll be
treated to a run-down of the Australian jazz
scene, before a return to an equipment
demonstration in October. What a fascinating
audio diet we have before us. And I bet that
more than a few pieces showcased during the
forthcoming demonstrations will have a
synthesizer playing somewhere in them. Now,
thanks to Byron, we know a bit more about the
fascinating history and application of this
diverse family of instruments.

Damian Ware - Aurora Audio |
The Damian Ware demonstration
certainly created a lot of interest.
Good to see some discussion about
the "art" of hi-fidelity. It's obviously
inspired a few contributions to the
MAN this month. :-)
Equipment for the night including Whatmough Performance Trio speakers
For those who missed his bio here is
a quick sample of his credentials:
Damian's vision is to design and manufacture audio
equipment, which faithfully reproduces the sound of
instruments and communicates the emotional and
musical intent of the performer. Damian is an awardwinning
engineer and he studied at Monash University
under Professor Ed Cherry. Some here might know of
Ed Cherry; he is famous in the audio world for a
brilliant design with almost immeasurable low levels
of distortion. When Damian is not chasing Aurora
Australis or audio nirvana he will be often found
repairing rare, exotic vehicles.
Aurora Audio S2 Amplifier
Damian has built his all new Aurora Audio S2
Amplifier. The amplifier is a cost-no-object Class A
design created from the highest possible quality
components. The S2 produces 70W into 8 ohm load,
revealing every detail of the most dynamic high
resolution recordings. The S's tremendous dynamics
and perfect decay are accompanied by a sound stage
and tone to die for and this amp throws up a stunning,
real live performance.
Pre-amp, Rasberry Pi Music Server and DAC
Greg Osborn recently remarked: "The S2 is truly
excellent, the best solid state amplifier I have ever
auditioned and I have heard a lot of super expensive
systems at over 50 HiFi shows world-wide."
On the night he S2 was paired with Whatmough
Performance Trio speakers. These speakers have the
incredible inert John Woodhead lead lined cabinets
and premium cross overs.

Three hearty cheers to Dave our new beleaguered
Program Co-ordinator who has had more undeserved
knockbacks and setbacks since starting half a year
ago, than Nick would have had in any year..'
Excuse my scribbled notes. . Come back Paul Boon.
Audio Magic is a high end audio importer and
distributor, unknown to most of us until now. We
know Geoff of Hey Now Hifi, their number one
retail outlet, and it was Geoff with Alex and Peter,
who put together the selected system we heard and
saw.
HeyNow! is Geoff's dream hifi salon. After decades
being The Main Man at Tivoli, he jumped, took
some rooms in an elegant complex near St Kilda
Junction. He made his Listening Room One just like
many of us have, a comfortable living room, multipurpose
not just a dedicated wife-hostile audiotorium.
Tivoli do have their 'Divorce Room'
featuring Wilson monoliths and their ilk.
Geoff's way of operating is smart. He tells online of
all the brands he has. Actually 'has prompt access
to.' rather than holding every model of every brand
inhouse, a ridiculous stock-holding, . Phone Geoff, 'I
fancy comparing some Harbeths and the similar Elac
and Kef' and with short notice they will be get it all
in and ready for your appointment. From my
experience there three times, Geoff's product
knowledge is deep also honest. Geoff ran the Klipsch
night for us last year and several said, 'If I was in the
market I'd seriously consider those." (the eminently
listenable and affordable Model 5) Or if a buddy
said '"You know hifi, what should I buy? Think
HeyNow. Also, that way retailers get something back
for the big effort they expend in putting on a show
for the Melbourne Audio Club. It costs them, time
and staff overtime. He consults in the best sense of
the word, unlike the 'consultant' selling iPhones.
The horrors we came aware of early Wednesday
night seeing Alex and Peter huddled over their
iPad. Oh no! Not another failed connection,
essential in running any streaming session based
on Tidal. We recall the ultra complex multicomponent
system from a few months ago that
acted up bolshie and never came 100 percent
good. . It is fears of such setbacks that have
prevented some of us from ever getting into
networks and streaming then making decisions
that optimise the sound quality, let alone just
working. jRiver is a powerful user interface for
music stored on a computer, or from a paid
streaming service like Tidal or Qobuz. Yes, but with
power comes complexity, so many choices. For which
YouTube is our friend; "how do I solve...?"
YouTube has become a visual Wikipedia of just about
anything.
Peter from Audio Magic
And when it's all eventually back working again after
'improvements' mucked it up, bliss, a plethora of
one's collection all at the touch of the proverbial
button..On the other hand - the joy of random rediscovery
of an old favourite, on spotting something
interesting, 'Oh, it's been a while since I played that,
let's do it again. The pleasures that surprise us are the
best.
And so to the gear; and isn't this a bit like the night
already; 'Get on with what we've been waiting for'
murmured around the hall.
Is the loudspeaker the most important component? Its
style certainly contributes most to the overall sound.
Harbeth, the brand name as one would guess derived
from the founder Dudley HARwood, and his wife
ElizaBETH. Created over 40 years ago, his BBC
research showed that light rigid cabinet wall
resonances stored and released less energy in the
troublesome low range than thicker wood. They are
not alone in this approach, my Spendor BC1 TV
speakers retain the joy that comes with natural human
voice, if talking heads is the main TV watching.
We heard model Super HL5 Plus XD (for $10K a pair
but that's just a starting price, ask Geoff) , second
from top of the range, has a somewhat non-typical
speaker driver setup: 200mm (Eight inches) 'woofermidrange'
with a 25mm tweeter plus a 20mm super
tweeter upto 20K for air. Wilson, Snell and recently
PSAudio (at HeyNow) and others squirt 'air' out the
back of some of theirs. "Still, it ought to please any
passing bat." Who said that? Flanders and Swann.
Other figures in case anyone thinks it tells anything
(we don't) 40-20K, 86dB, 6 ohms. Audio Science
Review and others have gone for Spinarama which
usefully gives energy put out in all directions in space,
which tells a lot about in-room behaviour. Even-ness
matters, and sidewall bounce equals envelopment,
which we really, really like.

Some people sit at a desk a lot, and a small speaker can
be a dream. The Harbeth P3ESR for ~$5K is a shoebox
-size 2-way and is wowing reviewers. We are slowly
realising that a good little-'un can stand up for itself
against a good big 'un without apologising for much.
Is now time to talk about the sound? YES! Shouted the
crowd, after what seemed like an hour sermon. Talking
at length is more than enough about barely relevant
specs. What does crossover frequency tell us, yet we
always ask. Especially as all the data and more is on a
website. Admen know that the more similar a product
range is, the harder one must work to differentiate one
from its neighbours. So "100 watts but easily up to 145
watts' doesn't warm my tubes. Made in Denmark
(Copland) or England (Harbeth) not China is a
positive, where product quality can slip without a QC
watcher on the spot. Copland have specialised in
reliable good-sounding hybrid vacuum tube with solid
state for 30 years, and are Scandinavian gorgeous.

That is a USP (Unique Selling Proposition). In fact
PSAudio hired maven designer Bascom H King, who
was given carte blanche to design the best big power
amp he could. OK It will have a tube input stage,
because you promised. They doubted. He insisted.
They listened. They kept the tube. You want specs on
Copland integrated, its on the HeyNow webpage.
Lumin streameris a big name among people who
choose to spend what most of us think is a lot of
money. They think it is worth it for them; and who can
deny? Model T3 is about $7K. with DAC inboard.
Streaming this way has many appeals. It also raises
one major conundrum. What will I do with all my
CDs? Dixons? Sell them one at a time online? Salvos
Savers? Local school? Never, put them in my coffin.
Most people put them in boxes in the corner, along
with books one can't bear to part with 'because it is
what made me who I am' but will never re-read. We
say CDs sound better than streaming. Don't they,
searching for confirmation And handling a tangible
product is comforting. Isn't that what we said about
LPs? One of our audiophiles who took the jump to an
Auralic Aries laughs. "The music, it's all - and more -
on my Tidal." I have.to set up an Aurender music
server/ streamer with high hopes it will better the SQ
(Sound Quality) of my CDs.

Ayre acoustics, near the top of audioland. are held in
high esteem Their $$ CD player had better deliver to
hold its place in this age of streaming. Were we nightand-
day stunned with comparisons on the night? I
think not. But of course, not in critical listening
gear and reviews online, that way one gets a general
consensus of the place of a piece of gear compared with
similar others.

Oh, and Tellurian Q interconnects. Priced in the up to
$1000 range, is 'affordable' in general.. The word means
'pertaining to the earth' so ...Underground Audio like in
early days High-End? Anyway what is their USP, ya
gotta have one. Roughly translating from what the
brochures say; 'It sounds better so in what way, and how
do we do it? It's a trade secret so we can't tell you.' At
least they don't use geek-speak drivel like many. "We
suck less"
TonTrager (German = 'Sound carrier') speaker stands
come from a factory 'surrounded by a breathtaking lake
scenery in the Bavarian Alps'. That's useful to know?
Ad-man says "don't waste your money promoting the
factory."
Is it now time to talk about the sound? YES! Shouted the
crowd, Without more ado , too much ado already. To
the music.
First track choice is jazz piano trio, with upright bass and
standard jazz drum kit. This choice surprised and
pleased the jazz aficionados among us, often treated as
music orphans. On the ecm label which MACers love
for its pristine sound, a Polish recent jazz darling Marcin
Wasilewski, plays "Riders on the Storm" (Doors) a
tune not readily recognised here, SoundHound app could
identify it. The music is mostly harmless, it would also
make useful easy listening background music at a formal
dinner party, so please never again The Four Seasons.
Since discovered: The CD is
"Fancy Cocktail Hour Jazz" so
that wasn't derogatory.
Sonic impressions were an
extended, balanced frequency
range top and bottom,
comfortable, with plenty of live
presence. Nothing at all wrong,
comfortable. I could live with
this. Alan Shaw, the designer had
previously believed his consumers
were all into classical, hence the
BBC voicing of all earlier BBCvoiced
Harbeths. When disabused
of this, he turned it up to a more
modern sound; kept the magic
midrange, for the pop-ers gave it
dynamics that don't suck, with
added but still pure twinkling
trebles. Hence the 20K super
tweeter, because those frequencies
do intermingle with those lower
down. This Grumpy Old Man
would have loved the bass to go
down lower than on the night in
the hall or on the recording. Specs
tell of down to a proper 40Hz so
I'm no accredited golden ears, just
tin or lead perhaps.
In jazz music, the ride cymbal is king. It shapes the
feeling and rhythmic subdivision of the tune, and
creates a foundation for everyone else to play off.
Unlike Funk or Rock music, which is built from
the bottom up (meaning that the bass drum and
snare drum are the essential parts of the drum
beat), Jazz music is built from the top down. [From
LearnJazzStandards.com]. Are jazzers cymbalminded?
Why do we get so much piano trio jazz from hifi
demonstrations? Because jazz trio always sounds
good. Given that, what is most usefully revealing,
to differentiate good sound from excellent? Female
vocal, (because we know what women sound like,
and bachelors therefore make bad reviewers) Also
very useful is symphonic orchestral music, such as
tasteful small samples Ron and others choose for
GMs. We should have more. Harbeth loves
violins.
Second track (Phew!! - but hey it took this long on the
night to get here) another (Yikes!) jazz piano trio
"Beat" from the Tingvall Trio I felt the bass to be fat
but MAC opinions of bass vary as much as. where you
sit. I wonder if the port which extends the bass down a
couple of notches also makes it less tight, more fruity.
Online reviewers love this pat of the Harbeth sound
so there you are.
"I could play this music all night" admitted presenter
Peter, which prompts thinking about how we choose
a music program. He might be twenty years younger
than our median age, he mostly exposed to recent
releases (tonight were since 2020) and we know that
one's taste in food, music and many things is firmly
set by a certain age.
Searching for opinions of the night's later music
pieces fed some useful opinions, and are offered here
later.
Program details are skimpy hereafter - For those who
want to follow up an artist or avoid i
Joey Alexander, "Angel eyes." THIRD piano trios!?
Next up Diana Krall who would be surprised?. This
version stimulates comparison with the stunning
Cheryl Bentine on 'Duos' with Rob Wasserman. In
the same way Frank Sinatra compares with Michael
Buble.
Sonics? No opinion Honest It's time to confirm that
as a hifi sonics reviewer I would make a good
gardener. Recently one ear went bung - likely Covid related -as deaf as if you put one hand hard against
one ear. My audiogram shows a scary plunging
dropoff around 1-2K End of my hifi story? Actually
no. For a start, it is reassuring to know that more than
a few of us use hearing aids - with good or not so
good results with music. My experience seems to be
that one good ear is pretty useful (Thanks God for
providing us a duplicate for so many organs).
Surprisingly and fortunately, headphone listening is
still very rewarding.
We should not be too disheartened with age-related
hearing drop-off.
"Hearing loss at age - the good news." Hans
Beekhuizen's YouTube shows how a great deal of the
important energy in music comes surprisingly early in
frequency.
All the tracks so far have been provided from Tidal as
24/96, [PLUS MQA the complete parcel] although that
doesn't guarantee they were recorded thusly.
Nevertheless as someone announced, "So clean, it
shows." Maybe. Many tests find that only a super-fi
system can distinguish true hirez from RedbookCD.
Ray LaMontagne, "Trouble" Pop Rock/Folk, a
raspy heartfelt voice. Not very engaging to me.
Lady Blackbird, "It'll never happen again." Black
acid soul.
Karen Souza "Tainted Love" "Stella Starlight
Trio" (who would have been surprised? Some nights
you even wish for D Krall) Volume hit only high 70s
dB, surprisingly. Bass showed on a iPhone AudioTools
FFT meter to be predominantly only around 60Hz. Do
we all need sub-woofers. Ask anyone with subs.
Kandace Spriggs with Nora Jones, The women who
raised me; "Angel eyes." R&B. She's no Nina
Simone. : I wouldn't mind some Amy Winehouse,
wishing for something real."
Ely Bruna I like Chopin, "Remember the time." I
like Patricia Barber.
Amy Winehouse Back to Black dragged screaming
and resisting to us as is her way; Ah! Real. Neo-soul,
gutsy music. Rugged charm and deeply personal song
writing. Dark enough for you? Soundwise? I forget.
Comes the time for the audience to choose.
Immediately it was clear we have more useful track
suggestions than young presenter Peter likely ever
knew about. Jazz at the Pawnshop? I wasn't even
born then.
Shelby Lynn "The look of love." She is not Dusty
Springfield. I'm still a grouchy old man. but much of
what is new is crap so that's reasonable.
Yo-Yo Ma Appalachian Journey", on"Classic Yo-
Yo" collation 2001. His agile cello with his friends,
he never fails.
Ruthy Foster. "Phenomenal Woman." introduced
by Martin W recorded at a live 2011concert, which
stood out acoustically versus everything else sounding
studio-miked,. Better music also IMHO, Winner on
the night.
It takes a good system to differentiate such audio
subtleties, and this GM excelled in accuracy.
We come to a GM to meet the guys, to perve over the
gear - thanks Audio Magic - and also to follow up
desirable music that grabs us. Ruthie did that for me,
her expressiveness is reminiscent of Aretha, the --fi
not as hi- as some tracks, doesn't matter, sounded
good played back at 85-90dB plus the image
appealed. I for one decided to follow her up, the best
recommendation.
It does rather look from reading this report that if the
Harbeth Super HL5 Plus XD are missing enthusiastic
positives, then they aren't all that good. That would be
so WRONG! It is easy to criticise, hard to say nice
things when everything is lovely.
The Harbeth is Hippocratic, it does no harm, is
blameless.
Reading online opinions by trustworthy audio
reviewers, you learn about a speaker that does it pretty
darned well in every way, a speaker that would please
most of the people with most of the music, most of the
time.
People have said when reflecting on our previous
GM, But why buy new more costly loudspeaker when
a vintage TimeWindow does the job pretty well. Not
perfect but good for the money.
Well when thinking about getting a replacement
car, when offered a choice between a Toyota Corolla
which is pretty useful for the price and a Lexus, what
would most really prefer?
"The quality remains, long after the price is forgotten." - Sir Henry Royce, founder of Rolls Royce.

"History is more or less bunk. It's tradition.
We don't want tradition. We want to live in
the present and the only history that is worth
a tinker's damn is the history we make
today".
So claimed Henry Ford (1863-1947), the
pioneering American car manufacturer,
phenomenally successful entrepreneur and
industrialist, virulent racist, vehement anti-
Semite, rabid opponent to worker's rights,
fervent believer in conspiracy theories, and
recipient in 1938 from the Nazis of the Grand
Cross of the German Eagle, the highest
honour they could bestow upon a non-
German - yet the same man whose factories
contributed so mightily to the anti-fascist war
effort during World War 2. (Ford's assembly
plant at Willow Run, Michigan, alone
produced 8,645 massive, four-engined B-24
Liberator bombers during the war, at peak
production one plane coming off the
production line every hour!)
What's this got to do with the audiophile and
our club? Well, last month's meeting showed
to me that (1) history is not bunk and (2) that
not all of us want to live solely in the present. I
say this because of the almost ancient
equipment used on the night and the high
quality of so many of the even-more-aged
recording proffered by the members.
The equipment came from the backroom of
the club's president, Ian B: a low-to mid
range Marantz CD player about 8 years old, an
integrated Denon amplifier from perhaps the
early 1990s (putting out ~60 watts per
channel) and a pair of slightly tired looking
DCM Time Window speakers. It's the speakers
that aroused much interest on the night and
form the basis of this report
The Time Window was released by DCM (based
in Ann Arbor, Michigan; and the abbreviation
'DCM' does not stand for 'Drug Capital of the
Midwest') in 1978 and went through a number
of iterations over many years, with Version 7
being the last to date (I think). There's a bit of
uncertainty as to what drive units were used in
the different versions, but from what I can tell
all shared an unusual layout of a pair of 6.5"
midrange-woofers on each side of an angled
front panel, each one positioned above a dome
tweeter (Figure 1). A brief interrogation of the
internet suggested the midrange-woofers in the
original, Type 1, Time Window were made by
Philips and/or Heppner but the tweeters were
consistently the widely used and respected
Philips AD0162-T. The subsequent Type 1A
version changed this for the VIFA TD-19
tweeter, a device that found lots of applications
in proprietary speakers in the early- and mid-
1980s. I, for example, had a pair of massive 3-
way kit speakers from, I think, Electronics
Australia that used this 19 mm tweeter, along
with a 3" VIFA dome midrange and a 12" VIFA
bass driver.
The idea behind the angled and multi-driver
layout was to create a very wide sound field,
with the inner face responsible for direct sound
to the main listening area and the outer face
creating a diffuse sound field that bounced off
adjacent walls. It is interesting how this idea of
using direct and reflected sound was so
common in the late 1970s: my much-loved
Sonab TL12s attempted a similar trick, as did
the more dubious Bose 901s.
The crossovers of the DCMs were pretty
complex for a two-way system, with one
diagram available on the web showing three
inductors, four capacitors and two resistors.
I don't know what the crossover
point is, or the order, but I guess a clever soul
could calculate both from the values of the
individual components. Notice that both
tweeters are nominally 8 ohms: interesting
when each speaker has two of them and the
nominal impedance is also 8 ohms.
The bass loading was also novel. Consensus is
that the Time Window was fundamentally a
bass-reflex design with an offset pair of short
port tubes (2" diameter and 7" long) tuned to 35
Hz, and the long, linear space inside the
cabinets packed with a filling of variable density
(as in a transmission line).
Clearly a lot of thought went into this speaker.
The minimum impedance is cited as a friendly 5
ohms and sensitivity as a rather good 89 dB.
The cabinets are narrow (15"), skinny (12") and
tall (36"), and covered like a sock with an allround
cloth (again, refer to Figure 1). Tops were
bits of shaped wood. Once seen, the DCM Time
Window is a speaker not easily forgotten. And
as we were to find out shortly, once heard they
are not quickly forgotten either.
Everyone I spoke to on the night was taken
aback by the sound of these 40+ year-old
speakers. My impressions over the first few
tracks were of a rather dominant upper bass, a
hollowed out, distant and reticent midrange,
and a bright, crisp treble. But I've learnt over
the years never to trust the Willis Room to
provide a good bass response, so I soon
disregarded this initial 'objection'
to the bass response. My concerns
about the midrange were also
quickly dismissed, this time by
about the third or fourth
recording. I realised that the
seemingly uncommunicative
midrange was, in fact, most likely
a property of the first few
recordings and not an inherent
property of the speakers. Better
recorded tracks revealed a much
nicer tonal balance. Either that or,
as Ian pointed out in his
introduction, the various pieces of
equipment had by then adjusted
to having electrons pass through
them again, having sat idle for
years previously in a back room at
his place.
I overheard the past-president, Martin B,
sitting behind me, say this was better sound
than he'd heard from some new $30,000
speakers that had been demonstrated at
monthly meetings. And we are not alone in
singing the praises of the Time Windows: the
web is full of people saying nice things about
them, even four decades after they came on the
market. My revised, positive feelings towards
the speakers were confirmed with two very
clearly recorded tracks on the night, both
played just before the coffee/tea break: the
Swedish jazz pianist Jan Johansson's Visa fran Utanmyra from 2014 (Arthur S's choice)
and the more funky jazz of Bob James' 1983 Foxy
(Chris M's choice). Both were startlingly
clear and three-dimensional, even with the
shabby acoustics of the Willis Room.
And this brings me to the second reason the night
showed that history is not bunk. To my ears, the
best vocal pieces were the two songs by Elvis
Presley and by Frank Sinatra (I forget who
contributed them or the details of each song:
blame the memory lapse on my medication). In
both tracks I detected a real-life, breathing
human being, singing in a real-life space,
accompanied by a real-life musician or two,
performing to a real-life listening audience (or
studio staff), in real time and in real space, all
working together in sympatico. So many modern
tracks are often obviously close-miked and multitracked
a million times, with the result being a
dynamically thrilling but emotionally
unrewarding sound. How is it that two songs sung
and recorded in the late 1950s or early 1960s
could sound better than stuff done in the more
recent 20 or 30 or 40 years, with all the
technology we now have at our disposal? I reckon
it's because they were simply recorded, probably
in mono or at best with a three-track tape
machine, in a real studio with real musicians
playing together in the single space.
So, two sets of evidence from the night indicated
that history is not bunk and that Henry Ford was
wrong in his diagnosis. The first is that a pair of
innovative speakers over 40 years old,
driven by an inexpensive amplifier over 30
years old and a relatively inexpensive CD
player, could sound so good. The second is
that the best sound of the night (to my ears)
came from tracks even older than the
speakers, things recorded perhaps 60+ years
ago. Who wants only the new, then Mr
Ford?
Let's finish with two other quotable quotes
from Henry Ford:
(1) "Exercise is bunk. If you are healthy, you
don't need it; if you are sick, you shouldn't
take it" (He did live to the ripe old age of 84,
so perhaps he was onto something here?)
(2) "How come when I want a pair of hands,
I get a human being as well?" (Reflecting a
deeply ingrained misanthropy perhaps?)
An interesting, if deeply flawed, human
being.
