8pm Wednesday 21st March - Willis Room, City of Whitehorse Offices
Melody Valve Ltd.

2016 was a landmark year for Melbourne audiophiles, for it was a year when two International Hi Fi Shows came to town. Not only was it a first time for the StereoNet group to organise a very successful show, it was a first for Melody Valve Ltd to exhibit all of their new amplifiers. This month we are very lucky to have Melody present at the club.

Established in Melbourne by the founder and chief designer Mr Allen Wang, the company has grown by investing in their own factory in Shenzhen China. It features a modern assembly line, a transformer production line, a vacuum processing plant and a variety of self-built high-end testing equipment. Their current line of amplifiers consists of eight models.

Melody will be demonstrating two systems from their Everest amplifier range. The equipment will consist of a 28watt Class A Integrated amplifier, and a Pre/ Power combination. The first model the "Everest 845", uses a Western Electric 845 tube per channel, as well as a pair of 300B driver tubes. The second system will be a pair of mono blocks - "PM 845 EVO" -- each running a pair of 845 valves in Class A mode with a combined output of 70 watts each. The "WE2688 Signature Pre", is a real highlight with its implementation of a WE 416 tube; planar triode, used for microwave telephone systems, that looks like a round metal relay.

The two systems will use the same pair of speakers, the Harbeth 40.2. This reference monitor is a 3-way stand mount model that houses a 12" Bass driver with 6.5" Mid and matching 1" Tweeter. Harpeth's top of the range speaker is modified for the domestic audio market with a different bass driver, but still retains the same mid that is used in their studio monitors.

If you haven't experienced Melody's presentations at the past Hi Fi Shows, you will see why they get the award for "Exhibitor who tried the hardest to impress". Sounds like we're in for a sonic spectacular.

What we did last month
Pure Music Group presents Open Audio Designs

A New Year has started, and it has brought to the Australian Hi Fi scene a new player to the market. Warwick Freemantle from the Pure Music Group will be demonstrating to the club a new range of electronic components from Open Audio Designs. The man behind this new company, Jon DeSensi, will be our guest presenter for the night.

Jon's new products, a pre and power amp, have raised the bar for Australian High End design and manufacturing with world class sonics at affordable pricing. The CP1 pre- features a 4.3" TFT LCD Full Colour display, with capacitive touch. All features of the CP1 are controlled by this touch display which eliminates any front panel mechanical potentiometers and switches. Gold plated Swiss made relays select inputs, followed by a buffer amplifier that presents a benign load to signal sources. With few components in the path as possible, a direct coupled dual mono layout helps to maximise audio purity and virtually eliminate crosstalk.

The UF1 Power Amplifier utilizes the latest in transistor technology to deal with significant distortions. As the load impedance of an amplifier is decreased, large signal non-linearities begin to appear. This distortion is significantly dependent on the quality of the amplifier's output stage power transistors. The UF1's transistors are in a different class, in that the current gain is completely maintained over its full power bandwidth, while also minimising the crossover distortion.

Partnering the electronics will be a new speaker from Gauder Akustik, the Berlina RC-7D Mk II with the Accuton Pure Diamond Tweeters. Argento Cables will look after the signal from each component. With the optional phono card (PP1) installed in the preamp, the source for the night will be the Kuzma Stabi SPS Turntable with Kuzma 4 Point 9" Tonearm. This will be OAD's (OPEN AUDIO DESIGNS) first public showing at an audio event. We may well have a full house.
