This month we welcome back Warwick Freemantle from the Pure Music Group. It was two years ago when Warwick introduced to the club, a new range of Australian designed and made electronics from Open Audio Design. Jon de Sensi, the chief designer and owner of OAD, has developed a new stand-alone Phono Stage for the Australian market. The OAD UP1 Phono Stage is a two-box device with a separate power supply. The main box contains the electronics with two separate boards for each channel.
One of the design criteria for the UP1 was to provide enough gain so that it would suit even the lowest output moving coil cartridges. A general MM 40dB gain or MC 60dB is the first step, then a separate set of dip switches are provided for an additional 20dB of gain, in 5dB increments. Six cartridge impedance loading switches are provided along with three capacitance settings, ensuring that you can match almost any cartridge to your system.
Warwick will be demonstrating the phono stage with a Kuzma Stabi S turntable with a Stogi S arm. This minimalistic turntable features a heavy cross-shaped tubular brass chassis that uses rubber O rings for decoupling purposes, doing away with the conventional suspended sub-chassis. The rest of the system will feature the ATC CDA2 Mk2 CD player/DAC/Preamp. With both CD playback and plenty of inputs - both analogue and digital - the unit can accommodate all your additional sources.
Designed to drive long cable runs when connected to active speakers, the CDA2 Mk2 makes a perfect match to a pair of ATC SCM50 ASL speakers. These 3-way floorstanders house the famous ATC 3" Soft Dome Midrange driver. A 25mm Tweeter takes care of the high frequencies while the 234mm/9" Bass driver incorporates ATC's unique Super Linear Magnet technology. Each driver has its own dedicated and individually matched amplifier manufactured in-house, totalling 350 Watts per speaker.
Looks like we will have another full house for the night, don't be late.
