ETA will be mid to late September

A high quality phono stage that suits moving coil & moving magnet cartridges with lots of user adjustment for fine tuning. Custom adjustments are performed using jumper settings on the PCB. The lid comes off easily to gain access to the various settings which are clearly labelled. This is a little more inconvenient than the usual DIP switches but means reduced internal PCB track lengths and a slightly higher performance. Top priority has been given to the power supplies as this has a huge influence on the sound. The case is a quality all aluminium custom design imported from Japan. The unit is powered by a C ticked Australian approved external transformer with dual 14.8v outputs. This enables a pure linear design with lots of headroom which is very important in a phono stage. All components are top quality including the dual chokes which are sourced from the US. The RCA output connectors are from a large reputed Taiwan manufacturer - solid metal design with Teflon insulation. Resistors are all KOA Speer semi precision metal film and hand matched in critical areas. Main filter and decoupling capacitors are all Nichicon and a combination of KG Gold Tune, KZ Muse and FG Fine Gold series. Phono equalization is performed passively using hand matched polypropylene capacitors & metal foil resistors. In the next few weeks I will do some precision measurements which will be added to the website.
