Edwards Audio MC1 Mk2 Phono Stage



MC1_Mk2The Edwards Audio MC1 Mk2 Phono Stage
 is our first all in one PSU and Phono stage for  moving coil and moving magnet cartridges, though we venture to suggest that it is not entry level in performance terms. It is unique at the price, with its fully RoHS compliant, gold plated, custom made, double sided PCBs, natural anodised extruded aluminium case and high quality internal parts like its use of 1% thin film melf resistors from Vishay plus Panasonic low impedance PSU capacitors throughout.  The RIAA. Equalisation accuracy is within 0.25dB across the audio band and signal to noise is low at -68dB ( ref 500uV input). With a full 110dB dynamic range.

Our psuedo balanced discrete input technology gives you the option to optimise grounding to reduce the possibility of Hum/noise. The circuit topology has a fully discrete input transconductance gain stage followed by our unique op-amp based bass active treble passive RIAA filter which is followed by a totally buffered output section with a very low output impedance. This helps to reduce cable effects and improve output current and drive. It will easily drive a 600 Ohm load! It features standard gain for both MM at 42dB and MC adding an additional 23dB, these were chosen so that the MC1 can be used with the majority of normal pre-amps. If you need adjustable MM loading OR extra gain and special loading for High output MC then why not look at our MC1 PLUS version

Attention to detail also extends to the custom made plug top power supply, which with its use of a split rail design benefits from using + and – DC power outputs for better rejection of RF noise.  It also uses a gold plated custom made PCB with high quality diodes and optimised snubber caps. This is no normal ‘off the shelf’ PSU as used by our competition…

Most importantly, it also delivers in the sound department as well, with expansive and detailed sound staging, drive and dynamics that are normally associated with more expensive phono stages. It can be further  upgraded through the use of the dedicated PSU1 outboard Power supply. Don’t just take our word for it though, as you can see below we are racking up the awards as proof of its performance.
