I have replaced my Audioaero Capitole with the Zodiac Gold + Voltikus combo and about 500 hours on it now. I run it off a Mach2music Mac on PureVinyl and have detail, texture, colour and soundstage ambience to die for. The USB connection is fantastic provided you use the right cable and the setup on Mac OS is really easy. I run the Zodiac direct into my Wavac EC 300b and use the analogue inputs for two vinyl connections: no hum, no noise and beautiful music. Whatever Zodiac knows about clocks and attenuator design has gone into this and the result is absolutely stunning.
