XDA2 was their last one I believe and they had the pro audio style one also.
I think everyone has shied away from stand alone DAC's, I know parasound makes a decent unit the half sized zdac, but even they got rid of the standalones and now they are all "preamp/dac" units...
I love a simple system, just digital source plugged into the dac, dac plugged into the amplifier, amplifier plugged into the speakers.. something clean about its simplicity...
