Exellent link, here's the DAC:
M-Audio Delta 44 & 66-AK4524 (Envy24,AKM AK4524)
Well, it's got this breakout box, so I may take it apart and see what other bits are in there apart from the DAC.
I guess it isn't quite as good as the EMU, but I wonder how it would stack up against something like the AlienDAC? I've ordered the kit, but I guess the best way would be listen to both sources, and see which one I prefer.
