I've just installed a Terratec EWX 24/96 which on paper at least could be better the the M-Audio Audiophile card. I haven't managed to get proper DD/DTS passthru working yet, but I am running Windows XP so probably no real suprise. CD playback though really is superb, I actually thought that my Live! wasn't that bad, but this blows it out of the water. I now have the best hifi that I've ever owned and its a PC!
