c9-2001 I have to disagree with you on that "best" audio quality statement. I had a delta 1010 but I didn't find it any better than my MOTU 2408 in fact I felt it didn't quite measure up, so I returned it. The delta 1010 is a good card but not the "best". Now if we really want to talk about quality cards I would have to say the RME Audio cards are solid stuff, followed by MOTU.
i record almost everyday with a delta 1010 and motu 2408mkII,,, the motu doesn't sound as good, and the delta an rme multiface sound 100% the same...
the best sounding card is the StAudio system III
