Nope....but maybe you can tell me something...
I do run win2k and I really like it for speed/stability, but no Audiophile in my system (yet). I currently have a Midiman 2044, which I did manage to get working under WinME even though the driver support stops at Win98.
Anyway....I do like the 2044's sound quality even at 20-bit dithered down to 16, but I'm looking for support for (you guessed it) win2k and latency better than 68 ms. I know the Audiphile would have better latency and I'm pretty confident that it will run well under 2k based on what I've heard. But, I have one little question about the card, does its MIDI interface have any better timing than your average SB Live or equivalent consumer sound card? If not, I'm inclined to either stick with my current card and get a real MIDI interface or get a Delta 44 or 66 and a MIDI interface.
I know the implication of a more professional card like the Audiphile is that it would have better MIDI timing, but I would like to hear from someone who has actually noticed the difference, if there is one.
