Thanks for the info but I still have a few questions. Does the AI3 support 96 KHz like the ADI-8 DS does? I know it supports 24 bit, which is useful. Does the ADI-8 DS do anything the AI3 can't? the price difference is huge, and I don't really see all that much of a difference. Thanks! Robert Cohen Also, where can I find a copy of the HDSP 9652 drivers?
