I switched back in October 2001 and haven't looked back. UA5 has been solid for 24/48 using the MME drivers and nTrack or Sound Forge 5.0. I also use V3>VxPocket without any issues. The UA5 has been very unreliable for 24/96 - I've had success in the past, but the last few I've tried had 'skips' in it so I've given up for now. 24bit sounds excellent - enough of an improvement over 16/48 DAT that I have no interest in turning back.
