You will be further ahead looking at Firewire interfaces. I can recommend this one from personal experience:
EDIROL FA-66 24Bit/192kHz FireWire Audio Capture

Dave, can you post basline RMAA measurements of this unit, with no DUT connected?
From my tests, it doesn't perform as well as say a E-MU 0404 USB.
Yes it does (24/192) and can even do 32 bit measurements.
