I would first make sure that the A/D converter is top notched (don't just look at how many bits it supports but look for the actual noise floor numbers, whether it supports balanced inputs, etc etc -- the stuff the professional recording world looks for), with gains in the audio chain adjusted for maximum dynamic range and never clipping (RITTY has always bragged about the use of a non-limiting front end, for what I believe are solid reasons), and with as much hum/noise removed as possible.

And don't forget the RightMark Audio Analyzer program, to check how well the sound card is doing in your machine environment. Free download from:
