He has no choice but to use the FastTrack...at least the converters. How else to get the signal into the computer? Maybe you are implying that he can bypass the preamps in the fastTrack by using the line input and keeping the gain at unity. I use my emu 0404 with an outboard preamp and it seems to work very well. I've been told that the line input bypasses the preamps on that unit...don't know about the FastTrack.
