I agree with Kenn39. Lossy compression means you lose things in the compression process--takes advantage of the pschoacoustic coding mechanisms Duane was referring too. Lossless compression means smaller file size but no loss of data integrity. If you rip SongX.wav in WAV (raw PCM data in a DOS file wrapper), convert to Apple Lossless (SongXv2.m4a), and then reconvert to WAV (SongXv3.wav), SongXv3.wav and SongX.wav will be bit-for-bit identical. Note, this is not true for "lossy" compression like mp3, AAC, etc.
You might see if you can get a different USB device before changing out your DAC. I never liked the M-Audio I had with toslink; even my old Edirol UA-1D and digital coax sounded better. I really like my Waveterminal U24, but gather they are no longer manufactured.
