Houstonreef, are you saying that a WAV file of an MP3 source sounds better to you than the original MP3?
Forgive me if I am stating the obvious, but it's the quality of the source material that defines how good any given file format (native or lossless) will sound. Furthermore, MP3 and AAC are lossy formats which subtract data from the full resolution source. Ideally, you should rip from CD to WAV, AIFF (for Mac), FLAC, or ALL (for Mac). The last two are lossless compression formats, and are bit perfect.
