Well, if I were you I'd convert your ripped .wav files to something like raw audio data -- .wav is a generic format that has all sorts of bizaare variants, but mostly I'd suspect suble differences in the header which render your comparison useless (unless it comes out the same :)). They can for example record free form comments, which from a cd ripper might record the date and time of the rip. There is also some padding which happens on the end of cdaudio tracks. I'm not sure if you get that in the ripped file or not. I assume it would be the same for both the source and the target disks, but I'm really not sure. I'm not actually up to date on audio formats atm. .raw seems like a safe bet to me. Then using diff or something to compare the files. Maybe even vimdiff, so you can see if the errors are at the very start or end (since those errors are meaningless manifestations of protocol).
