Very interesting. How much of the song were you playing at a time and did you have to change discs in the player, (ie how long of an interuption between one disc and another)?

I had to correct the volume level of the MP3 to match the other, was your MP3 stuff at the same db level as the original? (this is probably specific to my player setup situation but you never know, obviously people would pick out a volume level difference and could interpret this as quality. . .ie the bass and treble not hitting like they should)

Thanks for testing this out. Hope more can also so we can get some kind of consensus on the MP3's
