i was on the whole ipod, itunes, mp3 kick untill a couple months ago. i stopped worrying about getting my system crazy loud and started tuning it to sound good and have good SQ(with the inexpensive setup i currently have). i found out about a program that you can use to make all your mp3's have roughly the same "volume". it also tells you if the recording is clipped or not. almost all my mp3's, even ones i took from cd's i had were sometimes severely clipped. they were all lowered to the same volume now after running that program but still didn't sound right to me. now i only buy cd's and barely use the ipod anymore. i might use it for longer trips on shuffle or when i feel like playing rapp which sucks in the SQ category anyway. most cd's i find sound pretty good but some do sound a little muddy and distorted in the upper end.
