yeah mp3's ruin the sound quality that's for sure. by killing the compression on the low end, and scrambling the high-and leaving the mid range to stab you in the face.
i try to get my mp3's over 192 kb/s, and when i rip cd's i don't go under 320 kb/s.
even the standard, most popular 128 kb/s sounds like crap. and no one really realizes it or cares.
