[QUOTE="DiDan, post: 4177823, member: 564477"] in fact CD-ROM drives do not have an error correction especially for audio cds, they only try to correct the bits itself e.g. using the CRC checksum. audio-cd-players have an built in error correction for wav. that is how some copy protected CDs work, they have errors on it an audio-cd-drive corrects without much thinking, your computer cd-drive gives you an error because the cd seems to be damaged. but nevertheless all new decks that can play MP3 do not have an audio-cd-drive and therefore do no more have this error correction. that is y some SQ-decks do not support mp3, like the clarion 9255 or pioneer P90. but a good computer-drive is as good as an audio-drive as long as the CD is not badly scratched and damaged. but with USB beeing a digital connection its better to have full-speed-ipod-interfaces, so that the D/A convertion takes place in the HU, not in the crappy ipod D/A converter.
