Obviously the author of dbPowerAmp has probably forgotten more about CDROM drives than I will ever know, but I do find this statement to be contrary to my empirical experiences.
Example: I recently made the mistake of buying a used CD on eBay, and it had uncorrectable errors on the first and last tracks. I tried a number of drives (Samsung, LG, Teac), and neither dbPowerAmp nor EAC were able to obtain a clean rip, whether in secure or burst mode. So I played the CD on my DVD player (a cheap Cambridge Audio model) and recorded the SPDIF output using a M-Audio 2496 card. No audible glitches can be heard on the resulting files. I simply cannot believe that the DVD player didn't suffer those uncorrectable errors, so I can only conclude that it masked them with interpolation, while the CDROM drives I tried did not. Unfortunately my Plextor PX712A died some time ago, but I am fairly confident that it would have been able to do the same trick as the DVD player - it had done so on a few other bad CDs in the past. But that Plextor was the ONLY drive I have ever owned that was capable of this. -- cliveb Transporter -> ATC SCM100A ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=51311 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
