I strongly doubt the CD version and HDCD version are mastered the same--in which case the FLACs for the two versions should sound markedly different. You've got to route everything through the same DAC and other hardware or it's not a valid test, sorry. Otherwise you can't say for certain the difference you're hearing isn't from the difference in quality between the two DACs, and not the compression at all. That's the breaks when you go the science route. All variables have to remain constant except the one you're examining. i.e. if one sample is resampled to 48KHz (ugh!), ALL samples have to be resampled to 48KHz. And as for hearing the differences, all you need is proof! -- CatBus ------------------------------------------------------------------------ CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=29286 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
