On the matter of volume levels: All sorts of junk that makes it into the digital signal will ADD to the spectral contents (same with any distortion, BTW). Hence, getting rid of this junk will make the signal seem quieter. If one doesn't turn up the volume to compensate, the increased swamping from aucoustic room noise, and ones ears' accustomisation to previous levels -which is frequency dependent, may well, in a typical A/B, make the more distorted signal sound subjectively better than the more correct one! However, after turning up the volume to comfortable levels one might find that the "duller" sound with less distortion now sounds more natural and non-straining. -- P Floding ------------------------------------------------------------------------ P Floding's Profile: http://forums.slimdevices.com/member.php?userid=2932 View this thread: http://forums.slimdevices.com/showthread.php?t=29058 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
