Maybe it's best then just to NOT do any upsampling if this is the case - jitter be damned! Will have to look into this further this weekend... The "Raw Power" CD with DR1 might be an interesting case in extreme clipping if one were to upsample and see where these peaks lie. I remain a bit disturbed that the DAC1 would perform upsampling without *some* amplitude headroom... I really want to see evidence of this like the Ken Rockwell square wave spectrum plot between max volume and maybe -6 dB to look for harmonic changes. I might have a peek at this with my Essence One with & without upsampling enabled to see if ASUS did it right. ------------------------------------------------------------------------ Archimago's Profile: http://forums.slimdevices.com/member.php?userid=2207 View this thread: http://forums.slimdevices.com/showthread.php?t=98706 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
