If we had represented the original 16 bit signal as 20 bits, I assume we'd be able to slightly reduce the volume and pass to an external 20 bit DAC, without losing information (although reducing SNR - which I'm not saying is irrelevant, but in my case, I use a pre amp to set my maximum volume, and then use the sq box to adjust slightly for convenience) -- Triggaaar ------------------------------------------------------------------------ Triggaaar's Profile: http://forums.slimdevices.com/member.php?userid=1417 View this thread: http://forums.slimdevices.com/showthread.php?t=30916 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
