Are we in violent agreement? Do digital volume controls reduce snr and dynamic range? Yes, and this should be perfectly detectable in ADM - but your results seem to indicate that it's not, which is why I'm suggesting there's a flaw in your methodology. I am confused by your statement that there is no "loss of information" because I would absolutely describe a reduction in SNR/dynamic range as such. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=60041 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
