Nearly every time SD changed the firmware lots of people heard the difference. Quite remarkable, considering most of the revisions didn't affect the audio chain. > You seem not to appreciate the difference in inaudibility between truly > random noise, and other low-level distortions - if dithering is applied > to the rounding process, you should be able to make the noise random, > and therefore I'd expect it to be inaudible. However, non-random > distortions even at very low levels can definitely be audible. Please provide evidence that anything (-regardless- of its spectrum) at -140dB is audible at ordinary listening levels. -Maybe- with your ear on top of the tweeter, nothing else playing, and the volume cranked you could hear something. > Published measurements do not tell the whole story.

As the manufacturer and marketer of a SB modification you would say so, wouldn't you? -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=45561 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
