A little more thought and it's obvious that you can't keep all 8 bottom bits zero. I had a bit of a brain-fart there!

I do vaguely remember that discussion now you mention it. I'm not convinced that the extremely small loss of resolution is necessarily the explanation. We all know that very precise level matching is critical to making meaningful comparisons, and that very small changes in level are first heard as differences in quality before the loudness difference is noticed. It seems to me that if you normally listen at, say, volume setting 35, and a new firmware comes along where the actual voltage at level 35 is very slightly different, then that could produce a perceived change in quality, even though the loudness seems the same. -- cliveb Performers -> dozens of mixers and effects -> clipped/hypercompressed mastering -> you think a few extra ps of jitter matters? ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=28133 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
