What's non-intuitive about that? Those two numbers differ by 0000000000000001, which in 16-bit audio would correspond to an incredibly small change in volume. If you don't ignore the least sig bits you get an imperceptibly small change, if you do, you get no change - just as you'd expect. It makes no difference whether the level in question is carefully chosen to make the difference look big when written in base 2. Your argument is tantamount to saying that adding a $.01 tax makes something that originally cost $999,999.99 MUCH more expensive.

He just cherry-picked a special value to make it look like a big change when written in binary, when of course it's not. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=45107 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
