Trouble is, this good effort does not address the other problem, which is that the audibility of various differences varies tremendously. A good example is jitter. High measurable jitter, particularly if measured by means of taking time-aligned, gain-aligned, and frequency-response corrected measurements, can be pretty innocuous sonically. A good example of jitter tolerance would be taking the difference between LP playback and the master tape used to make it. The measurable differences are huge, but as we know many listeners do actually prefer the distorted, noisy sound, or at least tolerate it. ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=106519 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
