My guess is that they could come from a wide variety of places that we routinely ignore. I have no figures to back up my suspicions. It's just that over many years I have consistently found that balanced connections sound cleaner than unbalanced, even using short cables.

(in an unbalanced design) I think it's dangerous to assume that grounding is foolproof. Ground planes on circuit boards do not have zero resistance, and even star earthing isn't going to get every ground to precisely the same potential. Mains earths are rarely perfect. People around here obsess over ludicrously tiny amounts of jitter and minuscule resolution loss through digital attenuation, but I would be very surprised if the kind of inaccuracies caused by imperfect grounding weren't very significantly greater. -- cliveb Transporter -> ATC SCM100A ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=82122 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
