Sean, it's a matter of bandwidth in either case. An electrical signal can only change as fast as the fastest frequency that can travel down the cable (and this does depend on inductance/capacitance, etc. - but it's been a long time since I studied this stuff!). For an optical cable, the fastest the signal can change is the highest frequency of light that can travel down the fiber, and yeah, light in the infrared/visible range is *very* high frequency. Nothing in physics is "instantaneous" (not even photons) but you can get close! -- LavaJoe ------------------------------------------------------------------------ LavaJoe's Profile: http://forums.slimdevices.com/member.php?userid=2331 View this thread: http://forums.slimdevices.com/showthread.php?t=18772 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
