You are right for a regular input, but this S/PDIF input is connected to a transformer. The transformer's primary winding (which is where to connector is wired to) only needs to see the signal from the S/PDIF coax, it does not need ground (well, the shield is connected to ground at the transmitting end, i.e. the SB or CD player). That's the nice thing with a transformer... ie. you eliminated a ground loop that way. > Regarding the electrical-to-/light conversion process, I wonder what > problems this conversion can still have in a DAC like the Benchmark. > If interface jitter (a solved problem with this DAC) and data-errors > (extremely unlikely unless the DAC is broken) are both handled, what > possible other issues from the conversion could remain? Sorry if this > is a dumb question, but that never stops me! :) Nothing bad that you can hear, but many people believe they hear a difference in sound when they compare coax to toslink. So, why don't you try it, you only need 1 extra cable ;-) cheers, Nick. -- DeVerm ------------------------------------------------------------------------ DeVerm's Profile: http://forums.slimdevices.com/member.php?userid=18104 View this thread: http://forums.slimdevices.com/showthread.php?t=52817 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
