I would also be concerned if I was going externally with the signal. However, the SPDIF output is hardwired to the X03 which reclocks the signal and sends it onward to a RAKK DACC, again hardwired. The RAKK DAC uses an input transformer (so no inductor needed I feel) and then a CS8416 which can accept full logic level signals (so no resistor divider needed in the cicuit either). I will post the results when I get a chance to do some proper listening and jitter tests -- Jitterbug ------------------------------------------------------------------------ Jitterbug's Profile: http://forums.slimdevices.com/member.php?userid=4955 View this thread: http://forums.slimdevices.com/showthread.php?t=32761 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
