Correct, the reason is actually that the ethernet link is asynchronous to the DAC clock. mwphoto Wrote: > > 2) within the SB itself using the SB DAC jitter is not an issue because > the > DAC is so close to the chip that is streaming the digital audio.

This is actually quite a simple mod on the sb side, but not necessarily so simple on the dac side. -- bludragon ------------------------------------------------------------------------ bludragon's Profile: http://forums.slimdevices.com/member.php?userid=1530 View this thread: http://forums.slimdevices.com/showthread.php?t=19636 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
