Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

Well, that's exactly what I'm trying to talk about (except that EMM Labs uses two return cables instead of S/PDIF for the returning clock and data, avoiding the obvious problems with jitter in S/PDIF decoders.)

Note the legend in your diagram (nice diagram, BTW), especially "dirty clock". The jitter I'm talking about is the dirt on the dirty clock and S/PDIF signal. Note in particular that your diagram is correct in that the input to the DAC isn't the clean clock: it's been polluted by the dirty clock and data coming into the reclocking circuit. That pollution is caused by things like local ground bounce that I was trying to talk about. See the links to various papers in the posts below Christine's post.
