Well yes but...
In my setup, I have 2 coax cables and a TACT rcs between my sb3 and DAC
- plenty of opportunity for jitter to be added to the low levels coming
out of the SB3.

Also, the whole point is that not much jitter is added between the
spdif socket and the DAC chip...the fact that there is  a PLL en route
is neither here nor there.
