Latency between the input receiver and chip? I know the USB data
contains no clock info, but your comments are a little over my head.

If Gordon Rankin were here he would say:
"The S/PDIF environment is more prone to unwanted variations in the
frequency of the incoming word-clock signal, which the converter is
always trying to track. But with a USB controller generating its own
word-clock signal, the frequency remains steady."
