Réponse de Daniel Weiss sur le fil Weiss Dac204 sur Head-fi:
"Both DAC204 / DAC205 use the same DAC board.
For the S/PDIF inputs we use the S/PDIF receiver built into the DAC chip. The DAC chip has an async SRC built in. We use that for de-jittering purposes.
As for the USB input the master clock comes from our USB interface. The USB interface is connected via I2S to the DAC chip which again uses the SRC for de-jittering.
So the USB interface may be better in terms of jitter performance – although that depends on the S/PDIF signal source. If that is low jitter then the S/PDIF input can also be very good.

Daniel Weiss"
