If it's useful for anyone else.
I am using one of these successfully:
Here's an image
It's a Cirrus Logic based cheapie USB 5.1 soundcard.
Now the ADC/DAC in it is poor quality (and has an aggressive high pass rolloff for low frequencies unless you replace the in-line caps)
However the SPDIF input seems to be straight through. It sounded identical to me, compared to a FLAC of the same CD ripped.
the chain is:
Digital transport (e.g. TV or CD player with optical out) -> USB 5.1 SPDIF (above) -> USB -> PC (running CamillaDSP with USB capture and DM7 output) -> DM7 -> amp/speakers
