The typical digital XLR output is AES standard...110 ohms. Are you sure that the output is XLR/spdif?
Usually a XLR AES transformer is used to convert AES to spdif coax. But if your output is truly a balanced XLR spdif, then call PS audio or Google XLR to BNC 75 ohm adapters or cables.
The great thing about your setup is that the PS transport samples the CD to an internal buffer and then outputs it. The Chord DAC also samples the incoming data to a buffer and then reclocks it. That's why I think coax will work just fine.
