Help DDC/Streamer with SDIF3/Raw-DSD out

I'm trying to help a friend, who owns an EMM-Labs DCC2 SE and CDSD SE combo, come up with a solution on how to play DSD files from his PC or laptop using his existing (btw. amazingly good sounding) DAC.
The problem is that the DCC2 SE only accepts DSD via EMM-Labs own Optilink glass connection or via SDIF3/Raw-DSD using BNC connectors.
EMM-Labs streamer would be too big of an investment for the few titles he wants to buy that are just available as DSD downloads...that leaves the exD USB DDC as the only option I could find so far and well I didn't manage to find one of those units. Diy options are ofc very welcome.

Please I need your advice diya with this unusual problem😕
 
Thanks for the input but he decided he will skip the dsd from his pc and continue to use his Matrix Spdif2 with AES/EBU to his DAC for streaming purposes and will think about somehow getting DSD into the DAC another time
