Convert Vintage Audiophile CD Player (Mod Squad Prism - CDB650) to "DAC"


I feel pretty confident this is not a new or novel concept, but what I would like to try to do is find a way to bypass the transport, and feed my old Mod Squad Prism (modded Magnavox CDB650 + I also have a stock CDB650) with a digital stream, and effectively use the old CD Player as a DAC.

Can anyone please point me in the direction of finding out how to do something like this?

I think the big issue with this is, it being "multi-bit", but if I knew that, I may not have been here asking the question, right!?

Thank You for posting the older CDB650 article/review. A trip down Memory Lane indeed. Back in the 80's "cd players" were everywhere for sale. I can remember seeing this model is several now defunct Department store(s).
Not quite sure if multi-bit vs. 1-bit matters? An interesting thought though.
Happy Listening!
