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?

hmmm.... and imagining a/the possible 16bit/44.1mhz, I actually Google'd "TDA1541 4x oversampling", and found an interesting read... https://www.audialonline.com/blog/another-story-about-tda1541a-384-khz/

OK, this is getting depressing. I have been working with Ken (by referral of Steve and Patrick (SMcAudio), and casually with Steve by email, and he says it is not practical, and I am not the first person to request the mod.

Anyone else with any thoughts?

Hang in there. IMO, Steve, should have never quit making / modding CD players?  Clearly, there is a market for us physical discs Audiophiles.The CDB 650 is a stone classic.
Happy Listening!
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!?
