Default adding digital input to a YBA CD player for use as a DAC ?

I have a YBA Lecteur CD player that sounds amazing. I've never heard a 'modern' CD player or outboard DAC so I don't know if the DAC in my CD player sounds so good because it's the only one I have, or because it really does sound good. Anyhow, it does not have a digital input. I'm wondering if it's a big project to add a digital input to this thing so that I can use it as both a CD player and an outboard DAC ????

In the absence of a service manual it'll be a very daunting project.

Since CD players are by design clock masters I reckon your best bet at getting a solution is to implement an async USB interface - that way the player still gets to be clock master. Any other interface (S/PDIF for example) it has to be a slave and that's fraught with extra challenges.

I emailed YBA for a service manual - no response. Perhaps not surprising but I agree, it's not a sensible project to undertake with full design details.

How about I put an LED over the CD drive photo-detector and feed it with my digital signal so it 'thinks' it is playing a CD - ?!

How will you create your digital signal? The laser doesn't read S/PDIF off the CD.

I'm not serious about doing that, but I could imagine that somebody handy with FPGA's could arrange something.
