The case might be that this particular player has a very special “ house sound “ you have become accustomed to and like. The Vincent DAC might be bad too ?
It’s also the case that most DAC’s are transparent to a human listener even if they measure different at some technical level they are actually both better than CD almost any of them so decoding a CD 16bit is no problem for a 24bit DAC who in practice conks out at 20-21 bits or so
( because physics) and also better than us listeners too . So it becomes a matter of features functions and quality and look and feel .
You can .
Reapair your CD .
Try DACs at home can you borrow .?
Use psychoacoustic to your advantage, hifi sellers and thier ilk use to talk about “equipment burn in” it’s actually the listener that gets “burned in” ie getting used to the new thing .
So you can listen trough the Vincent DAC for a while a week or soo and the switch back to tubes CD and see what you think then ?
