All CD players are kinda crap at digital. The best possible source for a digital file is a RAM Disk. Its not hard to see why, as its absolutely effortless from your RAM.
I have actually tested this extensively, and an NVMe drive is pretty close to a RAM Disk, with SSDs just behind and HDs behind them. I don't have good CD players to test but regular ones are not as good as any HD that I have heard. CD players just throw the bits, as they read them, at their DAC, or out to your DAC, while digital files have header, so the system knows what's happening.
Come on kids, I'm nearly 75 and have been tweaking my systems since the 80s of the last century. Computer noise can be pretty well eliminated by using a Pi bridge of some kind, and the Pi2AES hat is so good at this, the signal my DAC sees is very clean indeed, with almost imperceptible levels of both noise and jitter.
