Bottom line: since we don't yet understand where this artifact is occurring, we'll all keep throwing ideas at the wall until one sticks 
@robkyf
The Pi 5 is a power hungry beast compared to the Pi Zero 2 W. Regarding this, @simonb asked a cogent question. Do you have an adequate power supply for it? Preferably an official Raspberry Pi supply specifically made for the Pi 5?
An easy way to check whether your specific uSD card is the culprit is simply swap it with the card that was in your Pi Zero 2 W. I routinely swap cards among different ARMv7/v8 model Pis as I test new moOde features and try to diagnose other users' problems.
The moOde connection to your CD player is via the Pi 5's USB interface controller to your receiver's USB interface controller to your ESS 9018 DAC chip. The Pi 5's USB subsystem is different from the Pi Zero 2 W's and I suppose it's possible the USB signal timing is subtly different
Still, as I mentioned in my revised post above, I'm having no trouble playing from a Pi 5 to my Khadas USB Tone 1 board. It contains an XMOS USB interface controller driving an ESS 9038 DAC chip.
Because this glitching is semi-regular in nature, I'm still hoping we'll get to see some telltale signs in the system logs. At this point, however, I don't know what the specific error and/or warning messages would be.
By the way, what do you mean by "glitching". is is simply a momentary dropout or something else?
