I did some tests ages ago of a Topping D10 USB DAC on Windows and Moode:
Windows 7 - Foobar2000 with Asio Driver on a Fujitsu laptop
vs
moOde 4.1 on a Raspberry Pi 3B
I played back some sweeps, pink noise and music and recorded the output with an RME Fireface UFX at 96 kHz.
I couldn't easily blind-test the setups, but I didn't notice any audible SQ differences between Windows and Moode. However, looking at the recorded files in audio software I did notice that the RPi setup had slightly higher mains interference (but still very low) and quite a lot of ultrasonic "chatter" above 30 kHz (in this case interference from the nearby laptop). It seems the RPi is more prone to EMI but it should be inaudible.
In short, the only differences I could find were hardware-related.
