One of the big improvements of the Raspberry PI 4 was to separate the USB bus from the ethernet bus. Why?... Because of the noise of the shared bus. PI 3 was still able to backup your hard drive as a computer bit (a switch) isn’t as prone to noise as an bit converter.
i haven’t tried a PI 4 but requiring a fan because the extra heat it produces made me go a different way.
The PI2AES was a I2s interface that blew away some of the top streamers unfortunately they aren’t being made and probably will incorporate the technology into a much more expensive products.
Here is a post on how to improve the USB signal for sound reproduction and it works for me.
Not a robot but I do dream of electric sheep
