Interesting... . Have you tried the Pi5, which is much cheaper?

My Pi5 with Ubuntu 22.04 and SO1.3 beat the Antipodes S30, to my ears. But, my friend still preferred the S30 because it was closer to what he was used to.

I don't have a Pi5,but tried Pi3 and Pi4 some years ago. Found x86 always much better.

Volumio, Moode etc. are not as good as SnakeOil on Pi5, Pi4, so not surprised that you prefer x86 with SO.

That's true, but I also compared SO on PI against x86. May also better (SQ has more body and dynamic and is also cleaner) because of the power for my PC comes direct from the car battery vs linear DC/DC IC for the PIs. I have different SSDs for OS (SATA) and music (NVMe) as well in my PC and very fast RAM.

.....
Perhaps some audio maker can donate a decent CM5 based board for me to play with and I can attempt to see what tweaks are available in software.

I have yet to come across a CM5 based audio player.

There is a CM5 development kit
https://au.element14.com/raspberry-pi/sc...dp/4575935
(No idea of differences between EU, US, UK etc versions)
Trying to understand why the CM5 is better than the Pi5. Is the limitation the existing I/O board? And should be replaced by a dedicated audiophile board?

Well, FYI, if one would like to run Roon Server in SO, Roon Server requires a x86_64 CPU. But Roon Bridge embraces both x86_64 and arm CPUs. Shy

A CM4 audio player may well be hot swappable to CM5 as the pin-outs are largely compatible.

A RPi5 is an all-in-one general purpose computer. And a CM5 is more like a brain, it needs to be part of another board to become a compute unit. So if we a board that's specifically designed for audio, adding a CM5 to this board could well make it sing (as the CPU on the CM5 is a lot faster than the CM4 CPU)
