Just bought the DS50U (CPU Intel Celeron 7305, 250 Euro) which had much better SQ than the more faster machine DS50U3 with i3 CPU.Interesting... . Have you tried the Pi5, which is much cheaper?

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.

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.
There is a CM5 development kit
https://au.element14.com/raspberry-pi/sc1755/cm5-development-kit-eu/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.

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)
