Asynchronous usb for Expert 250 Pro CI?

[ogs]

Many thanks to all that took the trouble to answer!

I put A NUC running ROCK in a fanless akasa case with its Teddy Pardo power supply right next to the 250 and connected through usb.with a very good cable.The improvement was impressive.
Now I don’t need an audio grade switch with its audio grade power supply and fancy ethernet cables anymore. Only downside: volume does not sync with Roon as it does over ethernet.

If you do get the urge to tweak a ISORegen with the USPCB on that USB link could be worth a try
