For over $2K, I think I would try this first:

Ethernet is the best current solution. You can use Roon/Tidal or even better Minimserver with Linn Kinsky if you don’t use Tidal.
You will need to get Ethernet CAT7 cables, a EMO systems EN-70e, and a grounded LPS for your router like the Sbooster, but even with all of these I think you will be under $2K with the UltraRendu.
The other thing that this does is eliminate all of the tweaks that are necessary with USB to get superb SQ.
