Connect 2 USB-B, 1 pair Balanced Phono and 1 coax input to an Integrated Amp/DAC

I have an Integrated AMP with built in DAC that I love- Daniel Hertz Maria 350. It only has 1 USB- B and 1 Coax input plus 3 RCA analog inputs.

I need to connect:

Roon server via USB -B

Mac mini via USB- B

Pro- ject R2 Phono stage -prefer Balanced inputs but can settle for RCA 

Bluesound Node - N130- can connect  via coax

My biggest challenge is that I NEED an additional USB-B connection for the Mac Mini. I use this for You Tube music video so if I could figure out a way to handle the video signal as well as audio for Mac mini that would be best. Remote controlled Volume would be very helpful too. Any thoughts/Suggestions are appreciated.

It is possible to turn Mac into streamer so Roon will see it. Then you only need to connect Roon. OR turn Mac into Roon server? Do you really need two computers?

I was using my Mac mini as my Roon server exclusively. The Mac seemed to produce a lot of noise and I choose the dedicated Linux based music server/streamer in an attempt to get better SQ. When connected the RoonServer does produce beautiful SQ. Now I have the issue of 2 USB connections. I will likely try a USB hub next and if that doesn’t work I may jettison the music server and go back to the Mac mini. I’ll then seek suggestion on how to quiet the Mac mini. If I turn off ALL background processes, connect a liner poster supply instead of the SMPC, and figure out how to work around the apple midi settings that might help. This is the exact core function of Audirvana . I guess I could switch to Audirvana instead of Roon if that is the only way to quiet a Mac Roon server.
