Get the MacMini out of the picture by buying something relatively cheap like the following.

It is ROON READY. It is an Ethernet-2-USB converter. Some call it a Digital-2-Digital converter. I use the lower model, the microRendu, and it isolates the computer from my DAC. A used microRendu can be had for $400-$500.
Computer Audiophile just named the Rendu products as the digital product of the decade.
