Take a look at the Bricasti M5 Network Streamer. The M5 and your Mac only need to be connected by ethernet cable to your network. Mac can be anywhere and not near your system. M5 works very well with Audirvana but you need it to connect to a DAC. Several cable formats are offered. On my set up, my Dac is built for USB so I have been very happy using it with an Audioquest Coffee USB cable. The M5 took my SQ to a new level.
2019 Mac Pro vs. Roon
I'm struggling to understand how a music server would differ from my 2019 Mac Pro (Mac Pro - not MacBook Pro - using Audirvana or Roon software) or a Marantz SACD 30n with attached usb storage. As far as the SACD 30n goes, I understand that you would lose a User Interface, but would sound quality suffer?
Thanks in advance,
