Currently have one Mac Mini as the Roon Core, and a second Mac Mini as a Roon Bridge (its only role). Both are wired into our ethernet network at home.
(FYI - I have a couple spare retired Mini’s from work, so it’s no big deal to use them for this.)
Anyway… I wonder if it’s overkill, and could just use a $15-20 Chromecast audio dongle as the Roon output to the Sprout100.
It supports 24/96 audio, and it has an optical/toslink digital output.
