Adding MicroRendu between Mac Mini and amp

This discussion might be helpful, where the benefits of having and endpoint, vs using the core as an endpoint, are explored:

I moved my MacBook core out of the listening room to get rid of the fan noise and the whir of the external hard drives and have not looked back. Not sure about the pure sonic benefits, but the background noise was eliminated without any loss of quality going to a RPi with a Hifiberry Hat.
