Thumb5's system

[baddog]

A quick update: I've been trying Roon Server running on the Mac Mini via AIR to the D440 Pro.  AIR has been a bit temperamental - which seems to upset Roon more than I'd expect, and is more awkward to put right on a headless machine - so I'm trying plan B and using the USB connection instead.  So far, so good.  Not sure I can hear much difference, if any, in sound quality, although I haven't been listening for it (rather enjoying the music!).

I am interested in how AIR is being temperamental on your Mac Mini when using RoonServer. I have been running that setup since AIR3 came out and have not had any issues. I am using ethernet not wireless in my setup. Mine is headless as well, hit button to boot and AIR and RoonServer start properly. Shutdown either via button or by remoting into the Mac Mini.

Not saying it isn't acting funky on your system, just curious as to what the funk is up....
