@dr-john Give ROON a try and put the ROON Core computer in another room. I have my ROON Core server (a $500 PC) behind my office door next to the router. I have set up the computer to automatically boot up at 8AM and shut down at 2:30AM each day. I can stream only during those hours (need some sleep too).
If you do not have Ethernet near your stereo, then you can use a $75-$150 PowerLine adapter to stream the music bits on the copper electrical wiring of your home. This will get your music to your SimAudio Mind2 DAC on a wired connection. Which I prefer over WiFi.
I use the PowerLine method to connect my Livingroom and bedroom gear (ROON READY Endpoints) to my ROON Core. The office system is a direct Ethernet connection. Both methods of connection, PowerLine and direct, sound great.
The only caveat being that the ROON Core should be on the non-PowerLine side of the home network. This was an issue for me when playing hi-res streams from ROON. When I moved my $500 Core server to the faster side of the network all hi-res content was streamed perfectly to the ROON endpoints.
If you do decide to try what I am recommending, then the very best sound for your DAC will likely be on USB. I am assuming the Mind2 streams on Ethernet. If I am correct, then I would recommend a Sonore OpticalRendu. There are a few cheap ways to convert the Ethernet to Fibre Optical. You then take the fibre into the OpticalRendu and from the OpticalRendu you go by USB into your DAC. The glass of the Fibre cable will kill most of the analog noise that can get into your DAC. So, who cares how internally noisy the Core server is or where it is located.
BTW - your DAC is ROON READY. the highest level of compatibility. Mind2 via Ethernet streaming and the OpticalRendu is also ROON READY via USB streaming.
