I set a secondary system in my office with a zen mini mk3 roon core. I have already a roon license at home and It’s working perfect. It takes just a few seconds for the roon app to change core and deauthorize the other core. Obviously I only listen to one core at the same time, either at home or in the office.
My office system consists of a T+A V10 integrated amplifier with a zen mini mk3 as roon core and streamer, and my first speakers ever I bought 30 years ago ( Focal/Vieta 515 by jmlab) and it sounds amazing.
