I was using squeezbox for a long time and as streaming of Spotify or Tidal is not working well with Squeezebox I decided to establish a Volumio setup. First I built a volumio setup with a raspi and a hifiberry digi+. The sound was pretty good and usability was also very good. But I was facing some problems with stability. Every now and then I had drop outs and sometimes it stopped without a visible reason. I had to restart the session. Every now and then it doesn't respond any more. I had to unplug power supply to reboot the whole thing. Thought it was a raspi problem therefore I decided to buy the Primo. But the problems are still there. I run Volumio for more than one year, but now I'm testing the roon setup. After 3 days I am really enthusistic with it. Concept and usability is much better and by now I didn't face any stability problems.
