I passed on Roon for two reasons. First, they do not have a control app that runs on Linux, even though they have server and endpoint software for this OS. My laptop runs on LInux and I use it a lot while listening. Without a control program, that meant I had to pick up my phone or Kindle, get it opened up, go to the Roon program and do whatever I wanted, then return to the laptop. That's a lot of extra steps and a slow process for pausing to answer the phone or just skip a track.
The second issue is Roon doen't support folder browsing and, after using LMS (Logitech Media Server) for well over a decade, I really missed that option. Roon, which is heavily album based, really wants you to look for music THEIR way. I think I was just too set in my ways.
If either of those two features (particularly the first one - a Linux control app) were present, I'd probably have stuck with Roon. I'm still watching to see if they make any changes going forward.
