I was a late adopter of Roon, but I would not go back at this point. Having said that, if the only digital source you have is Qobuz and you only listen on one system, then perhaps Roon isn't for you.
If you have multiple sources, then Roon is fantastic. I have Qobuz, Tidal, and a large collection of music on my network and 4 systems. Roon allows me to bring all the versions of a song or album into one interface and makes it easy for me to choose which system(s) to play it on. It's also great about making suggestions for new music I should try. The Qobuz interface is pretty good, but Roon will take things to another level even if that's your only source of digital music.
