Exactly this indeed. Recently I started using roon on top of that. That takes the experience to an even higher level. As you point out, though, it's for serious music lovers.
The main thing for me was that Qobuz is from Europe. In doing so, it aligns with my desire to have a library with my album collection and less focus on playlists. That's a personal preference, of course. Previously, I was using Apple Music. And since using Qobuz in combination with Roon, I don't want anything else. I use (for now) an apple device. How stable it runs on Linux I don't know. But so I am very curious about that 😉 ps. Roon also works with a time slot subscription.
Enjoy it! 😉
Qobuz is bases in France 😀
