I had a trial with Qobuz earlier this year and was happy with how it all worked, I just wasn't in the market for a subscription service but the streaming was good and I bought a few albums in FLAC, everything was great. I wasn't delving too deep in to their library categories but did look at their KPM stuff. They were lacking in a few other genres I was interested in which is why I didn't continue beyond the trial.
You can see everything they have on the site from their download store with 30 second samples of everything, so it's easy to 'try before you buy' and the free trial of course.
