I use Qobus to stream and find it has a large and varied Classical section. It only gives wav or mp3 streams though , so no DSD or MQA but 24 / 192 downloads from it are superb and quite up to par with the sound quality on my CD player.
I have given up Qobuz because on my computer it had numerous faults the most annoying was that when listening to say a symphony that had four or more movements it would jump from say the first to the third then go back to the second and then maybe to the fifth . It would also stop or no reason at all and if you left it where it was it could start again in 2 minutes or 10. No I couldn't put up with it and when you complained about it they only referred me to the members forum . No for the money they charged it just wasn't good enough, I still haven't made up my mind who I will go to.
