What other streaming services do you recommend besides Tidal?

Like mahler mentioned, classical on Tidal is pretty slim pickens.
Though Spotify has lower sound quality, I still find myself using it.
Hopefully, Quobuz will offer an alternative.

Yes I am waiting to see how Quboz turns out here in the USA once they roll it out.
Now I have my service sorted Tidal works well enough for me as they do have a goodly selection of rock both new and old.

I have used Napster, Spotify and done a trial of Tidal and Deezer at the premium level. Sound quality for 16/44 was the same for Tidal and Deezer. I like the Deezer interface better and at the time Deezer had many more millions of tracks but now I think they are comparable. I chose Deezer and have been largely satisfied for several years now (maybe not giving my $ to JayZ and that outfit had something to do with it). When I had drop outs I fixed it by re-positioning my Sonos Bridge to reduce router interference. Drop outs are rare but I expect the ones I do get are due to my router being on the other end of the house as the service is bomber at work.. If you log a support case with Deezer it’s a next day response but usually pretty good. Now that the exclusive Sonos (hifi 16/44 Flac) agreement is over you can get FLAC through a web app player now. I just downloaded the beta version and it works pretty nice and you can set your bit rate. Looks like some kind of browser app. I use it at work now all the time.  Deezer also announced an agreement in 2017 to support MQA soon.
