what can't you find on Tidal?
"Arthur Salvatore convinced me to buy Coincident speakers "
What the heck does this have to do with the OP's question?
I am not a big fan of Classical.
Have you tried,
for streaming Classical music???
I don't know if you get Quobuz over there as I am in UK but I have it and think it is first class. When I was looking around for a streaming service I put my old stallwart in their search engine which is Charles Valentin Alkan and it came up with loads of results. For anyone new to him he was a friend of Chopin and Liszt and a phenominal pianist himself. It is said when he was going on stage to play if Liszt found out Alkan was in the audience he would get really nervous. He wrote some really interesting stuff but was not played too often because of the extreme difficuties involved in playing the torrents of notes . There are no end of supremely gifted pianists today who do play him, Marc-Andre Hamelin being a noted one.
TIDAL’s organization isn’t the best for classical for sure, do you count London as DECCA? I’ve found recordings I like and am familiar with on that label. The Eastman Wind Symphony is on there too from the MLP era, but may not be listed under that label if I remember correctly. I think there’s some Reiner/CSO there too, that’s what I would know from RCA Living Stereo.
I’m going to try Quobuz one of these days...
