For high quality sound Qobuz is number one ...
+1
... and Tidal is number two. There are no others in the category.
I am not so sure, @ghdprentice. Apple claims lossless audio of up to 24/192 and the interface looks excellent. The whole platform is really designed around classical music, which has always presented search and database challenges because the genre is not built around song/album/artist the way most popular music is.
Apple's biggest hurdle for audiophiles is going to be its app's connectivity. One possibility I see is that the app runs on Roku. I already take HDMI digital audio out from my Roku and into my DAC, so I may take a free trial sometime. But I'm just so pleased with all my sources now, including Qobuz, that I'm in no rush.
