I listen to jazz on Tidal constantly and find the catalog very good if not as deep as Spotify. For sound quality it's no contest I was sick of Spotify's sound before I even knew Tidal existed, Pandora Premium sounded noticeably better to me back in those days.
Moving to Tidal
I have a Cambridge CXN and have been using Spotify for the last year. Just spoke with Cambridge and got the niggles out with Tidal (simple, reinstall the app and reload the streamer). Clearly better sound on the Tidal. I love the "Release Radar" and artist radio on Spotify. Not seeing anything similar on Tidal. Any suggestions or should I keep some Spotify (cheaper subscription) and look for new music there?
