You have to have an Apple device to stream high resolution. Spotify has apparently not delivered better sound yet, when comparing my Spotify premium to my Apple Music lossless, the quality is clearly better with Apple.Probably. I refuse to use Apple products because of their walled-garden lock-in and their monopolistic business practices.
Spotify is MUCH more open, with excellent APIs. The Concertmaster web app doesn't appear to support Spotify Connect at this time, but Spotify has a beta API for doing just that, so hopefully it will be integrated at some point. Spotify has promised a HiFi lossless tier sometime this year, so looks like the stars may be aligning for an excellent Primephonic alternative, including on a Mac.
compairing Apple lossless with TIDAL, they sound the same, I cant hear any difference.
