Based on this thread and my increasing frustration with the poor sound quality of Spotify through my Sonos I just signed up for Tidal and downloaded it and set it up on my Sonos. From the first few notes I heard, to borrow a phrase from the kids, OMG! Seriously the sound quality is amazing! Not the same catalog depth as Spotify but I am keeping it as this is the best streaming sound I have hear from an online music service! Thanks guys!
Tidal vs. Spotify
Tidal sounds better for sure. Search functions aren't as good as Spotify but if you are currently using Spotify, give Tidal a try and let me know what you think!
