Spotify Premium vs Tidal ... opinions?

Tidal all the way. Spotify does have a greater selection (not that I really find Tidal lacking... an album here and there, but definitely not a dealbreaker), but the sound quality just isn't there.

I signed up for Tidal with MQA, it is awesome. I have many HDTracks 24 bit recordings (use JRiver) and Tidal MQA for same sounds  just as good. Please use the service as I don’t want to loose it!

I have both. 

Tidal is great if you really want to hear the absolute best sound quality, but Spotify sounds great also.  There's a difference in sound quality between Tidal Masters and everything else on both services, but "HI-FI" on both is supposed to be "CD quality". 

That DAC is a few years old, no?  It's not going to support MQA through Tidal.

Tidal is tipped towards hip-hop, R&B, and other new artists.  I think you'll find a lot more in the way of playlists and "stations" on Spotify that caters to the type of music you enjoy.  You'll be able to find most of the types of music you mentioned on Tidal also, it just won't be featured on Tidal. 

Unless you have "golden ears" and plan to upgrade your DAC, Spotify might be the best choice for you.

'Tis a problem.I love the recommendations that come out every week on Spotify for me, but having just set up my streamer (Cambridge CXN) for Tidal, the sound quality is just better. Rest of system PrimaLuna Dialogue HP with KT 150; Vivid Oval 1.5 and JL E112 subwoofer with pretty ordinary cables.
Hard to give up finding new music, but prefer the sound out of the Tidal which is also easier to control from my phone or PC.I didn't think I would hear a difference in sound but I really do. It's not the cost of the Tidal, it's just the introduction to new music.
