Yes, there's the Tidal app or download and that provides the first layer of MQA magic. Nothing else is needed. To get the absolute grande experience (the audiophool experience) there's equipment to buy.
But for the first level of MQA bliss, the app provides the magic.
I shall hold my peace on the JZ ownership and the hip hop and rap megastars feeding on the carcass of the music market. That wouldn't be helpful.
That wouldn't be conducive in helping you experience Tidal in all its MQA glory.
When you get the app set up (nothing to that except preferences etc ) and your HDMI cable plugged in, you just need to search out some music. For Tidal, they designate the MQA files with a capital M sitting out next to the file names. I can tell you Sheryl Crow's new "Be Myself" is an MQA album. You can also search just for M music I suppose. You may have to search a bit to find something you like that's available as an MQA or M file. The catalog is a fraction of Spotify. I don't know how robust it is by comparison percentages, but Spotify has pretty much every title (although not every title in 320kbps). Tidal's catalog is smaller but has some very nifty features.
One of the Tidal features I did like very much was the extended liner notes on every song. Every song has a complete set of details attached to it. Very slick feature. Of course older music that never put those details out doesn't have spit in those notes. But, new music made with digital in mind does have some interesting stuff there. Much better than Spotify in this regard.
