I don't know a great deal about Spotify, as I've never used it. I understand what it is and how it works, but I've been wondering what Connect is supposed to do. After a bit of reading, it seems that Connect is required in order to stream Spotify wirelessly to a speaker system. It would appear that the speaker system in question needs to be Connect compatible.
Tidal I would imagine is going to be much the same. It would appear they have signed a deal with a German company, so maybe at this time only speakers released by this company will have the ability to play Tidal wirelessly.
