Any Sonos device with a line in, Port, Amp, or Five, can be used to connect your turntable to Sonos.  If you only want turntable, no additional speakers, then the Port is the best/cheapest option.

You can add Tidal through the app, yes.  Just go to settings then services and is pretty straight forward from there.

Wow that was quick, I forgot to mention that i wanted to plug in a set of Sennhieser direct connect earphones occasionally. How would this work now. Cheers
