Shoot an email to the university IT department about what you're trying to do. They might have some answers. If you can stream Tidal on your Mac you should be able to get it to work on your Node X, which is an excellent choice, btw. The BluOS app is great. (I use a Node in the living room.)
In the meantime, using bluetooth to connect to the X works. If it's a dorm room, I'm betting you don't have Focal Utopias, and maybe bluetooth will be fine for now. Or before you buy anything else, you could use the X as an external dac if you want to try that.
Good luck! Enjoy the music. And thanks again, Margot!
(I really don't think switching to Qobuz will solve anything.)
