Who has tried "TIDAL" vs other streaming applications?

Hello, I'm new to Audiogon, this is my first posting into Forums.

I enjoy streaming audio from my PC and have been using Spotify for a number of years now (college student discount to premium $5 a month). I just recently stumbled upon a App called TIDAL, that streams Lossless 16/44.1FLAC with their "HI-FI" subscription (Student $10 a month). Since I can queue up Spotify and Tidal at the same time, I was able to do an A/B and used Dire Straits Brothers in Arms. I noticed that TIDAL indeed sounds better to me but am convinced none of my family members could tell a difference. I then did an A/B with TIDAL and the actual Brothers in Arms CD, to my surprise TIDAL sounded scary close, if not just as good as the CD! This is hard for me to believe, I think I'm just trying to justify the extra cost of TIDAL on a crazy tight student budget, maybe its a placebo effect? I need to drop one of the services, but which one? I would appreciate your thoughts please... Thank you!
