I just now received this from Tidal,,,
"Starting April 10, 2024, you will now get access to our music library in full lossless, HiRes FLAC, and Dolby Atmos sound for the same price you pay today.
This is because we’re making it easier for everyone to enjoy best-in-class sound quality by combining our HiFi and HiFi Plus tiers into a single subscription tier called TIDAL."
So now I will have access to hi-res files for the same price I was paying for the lower tier. Excellent.
