I have both Tidal and Qobuz (beta). I hear little difference between Tidal and Qobuz music of the same bit/sampling rate. They both sound excellent on my system.
I listen to old school R&B/soul, contemporary jazz, and some soft rock. I do not listen to new R&B artists, old school jazz, classical, or hard rock. IMHO, Tidal has a better selection of the music I like.
I get a 50% military discount with Tidal and I like MQA. Qobuz doesn’t have enough HiRes music that I like for me to keep it long term. That may change, but, for the price difference, I’ll stick with Tidal. I only hope they stay in business .
