On my high-end tube rig, Tidal does not compare in the standard 16/44.1 quality. The jazz listings are beyond belief. They must have had historians digging albums up.
I've listened to Robben Ford & Larry Carlton live in Paris. It was standard redbook but it was super good. It was easily better than the Tidal flac quality. Don't ask me why, I have no idea.
Have not looked through the entire rock catalog so can't comment. They have 40 million titles and 2 million are high res. "In Between Dreams" by Jack Johnson never sounded better. The subtleties are captured in everything. It's uncanny and best streaming I've heard.
Think the official release is later this month. Happy listening.
