There is no need to argue if MQA is good or bad. Like others said, make your own choices and pick what you like to listen that’s all. To me I don’t hear any difference between Tidal and Qobuz. I joined both and decided to cancel Qobuz. They have less selections compare to Tidal.
Let me give you one example, for those of you have Tidal.
Go search Grant Green, you will see the two albums called "Idle Moments".
One is MQA , and other one is regular.
Hear it yourself, I found the MQA version has more separations. The other one is little flat.
You can compare them and easily tell the difference.
