Ok, now because this has been brought up, I am required by local law to mention a very big problem with MQA.

Stomp!
In short - never use MQA and I suggest avoiding any services that offer it. It’s an attempt to abuse the community with a bad product that not only reduces audio quality (and lies about it), but it also tries to hook people on services that require endless subscription fees to continue using. It’s a bad egg all around - don’t eat bad eggs. 
And never pay companies to abuse you.
