MQA is an extra chip to make your gear do what it could already do. If mqa works as well as possible, it will sound exactly the same as if they had just trickled double the data.
Netflix streams 42 times as much data as a 44.1 audio stream. Oh wait, that's if the stream is uncompressed, I forgot to flac it to roughly 60% at the end.
There's nothing a server can do, besides doing nothing, that is easier on it than streaming audio files. Especially if they're compressed at all.
People who compress never want you to find out about it, though. People who charge double for streaming audio must want someone else to do it. Then there's mqa, who wants to compress on top of it, with a name they think will sound better than higher resolution. Then Tidal charges double and hires them.
