The biggest beneficiary of MQA besides its owners is Tidal. Because MQA files are much smaller, they require far less hard drive storage. I agree with those who’ve noted the technology is at least ten years too late.
Having compared Tidal MQA files and Qobuz high res files of some of my favorite albums, I canceled Tidal and kept Qobuz. I have had no trouble streaming the far larger Qobuz files even when my Internet service was only at 150 mps.
