I don’t think there is a consensus on MQA. Many of us who are Tidal customers (myself included) use it since it’s the only way HiRes audio is offered on that platform. On paper it’s an interesting idea…lossy HiRes which decreases the file sizes dramatically much like other more widely used lossy schemes (MP3, AAC). What’s confusing to many people is the need to have a specific MQA-capable DAC to “unfold” any HiRes audio greater than 96khz.
While I personally think the sound is nice, I think MQA is mainly a format that tried to solve a problem that largely isn’t a thing in modern households. I think most of us are listening to MQA in our homes and not on the go. As a result, the need for smaller file sizes is pretty much moot since broadband in nearly all offerings is more than enough to stream HiRes audio in a FLAC or ALAC file. After all, videos offerings such as Youtube, Hulu , Netflix and everything else stream more data to us every day and we don’t think about it much anymore. This makes competing services like Qobuz or Amazon appealing since you don’t need tricks with them to get HiRes…you get the unmolested data straight from the source.
I do think that MQA is pretty clever for portable DACs since data on cell networks is still fairly limited compared to home broadband but even that is changing with 5G becoming more popular and eventually will be the standard in coming years.
