How Is MQA Fareing?

Thanks for those thoughts. Lately, the only info I found was this: https://www.stereophile.com/content/mqa-tested-part-2-fold

This week, at Mobile World Congress, wireless heavyweights will talk about the emerging 5G standard ...that looks like it will deliver 10x current bandwidth.  
So by the year 2020 we will be able to stream lossless 24/192k audio to our phones.
Any impact MQA makes will be short lived.

A comprehensive, technical and balanced treatise.
Kudos all round to the author!

Here's another man's opinion. Note: Very long

Good article, the author seems to be without a strong technical background (gets a few things wrong or confused and some misunderstandings) but overall a good critique with solid concerns about MQA. A bit wordy. TLDR.

Here is a technical summary in short version:

MQA is all hand waving BS and has absolutely no sound technical basis. It consists of manipulation of the audio file to give up some bit depth (loss of about 6 bits resolution) in exchange for a higher sample rate (a portion of higher sample rate data is buried in the lost bit depth data). Lots of hand waving to say that this is a beneficial trade off which is dubious as the greater bit depth has proven benefits (dynamic range) and the benefits of ultra high frequency stuff is useless or dubious at best. As anyone can see - you are almost certainly better off without this lossy form of compression.
