I found this talk about MQA at Chaos Computer Club Conference from december 2017 very interesting. For instance, the scientific evidence referenced by MQA is experiments conducted on barn owls and rats. First part of the presentation is a historic overview of digital audio so most SH members can skip to 15 mins in to the presentation. Don't skip the QA in the end. A fun sidenote is that @Archimago is referenced in the talk.
