I had forgotten how nasty audiophile forums could be, especially the descent into patronisation and ad hominum attacks. Simply trying to explain what the objectives and block-level mechanisms of MQA are is impossible.

I now understand that "it would take about a week of hacking in something like Matlab to come up with a prototype of an encoder/decoder", that MQA will be reverse engineered and an open-source version will allow anyone to exploit it, and that some-one will crack the encryption (sic)and everyone will need s/w updates to load the new keys.

Of course no-one has actually listened to an MQA demonstration and come to a subjective or objective conclusion on whether it is any good.

In the spirit of Spinaltap, I would like to confirm that I am not involved in the corrupt theft of a global sport.
