“MQA is a philosophy”..John Stuart

There were many attempts to improve sound, like HDCD or SACD but all pretty much failed.  They had one thing in common - a strong copy protection.

Myself, I don't care for MQA since I don't see sound quality limitations of existing media.  I have few CDs with breathtaking sound proving that the format is not the bottleneck  - at least for my old ears.

@jon2020,

“the broader issues that MQA brings to the entire music industry and home reproduction”

What do you suggest we should do to save the industry and consumers from the evils of MQA? Do you think constant bickering on audio forums is going to deter the forward progress of MQA? 

There is no point engaging with someone who is actually initiating the bickering.
This discussion has been pretty civil until THE bickerer pops in.
So, kindly move along now. You know who you are.

My friend, we hear all the time politicians telling us that robotics and automation are the way of the future and that as a nation, we don't need most of the jobs that employed millions of Americans over the past half century. People "need to be retrained for jobs of the future" - so they tell us.
The same can be said of the "music industry". We don't need large corporations making copies of music recordings and selling them to us with large profit margins that made them rich - like in the old days. Technology has essentially made the big record company executives and their profits - extinct as a species. Time to move on and try to make boat loads of money for doing nothing in a different field. To quote some of our favorite liberal politicians - "those jobs are gone forever".
