Hello Gary.
Some crib notes I quickly put together on what MQA really does (as opposed to its marketing claims) can be found here:
These are based on a several year disambiguation by consumer and engineers (and NOT industry insiders such as the trade publications, software/hardware supplies and/or others in “the industry”, etc.). The “MQA is Vaporware” thread over at Audiophilestyle.com has been a central meeting place for this consumer disambiguation and pushback for quite a while.
As far as hype and promise of “Hi Res”, yep I agree there are more than a few problems all along the recording/mastering/consumer playback chains. Whatever it’s real though limited value, it has been hyped and oversold. That said, it’s largely a failure in the marketplace as only “audiophiles” even pay attention to it.
