Hi Charles,
This comment from you is interesting: "My understanding is that the MQA encoding process "corrects" ('de-blurs') errors in the existing digital file created by an imperfect A/D converter."
As a so-called "end-to-end" process, my understanding that the "correction" wasn't done in the actual encoded file but, rather, at the end, in the DAC itself, along with adjusting for imperfections in the DAC.
With that in mind, if, in fact, they are correcting the original file and that MQA file has been modified for A/D imperfections then the the entire thing is even more lossy than I first thought. First off, as you mention, the lower bits are gone and some compression goes in to getting it all into the 24/48 constraint they are using. Then, if a process that corrects for timing of the A/D was applied, well, that plain and simply alters the original file. Just one of those MANY questions I had (and have).
