Dr. Moran, I think this test you used is brilliant! Thank you.
Two words: Prior art.
The Meyer Moran test is basically a straight wire bypass test of the ADC/DAC combination they used to create the CD-response bandbass filter.
Here's an example of its use from over 23 years ago:

Straight wire bypass testing was old 23 years ago!

Any chance we can see you apply this great A/D/A loop test of yours to vinyl records? Without your test there is no way to conclusively show the young folks that their preference for an LP over a CD is simply due to the different master recording that made it, or some LP distortion they "dig". [Oddly, for reasons that escape me, some recent LPs have a larger dynamic range to the CD version (due to the mastering), with some pop music, I'm told. This would also help expose that this fact is a mastering issue, and not inherent to the mediums themselves.]
The test in question has been done many times. It is fairly well known that if you burn a CD of a LP transcription it sounds just like the digital file that was originally created by the transcription process.
Yes, many of the things that people say they prefer about LPs is mastering, and it is almost certain that the rest is simply hype.
