and the other AES paper is that if a master recording is made at a high
sample rate, then any reduction of sample rate for commercial release is
going to result in a reduction in quality. So why not, then, release the
recording at the same sample rate and resolution as the master? The end
user will then know that he is getting the full sound quality.

It's funny how as audiophiles we are encouraged to use high quality recordings of classical performances to differentiate between audio components. But in this case however we are expected to believe the equipment in both recording signal paths (operating at different rates) and a DAC (also operating at different rates) in the playback path are sonically identical when presented with such challenging inputs and that the only differences audible should be attributed to the resolution of the created recordings.As someone who believes that these kinds of musical performances actually may present great challenges to audio performance I'm not really sure what I should takeaway from this kind of test. I guess my problem is I don't have a bias so I'm kind of just left hanging here without anything to takeaway.
I'll go away now.

No, you are not expected to believe that at all. If the ADC and DAC sounded the same operating at 44.1k and 88.2k rates, then the results would have been null. The result was that recording & playback via matched signal paths operating at different sample rates sounded different.
It's hard to believe you don't understand the point of this experiment. It's like you're arguing just to argue. Your posts are baffling.
" If the ADC and DAC sounded the same operating at 44.1k and 88.2k rates, then the results would have been null."
If that were the case then one could question (and many would including me) whether the components were capable of resolving the differences - it all seems to depend on what point one is trying to make.
" It's hard to believe you don't understand the point of this experiment. It's like you're arguing just to argue. Your posts are baffling."
LOL - as if understanding the point of an experiment requires one to accept the conclusions/suggestions others have made based on the results of it.

Such a concept would have been unfathomable in the analog tape days or in the earlier years of digital. Today, it's a non-issue in terms of cost or deployment.
"So why not, then, release the recording at the same sample rate and resolution as the master?"
The 64,000 dollar question John.
