In the latest Stereophile, John Atkinson briefly reports on a presentation from the most recent AES Convention in October of this year; a meta-analysis of blind-testing studies which suggests that even under those conditions (i.e. blind testing) listeners can reliably distinguish hi-res digital recordings from CD quality recordings. I don't have the abstract to read, and I don't know when or if this analysis will actually be published; nevertheless, I think it deserves mention in this forum.

I just spent 15 minutes searching AES but found nothing. It may be there but it takes a lot of work to find this without paper title and or author. I did find this:

"This workshop focuses on past measurements and future potential in perceptual evaluation of high resolution audio. Past attempts to assess the audibility of higher resolutions (beyond 44.1 kHz, 16-bit) will be summarized with an overview of results, but the focus of the workshop is on testing and methodology itself. Discussion will include the problems and pitfalls of listening tests and demos and how they might be overcome. We shed some light on the psychoacoustic justifications behind the results of previous experiments, including what is known and what is not. We discuss issues in evaluating quality and perception, the structuring of tests, configuration of the testing environment, and analysis of results. Attention will be paid to the choice of test material. The talks will be supplemented with a demonstration, and we intend to engage the audience with lively discussion."

You think this was it or something else?

That was the description of the workshop. The author is Joshua Riess (or Reiss?), a member of the AES Board of Governors.

Ah. Unfortunately there may not be a transcript of that session as it was a panel discussion. Here is the list of panelists:

W20 - Perceptual Evaluation of High Resolution Audio
Chair:
Joshua D. Reiss, Queen Mary University of London - London, UK
Panelists:
Bob Katz, Digital Domain Mastering - Orlando, FL, USA
George Massenburg, Schulich School of Music, McGill University - Montreal, Quebec, Canada; Centre for Interdisciplinary Research in Music Media and Technology (CIRMMT) - Montreal, Quebec, Canada
Bob Schulein, RBS Consultants - Schaumburg, IL, USA

Maybe they put the audio online later.
