Thank you for the link!

I like this paper, from the selected articles on the main page. (I saved everything from http://www.avahifi.com/root/audio_basics/ab_pdf/)

And no, I have not turned into a meter man. I am surprised in fact but not in spirit by this report of the meter man's meter man:

"The specifications and test procedures have been established and executed by those that seem to have little interest in the actual high fidelity reproduction of music at all. Perhaps unconsciously, they even seem to set up standards and conditions of test to ensure that any real differences they overlook are swamped out. For example, when I visited Julian Hirsch's facility several years ago, I noticed that his test lab was a converted attached double garage. The floor was hard, the environment was metal test benches and racks. The room had the sonic character of a grade school cafeteria. In his lab I could hear no difference at all between any amplifier or preamp he used, including ours. He had both big B&W and KEF speakers set up side by side. I had no clue which I liked better. All components that measure good sound the same - true in Hirsch's test environment - a self fulfilling closed loop."
