I seem to recall one of the more famous objectivists that used to post here that insisted that other people look things up for themselves. I am not claiming to be an expert on DBT's, but I have studied things a bit, done some controlled listening tests (which are the basis for my DIY audio cable designs), and provided DIY information over a wide range of topics that is pretty much well accepted and taken to be valuble and worthwhile as DIY projects.
Well, I'll make it easy by providing the URL's and info here.
My AES paper is preprint #3178, "A User Friendly Methodology for Subjective Listening Tests", presented at the 91st AES convention, October, 1991. I can send a free copy to anyone who requests it via e-mail, or if you are stubbornly independant, you can purchase a copy at the AES website it is available for $5, and can be ordered from:

Follow Ups:
Proofs of an Absolute PolarityAbsolute polarity is an interesting phenomenon (wherein) those who don't hear the effect mostly doubt the opinion of those who do. (John Roberts, AES) A newly-devised test (herein called triple-blind) once-and-for-all assesses polarity audibility variously among audio engineers, hobbyists and musicians. Results decisively affirm the sensation; many trial subjects moreover testify that Absolute Polarity's palpable reality constitutes an essential addition to the audio engineering armament.
Preprint Number: 3169
Convention: 91 (September 1991)

> bothering to look.Thanks for the CV but I think you may have lost the plot somewhat. Why should I look you up? In addressing John's statement I have not misrepresented the basis of my statement and your strong promotion of cables makes clear your relationship with the scientific method.
Not that I have followed any of your links to find out one way or the other but there is nothing in your CV that would prevent you from being an unscientific loony.
The AES is a club for the audio industry and getting papers accepted at their conferences means that the organisers considered the paper to be of interest to their members (or they were struggling to fill up the programme) it does not confer any scientific merit on the contents. To do that you need to get it accepted, reviewed and published by a reputable scientific journal. The reviewers will require adherence to the scientific method which can be a big stumbling block for enthusiastic audiophiles. Even then, subsequent work may show it to be wrong but it will generally be accepted as "scientific work".
Patents also confer no scientific merit whatsoever on what is patented. In fact it is easier to patent nonsense than it is to patent something sensible because there is more competition in the latter category. You will notice that it is quite common for the wacky audiophile products like Klaus's resonating cups to claim patents or patent applications to help support the marketing.

That pretty much pegs your mind set and attitude. Now I know not to waste anytime on your replies.

Andy, you are: "Cruisin' for a bursin' " ('Grease') with such slander. After being a member of the AES for more than 40 years, I might have some criticisms, but you have just slandered (or is is libeled?) an organization that was founded to help audio engineers make better audio designs. In fact, it has deviated from that path in recent decades, because it was taken over by the Ph.D. academics, and peer review has been used with a vengeance as a tool, to reduce new ideas and to remove progressive ideas from the pages of the 'JAES'.
Is it any better in any other scientific society? I really doubt it. Politics and prejudice always seems to be part of the picture, and I don't know of any scientific society with really clean hands, or a perfect record in weeding out 'faked research', 'attempts to steal vital information' or 'active suppression of new ideas'. This appears to go with the territory of trying to make a new and better understanding of physical reality; be it hard science, or a better audio product.
When Lord Kelvin ( you know, the guy who we named the degree scale after) said "X-rays are a hoax!" in 1900, he was former President of the British Royal Society. Allowing such sloppy thinking, without proof, must imply that the British Royal Society is not very scientific either.
