The Black Hole......

Mr. van den Hul just changed the world. His cable really transformed the stereo system.

Mr GUNFU, you didnt mention the source media of the recordings listened to. Was it vinyl? Digital at std CD resolution? Hyper bit and sampling resolution? Just curious what the source signal was, to be as effected and transformed.

Also curious if these transformitive qualities attributed to Mr. van den Hul's cable would also be perceptible in mono; was it a spatial or timbre effect?

What might be fun at your next get-together is to try mono source > switch cables > single amp > single speaker. I wonder what that does?

Except that's not what they said. You are taking once sentence out of context and then snipping it further to support your beliefs.

While it is not exactly what the authors have said, if you take the next sentence into consideration:

"However, it is possible to substitute loudspeakers of progressively lesser quality of reproduction, and to continue to repeat the tests until no difference can be heard between the different DACs."

it is inverted but very close, I'd say.
 
Maybe my point wasn't clear. In the past you have talked about consulting experts (expert food tasters, or whatever) before commencing experimental design. An expert listener could help validate the design.

Of course, there are several ways to enhance the test design, but I thought/hoped that would be obviouse given the numerous post I've written about it.
So, I only tried to describe what he intended to do, what he has done and why the experiment couldn't work that way.

But, two sets of DBT runs were done and based on the results we are able to do our own statistical analysis.

<snip> An expert listener could advise you if your equipment (amplifiers, speakers, headphones, etc.) were of a type to make recognition of cable differences easy, hard, or very difficult. How else would you know, or do you even care? If you don't care, there is still missing information about what was actually measured: differences is cables, or reproduction equipment masking effects of cable differences. Furthermore, for cables that differ in shielding effectiveness, local RFI/EMI might make cable differences more or less distinguishable at the test site than in the lab. Again, how would you know?

Again, of course, he did some pretests and based on his work (while studying) parttime in audio retail he surely was confident that the tests would corrobate his hypothesises, at least that was my impression from reading the thesis.

I’m not persuading anyone. This is your stereo. It's easier to take and try different cables yourself. I am not interested in promoting Mr. van den Hul products. Because I never mentioned the exact brand of this cable. Moreover, I myself am experimenting in this area. My friend also has cables from other manufacturers, including home-made ones. They all sound different. As for mono recordings, we, of course, listened very carefully. By the way, those experiments with cables were conducted by Russians in a California studio. One worked for the US Navy, the other now works for JBL PRO and as a result of computer simulation he created a new product for the first time in 70 years. The monophonic recordings of the 50s and 60s also sound amazing like stereo recordings. And there is also spatial information. We even discussed among ourselves why stereo was invented, if mono is not so bad? I would even say the opposite: it is strange that we explain this to you, I think you have much more opportunities for experimentation, both in the USA and in Europe than in Russia. Apparently, we are more obsessed.
