The Contour System – Directional Wiring of Audio Parts

Hi guys!

The topic is about subjective homemade research of conductors directivity. I know most people don't believe in such phenomena so probably the story is not for them but for those who find it unbearable to listen to imperfect sound of chaotically directed wires and components.
As for me, I hear direction difference distinctly. The matter started from interconnect cables quite long ago, after a while I added to my research inner wiring of loudspeakers, then discover the importance of mains cables direction. After all I decided to find the directions of all the wires and components of my pretty vintage DIY tube mono SE amp and after everything had been done I drew a resulting schematic and wrote the article. It was in 2005, I have translated it in English only now. Hope you will find the article useful or just enjoy it.

If you can't hear it then it doesn't matter. To you. 

As for how it sounds, scroll up, he described it.

From the article: “Subjective measurements can be considered reliable if one expert or several experts in a blind test have estimates repeated in, say, 80-90% of cases.”

So that’s the pass mark for directionality having an effect. Any results?

Also, as the Audioholics guy is saying just now on his video, the differences between speaker cables measure at below 0.06dB.  Utterly impossible for the human ear to detect. If one cable to another has so little effect, will turning the same cable around have the 10x greater effect needed for any audible difference to be heard when blind?  Really?

Anton - you set out the pass mark, you’ve done lots of work, so what was the result? Is directionality easy to hear as MC says, to the extent of 80-90% correct identification in blind tests?

@Millercarbon
Once having done all the work to map and sort you probably could build an amp that would far outperform what anyone would be able to get from the same parts any other way. Have you built complete amps for sale? Or is this more of an intellectual pursuit?

Thanks for the good, Millercarbon.
I make no amps or anything else for sale, all this is just intellectual pursuit, as you said.
