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.

No amount of wire fiddling is going to clean that dull and noisy vinyl ...
Agreed. If an LP sounds "dull and noisy" then something else is amiss, e.g. dirty disc, bad or worn pressing, worn stylus, improper setup ...

The lay audiophile does not have access to this kind of equipment thus is flying blind. It is easy enough to build AB switch boxes. I'm surprised nobody sells them.
They are available from multiple vendors. Van Alstine's has been one of the more popular - it's probably still available even though it doesn't seem to be on its website now. It's not just a switchbox, but a true a/b/x comparator. The Manley SkipJack can also be used. WireWorld makes its own box solely for the purpose of evaluating cables. 

I've long that it odd that the measurementalists who claim cables can't make a difference don't seem to avail themselves of some of these tools.

Differences in SQ can only be confidently distinguished by properly run blind testing.
Blind testing certainly has its place in audio - although not so much for the typical audiophile - but this statement is completely false. Those who insist on blind testing usually cite "placebo effect" or "expectation bias" as justification for their rather odd belief system. Those are very real mechanisms, no doubt, but they are not absolute. Placebo effect will not cure cancer. No blind testing is required to distinguish between extreme examples of audio components, nor is it always required to detect one that is malfunctioning.
If you are not testing blind, your results are personal and subjective and therefore not useful.
You’d be better off speaking for yourself rather than for others. You may well indeed require blind testing to know how something sounds, but that’s not a universal trait.

So, @clearthinker, please tell us about your blind tests. How were they conducted, how many test subjects, what were the results?
