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.

@bluemoodriver,

aren’t you confounding quality of input and quality of transmission? An impact of one in no way has a bearing on differences in the other
Don’t think so... let’s see. We listened to the youtube, web-linked, and 2 Qobuz versions of what (as far as I can tell) the same performance. Can’t know for sure.  Each was sent to the same rig by Airplay at 44/16. Three inputs sounded very similar with only my daughter able to claim hearing a distinction between the youtube and Qobuz versions. All of us very easily heard a very substantial difference between them and the uploaded vinyl version. Expressed as a preference, none of us enjoyed listening to that version due to the noise, and the lifelessness (to our ears).  So I did try to talk about inputs, only.  And then wondered if the difference between a recording of a vinyl play and a digital stream can be so great, why are we worrying about wire directionality?

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 difference between vinyl and digital is really big. The digital is like McDonald’s meal, makes everything pleasant, smooth and equally delicious, but has less natural taste and not very useful.

Vinyl, especially early mono before 1970, appeals to the senses, it is always different, like home cooking, it can be unsalted, or under cooked, but it feels like a natural product, the pulsation of life for which you can easily put up with clicks and interference.

But there is also shellac, which appeals to the senses even more strongly. Recordings at 78 revolutions will be easier to compare - the experiment will be approximately all other things being equal, there were no tape recorders then and everything was written directly on the matrix. The difference here is more obvious, hope this tells you more.
