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.

Ausaudio, maybe it was in the USA, but I'm from Russia. Our first digital telephone stations appeared in the 1990s, and then only in large cities. In St. Petersburg (5 million people) back in 2000, some stations did not understand the tone set, that is, they were still relay, purely analog.



The person who posted that comment on telephones was from the USA.


You are doing nothing more than romanticizing a bygone era. Old analog PSTN was pretty awful, almost all aspects of it. Low sensitivity microphone, low bandwidth, very low signal to noise.  Modern communications, especially some of the Internet based voice platforms are so far ahead in voice quality a comparison is laughable.


You were evaluating the liveliness and "fullness" from 300Hz - 3000Hz.  Think about what you are implying.  You are honestly comparing that to what is typically 50Hz - 7KHz, often with much better SNR, if not even wider bandwidth?

If people have qualms with the concept of directivity, I suggest they turn their fuses by 180 degrees. If they can‘t hear a difference, two options are available:

1. get better equipment
2. get better ears

I guess he's old enough to know what the U.S. analog phone line sounded like.

There is a bit of romance, of course, the grass was greener, the girls were younger )). But no more than that.

Yes I am. I see that you can't believe that a less technically advanced device can sound better. I guess all the cables sound the same to you and have no direction, right?

@anton_stepichev,

Hihi, you‘re dead on the money and I am loving it....
