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.

Do you also have a sensitivity to absolute phase? I’ve often wondered if there is a correlation with cable directionality, but either my ears or my system isn’t up to the task.

In my opinion, if there is any correlation, then no one can accurately determine it. The fact is that it is impossible to set up a correct experiment here, with all other things being equal.

To determine the alleged effect of the absolute phase on the sound, you must assemble a phase inverter device that will contain a number of radio elements and wires including a bypass switch for comparison. During a comparison test when you listen either through the phase inverter or bypass it, the difference in sound will naturally be heard, but it is impossible to interpret it unambiguously, since the phase rotation device contains many parts and conductors that randomly affect the sound.

The people who initially experimented with the audibility of the absolute phase were most likely professional radio engineers, among whom there are practically no people who accept the existence of sound of individual wires. However, these people heard the difference during the comparison tests and decided that this is how the absolute phase manifests itself. This opinion is widespread among audiophiles, but this does not naturally mean that it is true.

I don’t see a way to solve this problem, but my opinion is - the absolute phase can not be heard.


For the sake of clarity: I assume we are discussing polarity, not phase. And it can definitely be heard. It manifests itself as a strange hesitance in attack. As though a woodwind would suck in air rather than blowing it. Unfortunately there are numerous studies indicating that the majority of recordings are out of polarity. Using a phase inverter is a good way of training one‘s sensitivity to the phenomenon and it should be standard issue on music servers
