Home Cable Asylum

Interconnects, speaker wire, power cords. Ask the Cable Guys.

There are various theories

about burning in cables. Some feel that the high current is answer (Hagerman) and that the high current molecularly reorients the cable molecules to a certain degree. His device has frequency steps, as do several other such devices (the Duo Tech comes to mind).

Most take a demagnetization approach. Those cartridge demagnetizers usually employ a tone burst with a controlled decay. The Gryphon people marketed such a device which you could plug into any of your preamp inputs and it basically sent a 1KHz tone burst with a 45 second decay, if memory serves me right. It was called the Exorcist, IIRC.

The most sophisticated one I've seen has been the Purist Audio Break In disc. Perhaps because every time you would move their fluid jacketed cables the sound would change, they came out with a disc of what they claim are 125 test tones to demagnetize the most common materials found in the signal path ) aluminum, copper, copper clad aluminum, silver, silver plated copper,iron wire, etc., for example). Listening to it is like having the robots from star Wars going mad i your listening room. There are beeps, tone bursts, tone sweeps, and all sorts of weird effects going on.

I've experimented with running a tape degausser down the length of my speaker cables, and there is definitely sonic improvement, but that improvement fades rather quickly, within a few minutes. The kind of audible improvement is consonant with using the Purist Audio Disc, but their method lasts considerably longer. They recommend once a month but I find that with heavy listening two to three weeks is more appropriate.

George Cardas used to recommend playing a nature recording with a lot of running water. He claimed that water sounds were a good source of full frequency white noise.

YMMV, of course
