5 or six years ago, things like the Gryphon Exorcist, and such, they claimed to demagnetize the circuit. The Exorcist just emitted a 1kHZ toneburst with a 30 to 45 second decay. and they claimed this demagnetized the wire the signal was going through.
People like Purist market a disc with what they claim are 100+ programs to demagnetize the most commonly found items in your circuit path. There is a change with the use of such devices, but how does one measure and test their hypothesis?
I took a simple hand held degausser, a Geneva 2800 Gauss machine used for tape erasing and simply ran it down the length of my interconnects and speaker wire. The effect was identical to using such devices, except the effect did not last as long as the Purist Audio treatment (a 74 minute CD). I could hear the sound changing within a 5 minute span.
I am hypothesising here, but the current flow seems to be magnetizing the insulation and the boundary material next to the actual conductor, if not the conductor itself. What is surprising is that such small changes in the magnetic properties can be heard (at least by some).
One speaker designer I've spoken to thinks that part of driver break in is due to the annealing of the voice coils and the inductors, saying that that would explain why you have to push a driver in order to have it break in, meaning the wiring has to heat up some.
I'm not saying this is the cause, but it is food for thought.
