The molecular level explanation of "cable burn-in"

According to one cable seller

"The insulation (or dielectric) will absorb energy from the conductor when a current is flowing (i.e. when music is playing). This energy-absorption causes the dielectric's molecules to re-arrange themselves from a random order into a uniform order. When the molecules have been rearranged, the dielectric will absorb less energy & consequently cause less distortion."

So it’s the plastic polymer (as dielectric insulation) to undergo some sort of molecular rearrangements to minimize the distortion. Probably one of the greatest scientific discoveries ever!

“Many premium AC cords constrict or compress the audio transient as their characteristic impedance restricts the transient current.”

We all know impedance restricts current but how possibly “many” premium AC cords constrict/compress the audio transient (when not carrying audio signal)? Then again is it achieved by this molecular rearrangements of the cable insulation?

Unfortunately there are no measurement data or mathematical formulas to be found to back up this amazing scientific discovery. Simply “it happens”. So I came up with a formula for them.

∆E = P - SoT

∆E: energy absorbed by dielectric

P: energy (power) drawn from wall outlet

So : Smake Oile

T: Dielectric Transition Temperature


I’m retired as many on this site, perhaps repetition Is a byproduct of forgetfulness. Over and over with 0 resolve, he said she said I say….who cares ! Enjoy what you have, snake oil or not and let’s move on.


If you look a Belden wire catalog they make all types of wire and fiber optics. They rate the insulator in capacitance per foot and the longer the cable the higher the capacitance becomes. The indicatance is from the wire and is rated in frequency as reactance Xc. You can check Belden silver plated wire and teflon insulator and compare it to a PVC or insulator and find that it's significantly lower.

Facts are out there
