The molecular level explanation of "cable burn-in"

"....there are no measurement data or mathematical formulas to be found to back up this amazing scientific discovery...."

Therefore, at least according to the way I understand science, there was no scientific discovery, even of the mundane kind.

God bless credulous individuals: they keep capitalism humming along.

My speaker cables have achieved greater transparency and neutrality in their sound reproduction abilities due to the introduction of concentrated and directed external sound focused to aid in the cable's molecular strand orientation. You can achieve this at home with any system by shouting at your cables, that's right, shouting at your cables! It's best to perform this exercise with no music playing since you do not want any reproduced musical signal to interfere with the intended orientation you are trying to achieve. Very simply, stand over each run of cable and while leaning over, cup your hands and shout. It doesn't matter what you shout. It can be something like, "Get in line you stupid cable, YOU SOUND LIKE GARBAGE, you need to get your particles in line so you sound better." Shout, loudly, 3 to 4 times for the left channel and 3 to 4 times for the right channel. Preferably leave the door to your home or apartment open so you don't induce any acoustic feedback or echo which could unduly affect the molecular orientation you are trying to achieve. Now that you've completed this no-cost upgrade to your speaker cables, put on your favorite reference music, sit back and listen critically and don't tell me you can't hear an improvement in transparency and neutrality, presence, and overall inching closer to the absolute sound of real music reproduced in your home. If not, repeat the exercise described above until you can hear improvement. Trust me, be patient, it will come. 

The best joke and sarcastic sentence must be short...

Your post is not even humorous...

Welcome here though... You will perhaps learn ...

My sincere best ... 😊

In my 40+ years of audiophile listening, I do believe that break-in of speaker cables and interconnects is necessary and happens.  I don't prescribe to know the physics behind it however it's been a phenomenon I've experienced many times over with a variety of cables, inexpensive to expensive.  I recently purchased a set of Iconoclast speaker cables and interconnects.  I really appreciate the time Iconoclast (Galen Gareis) took to develop his white paper on speaker cable design.  I really like how the cables perform in my system.  While they don' specify a break in period, after about 100 hours of play they have smoothed out and sounded for lack of a better work more refined.  They have a few conductor choices of copper-types and one with silver plated copper.  They say each measures the same, but the types of conductor do sound different.
