Do speaker cables need a burn in period?

Addendum for Andy2. I respectfully suggest the billiard anology is incomplete for electron flow. Quantum principals come into play, the role of "electron drift" vs signal transmission makes for fascinating reading. For me, the bottom line is that for signal in vs signal out, in the wires we are discussing, the physics is well established and not altered by a few hundred hours of music olaying time.

+1. @cleeds  You said " What I do think is odd is that those who clamor for others to pursue measurements or blind testing seem so reluctant to undertake the work themselves."  EXACTLY!  If you are appealing to the importance of measurements then supply the data to prove your assertion.

One more thing... Do the scientists and electrical engineers here truly believe that all happenings have measurements derived from scientific experiments that explain those happenings?

Metaphysics baby....metaphysics. 🧐

No, at least I, me, this EE, do not believe we have science derived explanations for many things in the universe, and especially in our heads. But for audio frequency signal transmission over several meters of cable, yes, I do.
Don't forget that the military and big industry has had huge interest and investment in this exact topic for over 100 years.  So they have looked hard at both hypothesis and practicality.

So, help me understand. You think that anyone who disagrees with you is creating a pissing contest? Is that that the EE part of your brain talking or the pharma part?

@ganainm   Can you please share the science derived explanation regarding the fact that cables do not break-in?
