Do speaker cables need a burn in period?

... Those who ask for measurements get attacked for asking for such a ridiculous thing as measurements. Those who suggest blind tests get ridiculed for such a flawed thing as blind tests. ...

I don't see that happening here at all. 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.

i see the reason for a car’s brakes - to heat treat the rotors evenly and burnish an set the pads, but I have never seen any explanation for speaker cables.

>>>>We see that here a lot. They frequently say proudly, “I have found no evidence to support their claim.” 😛 Just because you see no reason for it doesn’t mean there isn’t one. There is no apparent reason why a super huge black hole 3 Million times the mass of our sun is in the middle of our galaxy, either. I thought all the world loves a mystery. Ah, sweet mystery of life!

In short, there is no way you can be right

That is sort of the problem with these threads, everyone wants to be "right", everyone believes they are "right", and everyone wants everyone else to acknowledge they are "right". Never gonna get there. Of course these threads would be a lot less fun if everyone simply stated their case objectively and moved on.

I think one of the reason is with real world objects such as car brakes, you can see it with your own eyes.  With electrons and molecular structure, it's hard for people to see or understand how things work at that scale therefore one has to have some back ground in electrical engineering.  
Imagine a molecule and a billiard ball.  The difference is the billiard ball is composed of many molecule, but the molecule moves and disturbed in just about the same way as a billiard ball.  But most people probably can't visualize a molecule because visually you cannot see a molecule therefore it seems somewhat mysterious.   The billiard ball and molecule are both governed by the same principle: F = ma. 
Once you could see how molecule, electrons and their behaviors are not that different from a billiard ball, then maybe you could understand the effect of break-in.
