Do speaker cables need a burn in period?

OMG, I can’t believe what I’m reading here. Speaker cable burn in? Are you kidding me? In this universe, what magical, non-scientific process are these speaker cables going through that’s going to change their physical characteristics? Basic physics people - there is nothing you can do to speaker wire by hooking it up from your amp to a speaker that will ever cause it to change itself. You can get your cables cryogenically frozen, add batteries to them, twist in a few "feedback loops" and it won’t change the wire or the manner in which it carries a signal in any way.
Yes, speakers go through break-in periods and electronic components do go through what one might term a "burn-in" but wire is wire. Some good 10ga stranded copper wire is all you need to effectively get the signal from your amp to your speakers. If you actually saw the wiring used inside your speaker to go from the terminals to the crossover and the various drivers, you’d probably faint. You can spend all you want to get that signal to your speakers but on the other side of that terminal you just connected to is much lower quality wire heading to the crossover - industry standard stuff. Don’t get sold on all this hype and snake oil that’s out there.

Burn in is experienced by many people. Enough to lend an argument that it could very well be viable. We have barely scratched the surface of physics. Just the basics. 

What?? There is tons of empirical scientific data on this topic, all over the world, over many, many years. It's long settled - basic - physics. 
Do certain audiophiles have some innate pseudo-scientific knowledge that only their finely honed hearing can determine?
Signal purity, strength, degradation is easily measured and demonstrable. These are well established, scientific FACTS.

We're not talking about the nature of the universe or time travel.

The industry absolutely loves the idea that some people are sold on the idea that they need to spend $200 a foot to get a better quality signal to their speakers. The finest, most expensive speakers in the world still contain simple 14 or 16 gauge internal wiring. Do you really believe that companies who manufacture $30,000, $50,000, $100,000 speakers have just been missing the opportunity to improve the sound of their product by simply improving the quality of the few feet of wiring inside their own products?

A forum like this should be a place to provide the community with helpful and correct information so people can spend their hard earned money in places that will truly enhance their listening experience and feed their thirsty ears. -not support an industry that has gotten fat, dumb, happy and very rich because they can sell a phony bill of goods to a certain percentage of the population. We should be putting an end to this nonsense and not perpetuating these myths.

Burn in is experienced by many people.

The placebo effect or expectancy effect is also experienced by many people.
