Do speaker cables need a burn in period?

WHY are you all still working on this one?  I already posted the final answer:

I have PERSONALLY spoken to the electrons, and they stated unequivocally that they NEED BURN IN.  It makes it MUCH easier to travel down a wire that is already "slick" from the previous electrons that leave behind a smoother surface.  

Case closed.  (Interview the electrons YOURSELF if you doubt this--don't take my word for it.)

If a dealer had demonstrated or/and sold a cable, for some US $3,000.- plus, and unfortunately it is not delivering the promised superiority: What could that dealer or sales person say?
"It will open up and sound better after a burn in".

Only three posts in and you are way too clear-sighted and logical. Stick around, things become murkier over time. 

Yes, wait until you get Kat scratch fever. 🙀

I got you in my sights, flyboy.
