Do speaker cables need a burn in period?

Twas not I who dropped his name.

So here I am in my recliner reading the newspaper after supper listening to classical radio. What the heck, I will check my email. I come across an Audiogon discussion recap and link to this thread.As I read a few posts  I get hooked, not because I have a strong opinion on the subject, but because the banter is at times informative and even more times evokes a good laugh.
I start to imagine that all who have posted and others like myself who just read and are entertained went to the same high school and were in the same graduating class. During high school and ever since we have been fervent audiophiles.  So here we are years later (45 for me) at our class reunion and a discussion of cables arises and spreads throughout the room. Lively, sometimes heated banter, along with rolling eyes, and gut aching laughter fills the place. 
It is probably good that this is only imaginary. Otherwise we may very well be a room full of bachelors.

"The reason cables are directional is the same reason......why power cords are directional."

The Mystery Of My Underperforming Refrigerator has finally been solved.

After a near death experience, I've thought about "directionality" and I think I may have to agree with geoffkait.  Yes, the cable is directional.  For example if you send a pulse from the source to the load, the pulse
travels from the sender to the load, not the other way around, which means it's asymmetric.  The AC current may be symmetric (that is it travel forward and backward just the same) but the current in this case is just one variable.  There are other variables that confirm there exists directionality. 
geoffkait will get the credit for coming up with the concept but I don't think he did a good job of explaining.  

As for those who insist on data, it's like asking to show the data for 2+2=4.  You need some background in electrical engineering.  Human concepts cannot be described in data.
