Do speaker cables need a burn in period?

GK: nice try :-) But man do you get ’em going!

Next we should talk about whether the composition of baryons in wire metals, such as protons (two up and one down quark) vs. neutrons (two down and one up quark) are what's really 1) being burned in and 2) account for directionality.

Because it ain't fermions such as photons, my friend.

There are too many people with no electrical engineering background saying things that just makes your head spin.

It's complicated so don't simply things.  

Do this simple experiment.  If you don't understand the reason behind this experiment then maybe you should listen more than post. 
The low pass component in your speakers cross over is usually an inductor.  For example a typical inductor for a two way is about 1.2mH which has many meter of cable in length ... may be even 10 meters long or more.  This inductor is in series with your speaker woofer.  Of course the amp is connected to your speakers through a cable and this cable is then connected to the inductor of the speakers.  So the current travels from the amp to the speaker cable to the inductor and eventually to the speaker woofer.
Now if you use a 10 meter long speaker cables from your amp to drive your speaker you probably won't like the sound very much.  So why would 8ft of speaker cable make any different because the inductor already chews up 10 meter long or more?

How electrical current travel is complicated.  The length itself is just one variable.  It's not the only thing.  This is why power cable makes a difference.

A lot of people use water as an analogy and come up with all sort of wrong conclusion.  The difference between water and electric current is that before you turn on the faucet in your house, your house has no water.  On the other hands, electrons are everywhere even before you turn on the switch.  The electrons are already in your equipment.  This is just a simple example.  It's a lot more complicated than this.

One thing is for sure. If the 10 meter inductor copper wire were controlled for directionality the speaker would sound better, dammit. And it wouldn’t cost anything. Think about it. 😳
