Do Cables Wear Out?

Im not worried about my cables coming apart, nor do I subcribe to sales pitches trying so sell you a lot in the desert. I merely felt this a worthy topic of discussion. And to boot Van den hul uses carbon I believe for this very reason.
Where I was using the word particle I meant and should have been usinig the word "Crystal" as my friend corrected me. Im also saying I have not heard this degradation myself, yet. Here is an excerpt by a respectable leader in the industry. For further reading, http://www.vandenhul.nl/artpap/hybrid.htm
PS the metal he refers to below is copper and silver as further reading reveals.

First a short discussion on metal conductors and their vulnerabilities:
Due to the current cable manufacturing processes based on economics and aging, all metal conductors are sensitive to growing chemical boundaries at the edges of their internal crystals.
These chemical boundaries form non-linear conductive barriers for the electrical signal to be transferred.
The main reason for the origination of these chemical boundaries is the rough industrial handling of the basic material during the manufacturing of the single leads by pulling the metal through many dies and the unprotected storage in between. Especially the bare storage of the drawn wires on reels in the open air creates another problem: chemical interaction with airborne reactive components and their subsequent deeper propagation into the metal during the next processing steps.
As you can imagine, the result is that the final conductor still looks like a conductor, but on microscale does not exactly behave like one anymore.

As a side note, apparantely Audience think the bending and handling of cables will also affect performance. Below is an extract from its website.

"But did you know the act of bending them irrevocably damages the conductors? This bending stresses the metal and causes fractures along the circumference of the bend.....Damage to conductors is why some cords need "break-in" every time the are moved or bent. This is because current passing through the conductor partially repairs damage by micro-welding some of the damaged area. This helps but it will never restore the cable to its original state or it's original performance potential"

V.D.Hul is right. Another issue is that the cables are often emotionally stunted from the rough words they hear from factory workmen while still in their formative stages. The best manufacturers buy cable from a secret plant in Sweden, all workers are virgins, men handle the bass conductors and wimen take care of the rest, the nature of the shop requires that the virgins are ugly (or have another job lined up) but happily this has been found to make the cables sound more real. Birds sing constantly during the manufacturing process, temperature is held at a constant 76 degrees f with 42% relative humidity, and the shop is always lit to resemble the first hour of morning on a great new day.

Jeff_jones, you are forgetting that the aforementioned virgins are kept emotionally stable by sipping constantly from mugs of fresh milk expressed from dairy cows who have been kept in a state of constant bliss by playing to them Mozart's Eine Kleine Nachtmuzik 24-7.

I do have to admit thee are times when "something is not right"---perhaps a buzz in one speaker, a fallen bi-amped connection to one of my speakers, or maybe my Satellite box re-setting itself to factory settings and outputting Dolby instead of PCM so my DAC can't decode it that it is possible my whole system's lifespan is somewhat threatened. Especially shortly after the second glass of wine which about when "something goes wrong".
