Crack detection frequencies for eddy current skin effect tend to be in

I'm surprised no one's said this yet, but 1000 hours = 41 days. I bet
the cable you buy every 4 weeks has sat on the shelf longer than
that...
Also if you use the $100/ft stuff, that's a ridiculously huge ongoing

Based on my own observations, I think there is a life span to these
products, but it does not have anything to do with how many hours a
signal has passed through them, but instead, relates to how long
they've been just sitting there -- whether in use, or not in use.

In fifteen years the electrolytic power supply capacitors will get

I guess you could argue the same for all components, not just cables.
Even more so for those with moving parts:- speakers, CD transports.

Well it is certainly true that electrolytic capacitors need to form
when new...and then after a while (years) they start to die...just like
rechargeable batteries...
Not sure this applies to wires though - never seen one die except from
corrosion caused by exposure to moisture.

Audiophile cables are usually marked with arrows to indicate
directionality. According to the laws of physics, this means that all
the electrons are flowing in one direction only. Therefore, sooner or
later, the cables will run out of electrons and you'll need new ones.
