I have a pair of biwire jumpers made from original Monster Cables 12 ga wire. They have a clear coat and you can see that the copper has turned a nice barf green (it did this in less than 5 yrs). These were terminated imediately and had soldered ends on them. If they hadn't been clear coated, I would have never known.
On the other hand, I have a 20+ yr old set of Straightwire TMC speaker cable that has a clear coat and you can see the copper is still as shiny as a new penny.
So, life expectancy? Who knows.
Makes me wonder about "black" stock power cables. What's going on inside them? Could this be why some people hear such a difference when they try an aftermarket one? Hmmmmm.
