Do Cables Wear Out?

Does anyone know if capsaicin extract treatment can restore original conductivity in tarnished silver cables? Or in other words, will capsaicin bind to Silver sulphide and dissolve it?

Pabelson - just because you can't see gravity does not mean that there IS no gravity. I can say with a degree of certainty that most copper based cables that do not have coatings on the copper to prevent oxidation WILL suffer sonic degradation over time that is audible. Try this for yourself - run some lamp cord to a pair of outdoor speakers - strip the ends and connect the speakers. Enjoy the speakers all summer long. In the fall, do some critical listening to the speakers, then cut off the last 3" of wire , strip the insulation back and listen to the same material again. You will be amazed at the difference. Obviously, there will be more difference in areas of high humidity vs low humidity, so if you live in the desert, Pabelson, I understand - YOUR experiment might take longer to produce audible results for you.

Huh, now we can use outdoor speakers to do testing of the audibility of corrosion in copper wires, when a much more accurate visual test is available to detect corrosion. Maybe the difference has more to do with the fact that you have cut off a small piece of copper and then the connection is better and you could have abtained the same result by cutting off the cable when new and not submitted to so-called corrosion.
Salut, Bob P.

Naw, they sound better because after cutting the ends off the cables are shorter and have lower inductance, capacitance and resistance (sorry, couldn't resist).

Thank you, Zaikesman for that information. Im afraid in the begining I may not have stated my question clearly for some of you. My intention was simply to engage discussion on cables wearing out by any means. I believe the discussions to be quite edifying thus far and am pleased to see such intrest in this subject. Thanks, spl.
