My speaker cables are more than 10 years old now.
My speaker cables are more than 10 years old now. I wonder if I need to replace them. What if they are corroded internally? I would need to cut them open to inspect. Sound-wise it is difficult to tell since I listen to my system everyday.
If the cables are well-made, they should not be corroded internally. Normally, the corrosion occurs in exposed areas such as where the bare wires are soldered to the plugs. You can unscrew the speaker plugs and see if there is any corrosion in the vicinity of the area where the solder is.
