Talking of Speaker Cables....

Just a small, probably insignificant question for anyone who might know the reasoning for what I see. In one set of my speaker wires the positive cable is, or has, turned a darker shade than the others. I know it wasn't this way when I first had them and sound quality doesn't seem affected. I wouldn't have even noticed this until my wife wanted to paint the living room (got suckered into that one). Anyway, the negative side is still the same as the other cable(s).

Just wondering if anyone else had this happen and if it's a bad sign of anything.

    Your copper wire was either contaminated from the start at the factory or they've oxidized.

    There is a chance that when the wires were produced in the factory, the L and R sides came from different spools before they were joined together so the good got mixed with the bad..
    While in the living room, did you have one side tucked away in the corner or under the carpet and the other exposed to sunlight?

    That's what I"m thinking too. I had a pair start turning black after a couple months. I think that was because the store had it's spool right by the window and exposed to sunlight all day. But I think yours may be a manufacturing issue.

    I've had the wires for quite a few years now and I'm guessing this started about a year or so ago. They've never been in direct sunlight as the living room faces the north. Funny though, the wire that is darker than the others isn't the same shade throughout the whole length but seems to be progressing. It starts at the speaker, going back to the amp.

    Can I stop this by splicing the dark out or am I screwed? Also, is this going to screw up my equipment?

    Speaker wire is cheap, comparatively, to equipment (at least for me).

    Definitely can't stop the oxidation. It will only get worse.
    It won't hurt your equipment, but it won't perform at its best.
    Treat yourself to some new cables:D

    could be mold growing that feeds on the copper...

    The dark color of the wire is going to muddy the sound. Unless you like your music dark and lifeless, like the Virgin Prunes, you should exchange them for a lighter color.

    Take those cables and throw them out the front door, then buy some fresh new higher quality cables.

    I would love nothing more than to purchase new speaker cables BUT..., my current employment might very well be going over the other side of the bubble in the next couple of weeks. So..., right now guess it's a guessing game as far as that goes.

    One thing is for sure, I've never had speaker cables do this before, even the heapy cheapies haven't done it!
