I've been having a lot of trouble recently with the sound of my system going off.

After much mucking about I finally traced it to oxidation of the cheap spades on my Van Damme Hifi speaker cable.

At 1st I went bare back but I found the sound would go off again after a few days. I didn't expect this as I thought oxidation of bare cable would take much longer.

Anyway, I finally bit the bullet and bought some red copper Gaofei spades from ebay, some silver plated crimp tubes and a crimping tool.

I put it all together and covered the open parts of the spade with heatshrink and voila, lovely sounds and so far it hasn't gone off!

I'm not sure why the banana plugs at the speaker end haven't also gone off but maybe they were better attached when I bought the cable.

Just thought I'd share my findings in case anyone else has experienced oxidation or just to stimulate some discussion
