I have looked at the electra tube website and would like to try them.
Don't laugh, I have monster cable Z1 speaker cables. I know they aren't really that good. I got them super cheap when I worked for audio king. $30 for a 10ft pair. Anyway, I know there are different windings and whatnot, so I don't know if it would be worth trying to use electra tubes for my cable. They are fitted with banana plugs right now, so I would assume, using the electra tubes on the speaker end would still be a little better than regular speaker cups. Right?
I can see both sides of this debate about changing a product. Frankly, some people who buy second hand aren't always informed and want to know everything is on the up and up.
