Home Depot Ext. Cord for Speaker Cable

The third wire could be combined with your Negative cable, it then has a thicker gauge to ground.. Will it make a huge impact on sound, probably not, but you can at least use the copper on hand.. It will not hurt it. I have actually opened many speakers up that use a thicker gauge wire to the negative terminals for a path of lesser resistance, the positive can stay thinner.. Again not saying it is necessary, but you can at least use the wire.

I tried the variation Undetow recommended, liked it better than the "original" two wire version, but not nearly as well as the separate ones I ended up with.

Thanks everyone for your responses. Can anyone speculate on the difference I would hear, if any, between the HD and my current Monster wire? Thanks,
Bill

Mac tube gear deserves better than HD DIY cable or Monster for that matter. That's like putting ketchup on a good steak. You would be better off spending $ on tube upgrades or better wire.

Steuspeed, have you heard them? When it costs less than 20 bucks to try them, why not? Paul Seydor in The Absolute Sound review found that they sounded every bit as good as the $400-500 cables he was testing at the time, and he was using a simple two-wire version.
