"The is cheap copper full of impurities.. cheap insulation tooo."
The same cheap wire that is used from your wall outlet to your electrical panel box, that many have their very expensive audio A/C cables connected to.

I say try it, you never know. I tried this a while back (12/2, not 12/3 though) and didn't make much difference with my Klipschorns that I had then. Some speakers are more cable sensitive than others.
