Yeah, I know he's correct. I was surprised that he tried it and I was wondering how exactly he terminated it. I wasn't kidding. A coat hanger will sound as good as any cable provided the amplifiers in the circuit are designed correctly. If not, they will fall victim to RF interference.

Coat hanger wire can also be used to make low cost but effective electromagnets. The lamination on coat hanger wire reduces eddy currents.

Thanks for the priceless links by the way .
