OP asked for speaker cable, let's keep with that.

This cable comes close to my Decware speaker cable which is quite good. Remember, you need 4 runs since it's sold as a single strand.
24' = $240 Too rich? www.signalcable.com
That is also very good wire for less money, but is not quite as good as the Duelund. I have both, so have compared them.
