Nordost Speaker Cables

Has anyone ever tried 'shotgunning' 2 sets of Nordost speaker cables. After demoing the Heimdals and Freys I had to say I had to 'squint' to hear the difference - But I did hear a difference. I did end up buying the Freys. That got me thinking (I know I shouldn't do that) but has anyone tried running 2 pair of speaker cables to 1 set of speakers? Like 1 pair with spades and 1 pair with bananas. If so was the difference minor or major? Would it be like getting a pair of Vahallas or Tyrs? I know there are other differences like dual mono filament - more wires and a heavier gauge.

Thanks George
