i sell a conditioned unidirectional wire for 15$ us a foot
fully burned in with your choice of connectors-8 colors available-(i start with home depot 12 gauge wire then perform some voodoo with my secret electronic conditioner- age for 6-8 months- find a sucker-sell them)
i can put you on my waiting list if you want-that only cost 50$ for application fee(i check were my babies go)lol
if you want to bi-wire use the power cord thats 12 gauge by 4 wires works nice -only 70 cents a foot-and you only have one wire on the floor for each speaker
i tried the onix brand it was a joke(sp100)
