I have never auditioned the anti-wires.
I have an Exemplar 2900 connected to a Bat integrated via a Yamamura Millenium 6000 interconnect. Both are powered through Foundation Research LC2 conditioner/power cords. My speakers are Opera Quintas.
Today I went to the Home Depot and purchased some 14 Ga. solid copper wire, red ones for + and green ones for -, and used these for speaker wires.
They're about 4 feet long, bare wire at the amp, bare wire going through both
the speaker binding post. I separated the green from the red wires by placing
wine bottle corks between them at about every foot, and tie wrapped the wires to the corks, two tie wraps per cork. I then ensured that the cables were bent well away from other wires, components, walls and floor.
I then started listening and became immediately aware that these solid core copper cables that cost me less than $6.00, right of the roll, totally blew away the $2,500.00 speaker cables that they replaced.
Try it, you only have six dollars to lose!
