I did this with Linn Majik 140 speakers and Lipinski L707,s. I sold the Linns because there was enough difference in sound. I decided to keep the Nordost, and sold the Kimber, but again, not much difference between the Kimber single wire and the Nordost Bi-wire. I got the Nordost Blue Heaven for 250.00 so I guess it was an ok deal, since I made a few bucks on the Kimber. One thing I do know. Don't spend much more than that on wires. They won't make that big a difference. I'd replace a component first. Thanks to all.
