My take on the (no) special cord needed, is more like the amp or device sounds great with a stock wire. However it can sound a little better with a better cord. As for my take on 'how' the last few feet of wire can (miraculously) 'fix' miles of wire errors... The power is a sinewave. Which can be damaged by the endless breaks and fractures in the crystal structure in the common poor quality (compared to high end copper) copper conductor. In those last few feet the wire is cleaner copper, and better structure in the metal. During the transition of the power through that area, it DOES become a more coherent stable waveform. smoothing itself out. Tightening the waveform itself. From my various power conditioners, they seem to focus the wave, vs the ragged base line power from the wall.Cords seem to do the same thing......
I have no science to prove this, but it is what I imagine. could be the reason the cords can work.But I also find longer (less than top dollar) powercords do better when they are longer. And this reinforces my suspicion that the reason I offer is the correct notion.(I do not know about the best powercords and length, since I never used any)
