Post Subject: Err... The "house" cord is better...Posted by Paul S on: 6/28/2008
Sneaking up on the AC cord for the K&K, I recently added a close approximation of the power cords I made for the ML2s. These cords use 3X 12 ga. copper magnet wires tightly sleeved with poly tubing and braided, with Onyx pure copper plugs. I connected all three wires to the 3-prong wall plug, but I left the ground wire disconnected at the component/IEC end. This way, according to my shaky reasoning, the mains ground wire "draws off" stray EMI/RFI better than it does when this crap is allowed to "ride" the ground wire into the chassis/circuit and then needs to be drawn off by the dedicated chassis ground.
Who knows if I am on the right track in terms of electronics/physics? All I can say is, it works better this way in terms of sonics, including less noise/more music. Residual hum was barely audible at "24" with the ground lifted at the wall. The number is "28" with the ground wire cut at the IEC end. Is it odd that I have been listening as loud as 24 for the first time, since I installed the first (ground-cut-at-wall) power cord? I can't even imagine listening at 28...
