I have been of the mind set that due to the wires coming a long way to get to my equipment, the last few feet of the power cord can't make any difference. I have now tried different power cords and was surprised!! Now I wonder as I finish an area of my basement for my audio equipment if the wires in the wall generate a magnetic field that can interfere with the equipment. Which has more advantage for my money: the plug directly behind the equipment with a short (higher quality for the same money)power cord or off set the plug to one side away from the components with a longer (lesser quality for the same money) power cord?? I guess I should also say that the offset plug would put the plug closer to my Maggies tweeters which are less than three feet from the wall. Electrical Engineering or Audiophile question??
