"Much of the science behind power cords, interconnects and speaker cables has been explained. It takes a good background in Electrical Engineering to understand it."
You can't lump in power cords with ic's and speaker cables. Electrical engineers (like me for what it is worth) will tell you that one is connected to a device designed to accurately amplify or transmit a signal and the other is connected to a filter network designed to gobble up hash on the incoming power line. It is an apples an oranges thing.
In all honesty, if someone discovered a way to improve sensitivity of equipment by changing power cords it would be a significant technical advance and very newsworthy event. There would be great benefit and wide ranging application in medical, industrial and military equipment for example. It would be a nobel prize worthy achievement.
