To the person(s) asking about why does it matter if there are hundreds of ft of wire are running in the wall. I’ll borrow the words of a man much wiser than I am to answer.
Misconception #3: There is up to a hundred feet of wire in the walls, so the last 6 feet of power cord can’t possibly make any difference.
Answer: “The power cord is not the last 6 feet, it is the first 6 feet from the perspective of the component. As stated in #1 the local current and electromagnetic effects directly affect the sonic performance of the component.”
It usually takes a wise man to point out the obvious. The power cord is indeed the first 6 feet. People that don’t understand why this is, maybe grab the closest person next to you to ask for an explanation.
