I was browsing around and came across a video claiming that putting a copper jacket over certain parts of cables eliminates magnetic leaks. I am a believer in audio tweaks but have never heard of this one. Anyone here ever do this, and if so, did it make a difference? Ever tried that little device he is using on your own system? Here is a link to the video where I saw it. Goto about 1:28 in the video and this is where they guy starts showing you what I am talking about. You have to watch the video to see what I mean exactly.
