Maluvia spoke in tongues: How, then, does the sound know which direction to go? You're not worried about rectification or picking up AM radio, are you? If I had cables with the arrows, how much would it cost to upgrade to cables without the arrows? Is there a kit? How would you characterise the difference between the sound of the older and newer cables? If I were to build a suspension bridge out of such cables, provided they were aligned correctly, would anyone be interested in purchasing one? (I bet it would sound great!) Just asking, of course.
