Have you been looking to upgrade your system for peanuts yet want to hear the audiophile quality that so many crave? I have the perfect solution. Sit in a triangulated equidistance between your speakers, play a CD (or whatever) and cup your hands around the back of your lugs, making sure the fitting is tight and snug. Can you hear the improvements? Genius or what????? I claim the patent on “lug cones”….
