To all who are stating that speaker wire is speaker wire, how many of you have actually listened to various wires? There are measurable parameters such as capacitance, resistance, and inductance that do differ from cable to cable that can alter sound. Also, dielectric materials, wire purity, and many other factors could be involved. When you look at a painting you form an opinion based on how your brain interprets it. Isn't sound just as complex? Is it possible that some people interpret subtle changes in sound as appreciable differeces while others don't really notice the difference? Just relax your balloon knots and maybe you will hear with an open mind.
