So R_f I think you may have hit upon why Audio Research preamps sound so good (to many ears), where most companies put the left channel in/outs on the top and the right on the bottom, ARC reverses this and puts the right on the top. I'm sure this and your "positive ions prefer red" theory account many of the variations heard in today's equipment! ;)
What colors match for interconnects?
When I'm matching up interconnects with components, there is a strange little conundrum I sometimes encounter. The three colors; white, black & red. Or sometimes no colors, just left or right. Is there some simple rule of thumb for always selecting the right color or side? For example, is white, or left, always hot(pos)? What if your RCA posts are red & white, but your cables red & black?
