Red and Blue Intelligent Chips. Sound familiar?
"The original GSIC (still around and upgraded, by the way) is used on CDs and its effects are permanent. The new ones are placed on top of transformers and power cords and their effects are completely reversible. They come in two versions: the light Blue is for use on amps; the orangey-Red is for front-end gear. I can merely hope the fracas caused by the original GSIC is not to be repeated."
