AudioPrism Lives!
I was delighted to discover that AudioPrism, originators of the infamous green pen (aka the AudioPrism CD Stoplight), is still in business. For newbies who do not know about the green pen, Collett and those who reviewed it shook skeptics to the core when they declared that painting the edge of CDs with the green pen lowered digital edge and improved data retrieval. The backlash was tremendous. Then Krell began bathing its CD tray in green light, some people found that green-tinted CD-Rs and then black discs sounded better, CD mats with green undersides made a demonstrable improvement in sound, and the skepticism was transferred to the next tweak on the horizon.
