We discovered that during playback, that a significant quantity of stray laser light bounces around inside a CD. This stray light eventually finds its way back to the pick-up assembly, creating jitter. CD Stoplight was developed to passively reduce the the effects of stray light that ultimately causes jittar. By absorbing the stray light at the transport passively, rather than attempting to reduce it's effects downstream electronically, jitter is reduced at the source-keeping it out of the playback chain.
Packaged with a special applicator, CD Stoplight is easy to apply. It is non-toxic, environmentally friendly and will not flake or peel. Compact Discs treated with CD Stoplight sound more neutral, less edgy and significantly more open.
