Don't forget to freeze all your CD's ( twice is for optimum improvement)
Also outer edge and around the central hole paint with green pen.
If the above is performed ,a marked improvement in audio clarity will
immediately be heard.

 

Freeze the cd's?I live in Maine,and the cd's in my car are always frozen,so I wouldn't notice I guess.What's with the green pen?Does it keep the light inside or something?
I'm curious.
