The Original Budget Tweak is Still Going Strong! 

A Stereophile Recommended Accessory for the Last 18 Years! Recommended by John Atkinson, Sam Tellig and Robert Harley! 

The AudioPrism CD Stoplight (the green pen) is the Original CD Tweak and has been around for the last two decades. No tweak can survive this long unless it's truly effective! The CD Stoplight is one of Music Direct's all-time best-selling budget tweaks. Just paint the edges of your CDs to greatly reduce disc read-error and reduce jitter while improving clarity and reducing glare. We have sold the CD Stoplight to well over 5000 customers in the last decade. This tweak really works and it's affordable and simple to use!

"This stuff works! The cost per disc of this tweak is almost zero … it offers a big bang for the buck and can be confidently recommended!"
-- John Atkinson, Stereophile

Highly Recommended!
