Anyone use CD tweaks


I was wondering about the effectiveness of products hyped to improved sound quality - i.e. products like Maple Shade's "Mikro Smooth" for polishing CDs and their "Optrix" surfactant product. You want to believe these claims, but sometimes they sound too good to be true. Anyone with any experience with these or similar CD enhancers??

Thanks in advance...

Another vote for Shine-Ola. I use it and definitely hear improvements. The sound if often more open, transparent and detailed.

On some CD's the improvements are significant. On other CD's it is subtle.

I think that the improvements are more obvious as your system becomes more revealing.
