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...

Now let's see, where did I keep that receipt.....
i use furniture foam, about 4 inches thick under a cd player/transport and dac. the cd player is a vincent cd s6 and the dac is ess technology sabre 32 evaluation board.
L'Art du Son fluid has a dramatic effect on CD's. Richer, fuller sound, lest digital sounding.
