Having tried a few of these treatments it is safe to say they are definitely for real.
I also use the Marigo Lab 3-D Signature CD mat routinely, although a cheaper way is to use Herbie's Grungebuster CD mat(s), to give you confidence in the ability of a tweak to instantly upgrade the listening experience.
Newer versions of liquid CD treatments are released even before one can use up container contents of an earlier version. One of the classic liquids in this category is the new and improved Auric Illuminator, and there is no question that it enhances the CD experience. You can initially try one "well reviewed" product, but don't expect unanimity from our diverse Audiogon membership on which is the only one to try first.
