Where is Clark Johnsen when you need him? He reviewed a bunch of CD treatments including Jena Labs, Nanotech 8500, Ultrabit, Liquid Res, Optirx, CD Clarity, Auric Illuminator and others in his article Lotions Eleven in Positive Feedback Online but that was quite a few year ago. What we need now is some exceptionally patient individual to step up to the plate and compare all the latest and greatest CD treatments. One wonders if there's any advantage to using more than one treatment, say Nanotech 8500 and Essence of Music.
