A silly product, based on real science. There is indeed a slight piezoelectric effect in some SS parts, which if dampened would improve sound. This crap won't do it. More important is the fact that PCB gear has an insidious quality--- the PCB and voltage-carrying components work together like a very small capacitor, with the glass epoxy acting as the dialectric. This is very much present in tubes, with the top mica and tube elements acting as a mica capacitor. How the tube handles this is one of the many factors that give 30 different brands EL34 30 different sonic signatures. Back to the crap in the link-- this is classic inductive reasoning where a partial truth is extrapolated to support pure horseshit... much like saying "Ford did cryogenic work during WWII, Nascar teams cryo certain metal components" Very true. To say that "because (very narrow application) benefits are derived from cryogenic metal treatment, it must be great for vacuum tubes" is both inductive reasoning, and pure horseshit. If you research the processes used in the Nascar and Ford military research, you will see that it is part of an annealing process applied to a piece that has several steps to go before completetion. Dunking an Isky cam (or a 12AX7)in liquid nitrogen will just make it cold.
