Not snake oil.
There are three materials people use: woods, stones and synthetics. What I have learned is that I like wood - mostly myrtle but lets not overlook ebony and maple. I find that metal cones, blocks etc that sound gawd awful when placed on stone (so component, device, base) sound just dandy when placed on wood platforms.
The most cost effective tweak I use are a set of three myrtle wood blocks between an amp and my rack shelf which is basically some kind of stone.
Stone in my (limited) experience is a fine damper - great for mass loading from the top.
Synthetics are all over the place - there are so many kinds. Generally whether they be Polys, Vibrapods, or Isonodes they work to either stone or wood though IMHO they sound better touching wood.
YMMV
