Same here with Mapleshade. I have a 500 pound, 4 shelf, Samson v3 solid maple rack, and Micropoint brass footers under all electronics, except the 150 pound amps, and it seems to work quite well. I can pound the music and vibrations on the gear and rack are nill. Of course, as always, there is probably other things that give the same effect, or maybe a tad better.
