Weights on top of equipment to dampen vibration


I'm looking into trying some of these. Are there weights specifically made to be placed on top of audio equipments, other than Mapleshade and Finite Elemente?

Musicfile, look at it as an adventure. Whatever you try experiment with many locations. This is true also for feet under the components.

My experience with the VPI bricks was they squashed the sound. I do use either heavy wood or  thick marble. YMMV

                                          SO MANY variables!
