I have a Bright Star Audio Sandbox with German Acoustic tonecones underneath it. I took the rubber feet of my amp off and I have the lip of the amp on the styrofoam strip that runs around the square interior of the sandbox. On top for the dampening I have the Bright Star Big Rock which pushes it flat on to the sandbox.
What's under your amp?
Interested in hearing the importance (or not) of isolation platforms for amps. Check my system, you'll see I've got my Cary's sitting on top of my cabinet, which is a custom piece made of solid cherry. Very solid, but I'm wondering if maybe the cabinet is introducing vibrations up into the amps, and maybe I could use some help from a platform?
