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?

Can anyone here explain what the mechanism is that would excite something inside a ss amp that vibrates because it is not "isolated"?

Is it not besides the point to use a platform when air-borne vibrations will strike the amp nonetheless and, assuming there is a mechanism that somehow affects the sound coming out of it, cause problems?

Why not build a concrete shelter in the backyard and run longer cables?

Pretty sad when you can't see that mega buck power amp looming in your room though.
Underneath I have Stillpoints with risers sitting on top of a 2 inch thick maple amp stand. On top a VPI brick for right now, I've used HRS dampening plates ion the past.
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.
So, SRA silent running audio makes some cool floating amp stands for my cary, but they are over $3000 for the pair!! that's almost as much as they cost used! dang...
