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?

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...
Pbb,

Not a musician and sounds good to me, as well as many others who have heard my system. Why do you ask?
A Sound Anchor amp stand under my Cary 40M monoblocks transformed them----more dynamic, more detailed, and more coherent. This was compared to a solid wood stand that I had tweaked to get the best sound.

Dennis,

Have you looked into the VR Series of Platforms from Silemt Running Audio? They are much less costly and up to 85% as effective as the OHIO Class bases. I am one of the biggest Doubting Thomases around, so when I reviewed these things (both the Ohio Class and VR platforms) for Stereo Times a few years ago, I was shocked at the difference a PLATFORM made under my amps. Like PBB, I had those same thoughts and doubts. I don't have time to go into it here so I'll give you two sites (one is my review and the other is Marc Mickelson's curent review at Soundstage [where I am now]) Maybe these will help - maybe not as it is all opinion and preference in the end in any event.
