Vibration control devices for EMM CDSA.

Heavy brass footers like the "fat bastards" that were made by Edensound an Agoner. I don't know if he still makes them. If you use the heavy footers on a platform that itself rests on viscoelastic foam or has dynamat affixed to it the dampening improves.
In addition you can use any heavy solid weight on top with similar effect. Mapleshade and Walker Audio makes Valid points and various brass pucks and such for the purpose.
I find that dampening actually has a very favorable effect on my gear. I have heard overdamped speakers however so I do know it can kill the sound if overdone.
With the various solutions available and the DIY aspect of it you can apply as much or as little as you need.

Time to try 'moon gel'. Available in most musical instrument stores. They are used by drummers to deaden transmission. At six dollar for four pads, you can't go wrong, especially since they are returnable.

That moon gel pad looks like a softer version of the Sorbothane footers by Herbies. The Older Sorbothane footers can support a piece of equipment. These moon gels can only be applied to the surface. As you say they look like a useful accessory especially for a real world price but I think you will need additional materials.

I have a silk cushion under mine. It works nicely. I will be getting SR MiGs soon that will replace the cushion and I'll let you know how they work out. I am also using 4 Totem beaks on top -- one near each corner -- with very good results.

Thanks everyone and Sabai once again.
