Vibrapod Isolators under my speakers?


I'm just messing around and tweaking some. My KEF Reference Twos sit on about a 7" high tile ledge that also holds my other components. I have some Vibrapod Isolators that I was thinking about putting under the KEF's brass feet. Is this better (or overkill) than just having them sit on the brass feet alone? Also, they seem rock solid at loud levels. Should I skip adding any sand or shot to the plinths? The components have Vibrapod Cones underneath them BTW.

Thanks for any input.

Has anyone thought of actualy fastening speakers to the floor, the whole idea of feet, spikes and etc is to keep the speakers casing from moving at all, only the cones'n'domes should produce any sound, if you are fortunate enough to have a concrete floor, some suitable masonry expertise should render the speakers absolutely immobile. Wooden or chipboard floors are a different problem, each situation would require its own particular 'tweak'

I put Vibrapods under my Linn Keilidh speakers when I moved in to my new house. Wasn't thrilled with spikes on wood floors. It has been a few years, but When I did it I went back and forth between spikes on quarters (to save my floors) and the vibrapods and found the vibrapods gave a little crisper bass. MY Keilidhs have the stone plinths just for info.
