Vibration control question....

I guess some serious answers are out of the question ???
(sorry......I'm having a bad day)

OK, Muskrat, good point. I would try placing the cdp directly on the granite; I wouldn't decouple the granite from its support with vibras. I'd try the vibras under the cdp and compare to cdp direct (above).
Given its mass, the granite's resonance frequency should be quite low -- be aware however that it can store energy so, you'd probably want to decouple yr cdp fm the granite.
You must try various combinations (granite is heavy, I know).

Sorry Muskrat, Stanhifi only allows serious answers from people other than me.

Hey.....no problem. I set it up last night using cones under the cdp into the granite. Sounds good, but its a new house, new room so I still have to tweek speaker placement, etc.
Any other smarta$$ remarks? ;-)

By the way, I did try placing jello shots under my cdp first. Sounded a little muddy.

That's odd, when I tried the Jello shots under the CDP everything was real thick and overly sweet, kinda like tubes!
