Anyone try different footers for DeVORE Super Nine speakers?

The other thing I' am looking at are the Gingko Audio Speaker Arches. They would raise the height of the speakers a bit.

Nice speakers.  Many people have gotten significant improvements with Townshend Seismic isolation products.  Not cheap, but I believe they offer a return option and very worth considering.  Read the reviews that are virtually all raves, which is rare for tweak products like these IME.  Just another option, and best of luck.

+1 for Townshend Seismic Isolator platforms and bars. Helped with better definition and unmuddied the bass. I am on a suspended wood floor, so vibration was a problem. Not any more!

@elliottbnewcombjr - Thanks, I may give that a try. 

@ Soix - Thanks. I have looked at the Townshend stands and yes they are pricey! My funds at the moment are a bit constrained, so I have been looking at less costly options. When finances improve, I may pursue the Townshends.
