Removing spikes... Now my speakers sing

prof, yess good trick also

With all the possible combinations of speaker cabinet/flooring interactions possible. there is no one size fits all.Plus the likes of the listener. More bloom? vs tighter sound?Glad the op found something better. but IMO this discussion is not going anyplace.. except to say different stuff works for different situations.

Thanks again audiosens,

I’m going to try my 70 duro 2.5" diameter x .25" thick sorbothane discs too and see how it matches up with the Vibrapods. I agree with elizabeth too. There are so many variables it's best we try a bunch of stuff. Having some good experiences/reports here to build  on helps though.

asahitoro,  After so many years in listening to music, why not helping people with what we have discovered

different stuff works for different situations

Bingo!  That's what I was going to say but probably not with so few words.   Well done!
