Huge difference in sound : Spikes vs. Vibrapods


I have a pair of Martin Logan prodigy speakers which after reading a few discussions about coupling and decoupling, I put of Vibrapods. So I have decoupled the speakers from my tile floor.
Several questions now:
With this setup I das this tingling feeling in my stomach once in a while, which you get from a powerful bass, when the sound really drops low, like with a baritone singer. Should you be able to *bodily* feel the bass once in while or is this what is called a boomy bass?
When I put my speakers on spikes, I immediately had the impression that the speakers could not go as deep as they used to go before.
This gut feeling was completely gone. (I do not experience this all the time of course, only at certain, very low passages with a double bass e.g.) and I had the idea that the base is lacking almost a halve octave. Is somehow has lost its punch a bit
So when you read my short description here, do you feel that my bass sounded to boomy with the Vibrapods and that the less authoritative bass with the spikes is the right sound.
O personally seem to prefer the bass with my speakers on pods.

Tek thank you for posting this experience. My speakers are extremely dynamic, & that "gut-punching bass" is something that I'm so used to that when I hear a rig lacking those dynamics I really miss the effect; it seems to have so little PRaT.
My floor is tile on concrete, similar to yours. When I spiked my speakers I was very pleased with the result. However I also have a good assortment of Vibrapods & have wanted to try some #5's under my speakers, so thanks for the motivation! The fact that it was very difficult to perfectly align those spikes under my 125 pound speakers & then get them back into the correct placement has certainly dissuaded me from further experimentation, but it's something that I know I definitely need to try out, for curiousity's sake if nothing else.
When you hear a live band then those dynamics are obvious; this is many times what is lacking in a reproduced playback. Trust your ears above ANY measurements - go for what you like the best, it's that simple.
