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.

Your personal preference should probably be the judge. If you want to test which is closer to flat response, get a Radio Shack SPL meter and a test CD and measure it. Warning: The Radio Shack meter is somewhat off, but Sean published a list of the proper correction factors a while back which should bring it into line. If you search the forums, you will find it.
