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.

I have done many experiments in this area. Most people have been so conditioned to believe speakers must be spiked that
they dismiss outright any suggestion of using vibrapods or
bearings devices even though they have never actually tried them.

When using vibrapods under speakers you can simplify things
by getting 20x16 or larger glass cutting boards and then set vibrapods/speakers on top, and you can easily slide speaker on carpet/wood floor. Also 1" nylon dog leash makes good strap to loop under large heavy speakers so 1 person can lift/move.

Once you have speaker on vibrapods you will easily hear deeper more detailed bass lower midrange, however with some speakers/music it can be too much bass emphasis and not sound natural, this is mainly with bass heavy rock music.
I really like vibrapods with classical music as it brings out bass details on viols, bassons, deep horns etc. When speakers are on spikes there is shift to upper mids and treble and bass becomes tighter/leaner which may be the sound you prefer. So depending on speakers you have may like the vibrapod effect, you should try this if you feel system is currently bright and needs less treble emphasis and more bass.

The lower mid/bass also becomes more detailed with vibrapods
I feel vs spikes. I especially like using vibrapods with stand mounted monitor speakers that by design are lacking low bass response, really works wonders here.

There is also half way step between vibrapods/spikes and that is with oak blocks (cut from 1/2 x 3 trim boards) you can try. Also since bass is omni directional you can vibrapod one speaker and hear the basic effect.
