Gaia do magic to my speaker

Explain the flooring under the speakers; suspending hardwood, carpet over wood, carpet over concrete, etc., etc. Without these details the discussion is pointless.

I think he is saying that $600 in footers made a huge difference. 

If the elevation of the speaker changed due to the footers, imo that is THE biggest reason why the sound seems better. Even seemingly small changes in elevation of the speaker can seem impressive.

My system is in the suspending hardwood.

The above photo was taken before setting up Gaia.

The elevation of the speaker did not change much, less than 1 inch after changing the shoe.

Before using Gaia I had used the other isolating cones whose name I do not remember.

Something to remember when trying these isolation devices, footers, spikes etc:   Changing the height of the speaker in of itself, even by a tiny amount, can change the sound for the listener, as it changes the angle of the tweeter/drivers etc relative to your ears.    So it's possible the change in sound you are hearing is to some degree the altering the height of the speaker.    And the degree to which this will change the apparent sound of a speaker is going to vary between speakers, depending the general design, crossover design, etc.    Some speakers will be more immune to changes in height than others.

I've played with altering the height of my speakers and it usually alters the sound, whether it's actual spikes, footers or books/magazines/block of wood.

FWIW: I briefly tried some isoacoustics pucks (same principle as the Gaia) under my speakers and found the sound actually a bit "off" lusher, but darkened the tone, less alive sounding, and I preferred my speakers without them.    Which isn't of course to say other people won't have different experience with them.
