Under speakers Vibrapod or Gaïa

@geoffkait    I'll check in when I'm ready to address speaker isolation.  Thank You! Your post was helpful.

GAIA are sold in sets of four. I'm considering getting a set of the model 2 (which support up to 120 lbs. when used in quads) for my Sound Anchor speaker stands, but they are a 3-point design. If anyone else needs only 6 GAIA's for his/her speakers (up to 90 lbs.), let's do what Wilbert Harrison suggested, and work together.

I use Vibrapods under my Klipsch Heresy IIIs and, perhaps since they're the proper "weight handling" versions, they work great. 

wolf_garcia ,  Thank's;  I was thinking to place a wood board under the existing vibrapods and add four other Vibrapod under the wood board.  So it will be twice decouple ?  Would it be better ?

Audiosens...maybe, as the main point for me anyway is to keep the speakers's vibration out of the floor which can act as a passive transducer of sorts...there's a simple test I demonstrate to my friends who pretend to be paying attention...play something bass heavy and touch the speaker box near the floor...feel that? Now touch the floor near the speaker...no vibes...now get me a beer...wait...forget that last part...for now.
