Under my tower speakers -- Isoacoustics Gaia, other options?

I use an anti-matter reactor system that keeps my speakers about 2" 

above the floor surface at all times. I have found this to be 

the best way to eliminate all unwanted vibration. Available through

our friends at area 51.

Of all the tweaks/upgrades I’ve employed in my systems, the Townshend podiums made the largest improvement, by a wide margin. They are transformative. Highly recommended 👍🏼

I used an inexpensive cork/rubber disk to little effect.   Then I tried the IsoAcoustics Gaia II and was amazed at the difference.   I’ve got hardwood floors upstairs and vinyl tile/carpet over cement on the first floor.   In both cases the Gaia II footers made a noticeable and pleasant improvement in the sound and soundstage depth. My speakers are XStatic EC/X, 40lbs each, used 4 footers each.  YMMV.

Gaias are very good but Townshends are better.

Here you can find a paper about coupling or decoupling speakers (in french but Google Translator will turn it into english).

On concrete floor : the best solution is coupling spikes .... but the good general cases way to carry loudspeakers is to use LOW THICKNESS, HARD (requires a low damping factor) DAMPER (rubber) rubber/hard polymer feet less than 5mm.
