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

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.

I bought the Gaias and returned them. I suspect any difference people report is attributable to the effect of raising the speakers closer to ear level. In my case, they made the speakers too wobbly for my liking.
