opinions please? IsoAcoustics stands vs GAIA footers under my towers?

“thicker and meatier” does not equate to better performance.  Sifting through online reviews the Townshend Seismic Isolation Podiums seems the best closely followed by Gaia footers.    I wouldn’t substitute which would likely yield subpar results compared to these purposely focused options.

If you really want to take it to the next level look at the Townshend podiums, in all the forums people that have tried both said that the Gaia's were very good but the podiums were on a whole different level better, When I put them underneath my monitor audio platinum 200 ll The sound improvement was as if I had gone to much more expensive electronics, best upgrade that I've ever done.

done Townshend

Iso has worked better for me

I also use marble pastry boards below the Iso's
