NORDOST SORT FUT VS. ISOACOUSTICS GAIA

Sounds like a big pile of BS to me too. The GAIA II made a huge difference under my GE Triton Refs,

The website of Critical Mass doesn’t look good to me too. The footers appear to come without threaded holes for speaker installations hence I’m not sure if they can be used for speakers.

Similarly the Isoacoustics Gaias work wonders on my Marten Dukes. As such, I’m now an advocate of proper isolation for both components and speakers. Read "proper",  not BS.

I use gaia under my large tannoy 15 speakers and the difference before /after was amazing. Yes pricey but you get an amazing upgrade for the money 

The Gaia not only work but look great as well. Pricey yes but worth it from my perspective. Used them for years. 

Critical Mass is NOT for speakers components only.

Absolute Sound did reviews of critical mass, Nordost sort fut & compared it with something else. Very informative. CM worked very well but took time to break in & the Nordost produced positive results but not as much as others, was the stripped down conclusion. Reviews probably available online.
