Did some reading up on these and took a chance (money back guarantee). Bought directly from Stack
and coudn't be happier. Had Gaia III on my Dali Rubicon 6 and while liking them got the bug to try the Stack.
They literally give the instruments a more solid feeling. Yes I said feeling because the notes seem to be
coming from a more defined instrument. It really is kinda spooky how these things work. Prior to this puchase
I was thinking about sound treatment for my room particularly behind my chair for dispersion but the 100 has
removed so much from the floor and everywhere else I don't feel the need. I'm really liking them.

I've never tried the Stack Audio's AUVA's, but from what i've read they perform better than their EQ iso feet. An audiophile whose ears I trust told me he a-b tested the Stack EQ's and AV Room Service EVP's under his tube gear, and preferred the EVP's. But back to the AUVA's, I'd rate them higher than Iso Acoustics feet, but below Carbide Audio Base feet which are the best imho. But the Carbide Audio feet are pricey.
