What isolation feet under your amp with great result?

I've recently been replacing my feet under most components with platforms after much A/B testing.  Using a Symposium Ultra platform under my amp with great results. 

Isoacoustic Oreas, recommended to me here by another site member, work very well. Unexpectedly, they perform exactly as reviewers say they will. I never would have guessed that would be the case. There's a number of reviews online, and here’s a link to their site: https://isoacoustics.com/orea-series/  Good luck with your purchase whatever you get.

Black ravioli big pads under my Lyngdorf TDAI3400. Sound best after a day or 3 or possibly longer. About $80 each.

If you can find a dealer to lend you samples for a try, could be surprised...
my ARC Tube power amp loves isoacoustic absorption feet while my class A Luxman plays dull with them, it prefers symposium feet, improves dynamic and rhythm...Without listening sessions it is a wild guess IMO

Rollerblock Jr Carbide for me.
