What isolation feet under your amp with great result?


I'm looking for more cleaner, micro inner details. Not tone control or dynamic.
Amp is 82-lb. TIA

Go to Amazon and buy yourself a box of a dozen hockey pucks for about 20 bucks. Place a puck under each foot of your amp and give it two weeks to settle in. I use them under my Pass Labs monoblocs and they work like a charm.
If they don’t work to your satisfaction... you're only out of 20 bucks.
Hockey pucks consist of vulcanized rubber.  In the audiophile world, rubber is not generally known for being a desirable footer material.  The vulcanizing process results in a rubber material with increased rigidity and durability, as well as other changes in the mechanical and electrical properties.  Many here report using hockey puck footers under their gear and speakers. Therefore, does the vulcanizing process result in a rubber material that has damping and support properties which are better than those of unvulcanized rubber footers?

I have no clue of the chemical or mfg processing properties of a puck.  
All I can comment on is that I'd tried several other footers in the past. 
Someone here on this forum recommended pucks to me. 
I tried them and liked them.  I sold my previous audiophile footers.
OP, suggest you research the following:

Barry Diament 
Ingress Engineering 
Townshend
Symposium
Stacore
Taiko
Machina Dynamica

For a diy solution read Barry Diament, buy Ingress cup/rollers combine with a slate or granite platform and a spring like Machina Dynamica or inner tube.

Other makes are ready made solutions that work.

Avoid rubber.
