What isolation feet under your amp with great result?

the Herbies tube dampers are well known, his tall tender feet work very well at absorbing vibration and firm up the imaging 
for under $60 for 4 they are a $$ excellent buy.
i have used comes and bearing type in my system too analytical
sounding ,  they have cup bearing type also made of wood,and stone .

Symposium rollerblocks

My 72 pound Aragon 8008 BB amplifier has four tennis Balls under at the bottom a solid oak cabinet with plenty air circulation sounds great.

I replaced my Rega turntable feet with Symposiums Rollerback jr+, almost reasonably priced at a nice 20 percent discount, and I do think it changed the sound to the better, more clarity overall, but it also could all be in my head, but who cares it sounds better to my brain which translates into more happiness for me !

Regardless they upped the coolness factor of a really oddly designed TT. The owner lives 15 minutes from me so I can vouch for him amd his product. He's very approachable. And I think they have a return policy. 

Next I was advised to look at decoupling the speakers from their stands with Ansuz DARKZ but they are Uber expensive. Anyone familiar with that product?
