What isolation feet under your amp with great result?

I just completed a partial virtual system page update including a shot of one of the SMc amplifiers that is supported on springs (you can't see them) over the SRA platform, which is sitting on a low-profile Sound Anchor stand.

@squeak_king_77 - thanks for posting that info on the carpet discs.

@mitch2 - your system page look great. Is that a woolen rug on your wall behind the speakers? Did it make a reasonably significant difference in room sound?
I was thinking of doing the same thing, but also maybe having it stood off the wall a few inches so sounds can pass through, bounce off the wall behind and make a second pass.

I'm using the Symposium Acoustics Ultra Platform under my integrated amplifier with very noticeable results.  The sound is more focused and the background though very good to begin with seems slightly darker and the tonal focus seems better.  

I also have Symposium footers underneath my CD transport and speakers.
