What isolation feet under your amp with great result?

I have tried hockey pucks before, and the footers I recommended ( also from Amazon ) are, imo, superior......in place of the feet that come with the amplifiers, not in conjunction with them. BTW, for naysayers of isolation feet, isolation can happen inside the amplifier as well. If possible, isolate the power transformer, whether it be an IEC type or Toroid, from the chassis, using a product such as cork, a layer or two of Dynamat, rubber grommets, whatever, and it changes the sound, again, imo, for the better. The HK Citation 12, 16 and 19 power amplifiers all had rubber grommets of sorts, isolating the transformers from the chassis. So many other designs did not. Tube amp designers do not do this ( power and output transformers ), as it is beneficial, with sq, ime. Doing this, cleans things up a bit, an improvement, greater than a fuse change, imo ( and I believe in fuses ). Just saying. Be well, all.

Thanks for your insight....Interesting....My best Mrdecibel...

 I have order 3 sets of your footers.... Ridiculous price.... :)

I will try them when i will recreate my audio system....

@mahgister....when you receive them ( Amazon ships quick ), experiment with the placement of them under the component ( s ) before you peel, for the adhesive. In fact, you do not need to use the adhesive.....Enjoy !, and my best to you, as well.

three easy payments, I believe that ebm is describing to use the Critical Mass Center Stage as footers under the amp and, thus, between the amp and the Ultra Stealth platform.  That is the same method that I had described in the page 1 of this thread except I use the same brand (Symposium Acoustics) Rollerblock Jr + footers.  They are less expensive than the Center Stage footers and, IMO, provide excellent vibration drainage from the amp and directly into the Ultra platform.  You can contact Symposium Acoustics directly, speak with Peter (the owner) and he will provide excellent information and help to you.
Good luck.  Be safe and be healthy.  

For fun, I just ordered some springs yesterday.  I tried to go with something shallow enough so my amps wouldn't look weird and something wide enough for stability.  Regarding the spring constant, I ordered springs where the total weight per spring would be just a touch over one-half the spring's maximum capacity.
