What isolation feet under your amp with great result?

All footers have a sound, and different, dependent on under chassis placement. ***********Google = DRBMP-BLK-01 .......on Amazon....self adhesive rubber door stopper bumpers, 4 pack, designed to stop door knob, from damaging wall. I have used these for years, on all of my electronics. I find them to be Neutral, in SQ......Can use 3 or more under the gear, depending on weight of actual piece of gear ( in place of what feet comes with the equipment ). I have tried expensive footers, including sorbothane, metal, brass, wood, etc. and these, again, have less of their "own sound ". 3 packs will get you 12 footers, and free shipping, through Amazon, and as you might know, Amazon accepts returns with money back guarantee.....my prediction is, you will not return them. Under $10...for a pack of 4.

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.

@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.
