@thyname: When it comes to vibration control, everything matters.

Totally agree @yoby

The little blue foam center with tread top and bottom. Useless for audio. Way way way to stiff. maybe drilling a gazillion holes in the foam might get them to flex some. They clearly are designed for multi- hundreds of pound weights. The vibrating air cleaner I placed a dozen under?  The wood below is vibrating just as much. So total fail. My butyl rubber bottle stoppers are way better.

Good to know Elizabeth as I was considering buying a set to trial.

I received an order from Herbies a few days ago and my results are puzzling.
Bought 3 isocups and lamp black balls to place under my Ayre ax7e amp.

So placed under the chassis bypassing the existing 3 feet wrought a slight increase in depth and bass.

However placing under the existing feet gave a considerable change! Much improved bass and top end, almost like I had hit the loudness button...lol.

I thought the idea was to bypass the manufacturer supplied feet and go direct to chassis.
Tbh I was truly surprised to be really hear anything this noticeable. And I swapped back and forth many times just to be sure at least in my mind.

Any thoughts?
