Alternatives to Stillpoints

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?

I like Herbie's products across the board and use the iso cups and balls under my Primaluna mono blocks to great effect (on Himalayan salt block platforms).

Hey Andy,
Where did you get  Himalayan salt block platforms large enough for your mono blocks?
