@goofyfoot - For years I believed that the best way to isolate my components was to install some type of absorbing material, like sorbothane, between the shelf and the component.
Then on one thread I read about cone feet. I started with various sized wooden cones and to my amazement the sound improved
- improved clarity and details
- improved bass textures
- the theory is that it "drains" unwanted vibrations from the component
I then read a post that one member recommended brass/bronze feet
And on a different forum about how to isolate components using a "sandwich" of materials under each component
For each component I now use
- bronze feet of different sizes
- these were custom made at a machine shop in my area, so the end product was quite reasonbly priced
- sitting on a granite tile
- with foam drawer liner between the shelf and the tile
- here’s a link detialing the approach on my web site
The result is stunning details, exmpansive imaging and excellent bass performance and textures
Hope hat helps - Steve
