Here are some of what I've done recently...
Equipment Rack of my own design. Each part has been isolated either by tips, cones, isolation platforms.

Post-shelf shot. Note sand-filled isolation platform on "tips" The power amp is also on brass cones on top of a similar isolation platform.
Rack version 2 will have spring-suspended shelves.
