Anyone tried military grade anti vibration feet ?

The Army's version of Vibrapods. Most likely too stiff for audio apps.

Hello nice thread ..I just purchased on a whim by shear accident a product called battery-last ..Its a gel sorbotane half sphere that isolates a boat battery.I placed them under a preamp and mulit disc player and they seem to work just like the expensive stuff for a whole lot less..

I have been very impressed with the economical Machina Dynamica Promethean mini spring supports.

I have the base of each spring resting upon a maple platform, and the top of each spring presses up supporting the flat bottom of a component already weighing enough to use a minimum of three spring supports

When trying these out I could not always fine tune the weight being borne by the springs as exactly as the instructions specified, nevertheless heard an obvious improvement compared to the variety of cones, rubber/cork shock absorbers, exotic wood blocks, and other support gadgets previously in use under every analog and digital component.

Very easy to position underneath components as each spring compresses without twisting, bending, or falling over as one adds "just one more." And, although I did not build any rugged industrial looking elaborate stacking systems as suggested on the supplier's website there is still a remarkable audible result to enjoy with a basic implementation using these springs.

Now that I have tested on each component separately, planning to purchase additional springs to permit use under every component at the same time.

Generally, you get what you pay for. Save money for Stillpoints Ultra SS or Ultra 5s.

I like the idea of the Machina Dynamica Promethean springs, but at $13 a piece, it's a robbery. Surely those can be had for a fraction of the price with some research effort.
