As an alternative to the Vibrapod feet, or even for use in concert with them, there are the Vibrapod Cones which suit heavier items such as amplifiers and speakers, being weight tolerant up to 25kg. Some reviewers have pointed out that the improvements differ from vibrapod foot to cone, and that in some cases you might want to use both, stacked. Again, given the low price, no problem. There is no doubt that isolation works, and these are a neat solution.
