I built an interesting pair of amp stands made from aluminum. They were two 1/8 inch pieces of aluminum with routed grooves in them. They were sandwiched together with marbles in the grooves. Then they were placed on top of tip toes. This is a very good sounding stand--but not a good idea if you have small children or large dogs that can knock the base plates off the marbles. The concept is similar to the symposium roller blocks. It disapates energy laterally (any mechanical energy from the amp itself) but couples it positively (vertically) to the floor.
