The object of the exercise is to isolate component(s) from the shelf it rests on to preven vibration from being fed into the chasisis and innards of the unit via transmission. At one time sorbothane was deemed the ultimate damping material, until it was realized that sorbothane was essentially a spring system acting like a shock absorber. As such it had to be properly loaded to function properly. Picture a Cadillac using VW shock absorbers, and the VW with Cadillac shocks. The best way to reduce or eliminate the transfer of vibration is to reduce the contact area between the unit and its' support (shelf). Just about the smallest practical contact patch would be the point of a steel arrow point, as in archery. Replace the legs of the unit with 4 archery points and place metal discs uner each point to prevent it from digging into the shelf. If you are concerned with airborne vibration (you should be, the unit enclosure has 6 sides, why protect only one ?) construct a 5-sided enclosure of 1/2" hard maple to place over the unit with about a 1/2" clearance all around and the necessary notches to clear input/output lines & linecord. Cut a few windows, as required so displays, etc. aren't obscured and suspend it in the same way. "Awwww, but now nobody can see my very high-priced gear anymore!" So what are after, envy or the best sonics you can produce ?
