I think the type of isolation platform you wish to purchase or build would depend on the type of vibrations you wish to eliminate. If you wish to eliminate room born vibrations then I belive you need some type of air suspension system. If you are looking to isolate chassis vibrations then some type of cone/sand loading may be better. I have my SFCD-1 resting on 10 pounds of sand which is contained in four zip-lock type plastic bags. The sand then rests on a piece of MDF shelfing supported by a 12 inch inner tube that is partially inflated. On top of the player I have about 5 more pounds of sand again contained in plastic bags. This works wonders for me. The total cost of this system is below 10 bucks. good luck
