I'm sure that there are various answers here, but i have used innertubes with the gear mounted directly on top of it, no platform. Using a "levitating" shelf underneath the component just gives you another piece to resonate or pick up vibrations, in my opinion.The innertubes are inflated just enough to lift the gear off of the shelf and allow it to rock very slightly. This uncouples the floorborne vibrations from being transferred into the chassis of the gear. This tweak works so effectively that i can literally do full tilt jumping jacks or STOMP in front of my CD and it doesn't skip a beat.
To "mass load" or damp airborne vibrations / cabinet rattle, I then have large (1 gallon) freezer bags of sand on top of each piece of gear. I typically use about 7 lbs of sand in each bag and remove as much air as possible. I know that 7 is the "perfect number", but it was also convenient. Sand came in 35 lb. bags, so this let me treat 5 different components with each bag.
I used freezer bags because they are both larger and thicker. I didn't want sand leaking out and getting into anything. Kmart currently has them on sale for $1.90 for 40 of them. You can also pick up all the other necessary goods that you need there too. I would look for either 12" innertubes for shallow gear (passive preamps, etc) or 16" for deeper gear (cd, tuner, amp, etc). These cost about $2.99 apiece and a hand pump is about $5 - $7 or so. A bag of sand should be under $5 or so. For under $30, you can damp and isolate 5 pieces of gear. I would consider this a real "blue light" savings compared to "audiophile" pricing on commercial gear.
Be sure to NOT cover vents or heatsinks on gear that gets hot (amps). Melted plastic and sand all over would not make your listening experience any better........ Sean
