stacked equipment isolation?

hello. due to space restrictions i need to stack my dvdp and my int. amp. it is mid-fi at best but i want to hit all the points(power, vibration, acoustics) within my system before beginning the next wave of component upgrades. might anyone have suggestions on what to put in between each component? lets try and keep it between the posts, i.e. vibraplane and dayton cones. i was thinking maybe cardas cuboids. thanks, d.
