I have used those under $500.00 audio racks, which do not improve your system's sound. I heard the Grand Prix is the best right now(friend of mine owns it) but I could not afford. I am using the Maplewood platforms under each components and could not believe they make a big improvement for my system. I will purchase a Mapleshade audio rack in the future since their Maplewood platforms are air-dried (huge soundstage). I would recommend you to try out by stopping by your local lumberyard and try to cut a couple platform and put under your audio components you will see if you like them. Good luck.
