I know this doesn't address your question, but I recently tweaked my Pioneer 50" plasma with a DIY isolation stand made from 1 inch cast acrylic and 8 Vibrapods. All I can say is WOW!!! The total cost was about $100 and well worth the bucks. Huge gains in HDTV like video quality and depth. Under the isolation stand I use a Schroer and Schroer Focus 72 with the 5/8" glass shelves.
