Here is some info for Critical Mass Systems. Joe Lavrencik is a great guy and has had some impressive CES showings with Joule-Electra, Elrod, and Vandersteen/Avalon. Steve Huntley at Great Northern Sound is also a big fan of Joe's work.

This platform is the bird's eye piece Joe did for me. I have four of them.
You should also consider products from Gran Prix Audio and Silent Running Audio.
