I'm considering various options for isolation racks and stands. Current options include the Townshend Seismic Sink Stand and a not-yet-available unit from Critical Mass Systems. Also the Solid-Tech Rack of Silence.
Problem isn't too bad since the 12" woofer fires towards the side walls, not toward the equipment. I can't feel the equipment vibrate at all regardless of bass content or volume. The dCs "stack", JRDG amp, and P1000 each weigh about 80-100 lbs and have well designed chasses (particularly the amp).

Check my system page for room treatment details. The ugly eggrate foam is temporary until I decide what display system I'll be using. Considering the new Samsung 70" plasma and Qualia 004 projector (both true 1080x1920), or waiting until there is a 1080p DLP front projector which will be towards the end of the year. If I go with projector there will be room for a 92" diagonal HDTV screen.
