Discussion on Isolation/Coupling of Equipment

I am starting this thread in hopes of creating a constructive discussion on different equipment rack/platform designs, and the different ways of dealing with vibrations and resonances regardless of their origin or their orientation (in 3-D space).

Many feel isolation is paramount while others preach coupling. When is either appropriate? How is any of this accomplished? Which materials and/or designs work better than others? I wish to include the various cones, blocks, Sorbothane feet and so forth in this discussion too.

I am genuinely interested in forum member’s experience. I have not experimented much with different racks or platforms, so I’d like to hear what others have noticed and observed.

I have read through many articles and advertising text on the subject, most recently the Sound Star website:
(http://www.audiopoints.com/livevibe.html)
as well as the interesting points made by Mike Van Evers’ back in 2000:
(http://www.stereotimes.com/comm0200a.shtm)
both of these discuss vibration and resonance control.

Does anyone else have some good reference reading links available?

Thanks-
