Steve,
My ideas on isolation? This will anger a lot of folks but here goes. Best: Concrete floor, rigid stand(s) with spikes, 3/4" MDF shelves. Second best: Wall mounted 3/4" MDF shelves on a load bearing wall. Turntables should be isolated from other equipment by having their own stand or shelf. The only thing one needs to worry about with this concept is airborne vibrations and that can be minimized by strategically placing the speakers in relation to the electronics.
I certainly believe that anti-vibration devices can work and are desirable for tubes and CDP's. I question the use of glass in thicknesses of less than 1/2".
I'll share a little trick I learned 30+ years ago to check vibrations and it's cheap. Buy one of the laser pointers and tape it to a tripod which is placed on the ground outside of an open window. Use double sided tape to attach a very small mirror to the item to be checked for the effects of vibration. The goal is to reflect the light to a surface as far away as possible. Watch the reflected beam of light with and without music and you will observe the vibrations.
As for glass, do this test on an exterior window as far away from the music as possible. You'll see instantly why glass is an audio no-no.
