The quote does indeed make sense.
I used to have a 6" sandstone base for my equipment to rest on. The problem as described to me is the ability of stone to "store" low frequency energy (high Q) and release it at unpredictable times. The same effect applies to wood shelves and wood racks, only at a higher frequency. In both these cases it's the large low frequency waves that cause the problems. The high frequencies are a different problem, mostly vibration from within the components and high frequency vibration from the air and frame. The concept of light rigid racks vs. shot or sand filled racks is to first stop the high Q. The high frequency would remain an issue, but is much easier to deal with. The old concept was to reduce the flow of vibration by using down turned points. The idea is cones will "drain" the components internal vibration and limit the vibrations coming from the shelf by only allowing the point as a conduit. I believe this is still a valid concept, and I continue to use cones on my amps (large transformer vibration).
The entire concept of the Neuance shelf is to absorb and disperse a large band of vibration frequency within it's foam core and thin rigid skin. The core has differing densities from the surface to the core giving it a low Q factor. The problem with Neuance is it's limited in it's low frequency performance. This is resolved with the light weight rigid steel rack It has low mass, thus it does not absorb or transfer low frequency vibration. The concept of the bubble wrap is to completely isolate the Neuance from any frame vibration. With the even weight distribution I believe the Neuance is able to preform more efficiently by not having the point load/ density the support spikes would cause, plus the shelf is not asked to absorb the frames vibration.
The concept of isolation is the same as used in the "bearing" support products. I have limited knowledge of these products but I'm evaluating them now. The concern with these products has been that they allow the component to move while releasing the inner vibrations. The fact that it is able to move gives the same isolation as the bubble wrap, but the movement could cause smearing of the leading edge of the note. Thus the incredible celerity I've discovered could be lost. Other air suspension concepts may also allow movement, again something we want to avoid. As I stated in the original post it appears to me the bubble wrap is not allowing any movement.
The concept of bearings used to isolate the floor (a huge low frequency vibration plane) from the speakers seems to hold the greatest promise. This is the focus of my trials right now. I will later try some different set-ups on the cd player to see if it performs better than what I now have.
I should also say that metal supports, cones and bearings tend to add a tonality to the sound. I have found titanium cones to be the smoothest with the least coloration. One concern with the bearing products is this very issue. This is why they offer high-carbon steel bearings, this could help tune the sound out of edgy. I'm trying different isolation from the bearings with wood, MDF and Black Diamond Racing pucks. The pucks are used with my reference speaker set-up in combination with BDR cones.
