Tnanks, KN. Maple shade makes very nice looking stands and platforms, brass, etc. and look effective. Although I would not scrap my solid maple table/stands, the granite slabs I am using have turned out to be mostly a sonic bust. I now have prototype footers on the granite surface and under the ARC mono blocks, one footer under each of the seven rubber factory feet. I also have footers underneath the Wadia player's metal pucks that receive the factory points at each corner. My footers are my design, use two natural materials, and are still under development. So far, they have taken the massive granite slabs out of the chain of transmission, imparting a new plateau of clarity, so I know they are effective. I hope to release them to the audio community as a low-cost addition, to be used in conjunction with plinths, slabs, points, factory feet, etc. From the opinions here and industry approaches offered, a general isolation rule has emerged: At least two isolation methods using a variety of materials are necessary in an audio system.
On the draining of resonance.....
I have read of the importance of controlling resonance in components that contain motors and transformers. This seems to involve placing isolation points or bearings under components to attract or "drain away" micro vibrations, I suppose, of resonating frequencies. Ok--say this works, but hasn't the resonance already occurred as it is being drained away through the bottom of the chassis? I get the idea of isolating out airborne vibrations carried by the rack, stand, plinth, block, etc, but......really?
