Improving a stone rack

Hi all, I have a large stone rack for my system, in beautiful granite, which works great for stability, but maybe not so good for other aspects of the sound. I wonder if it contributes to some treble ringing and harshness. I want to improve the sound, thinking of felt damping on the wall behind the rack, some form of cloth to cover the reflective surfaces of the shelves, and adhesive rubber type mats on the bottom of the stone shelves. Is this the way to go? Experience based advice is very welcome. My rack weighs a ton. It is not easy to compare to a wood or composite rack. I need advice on how to counter the sound problems of stone or similar polished surface shelf racks. I want to try this, before I consider a new rack or shelf arrangement.

I have a granite amp stand. I found it effective to place vibrapods (there are many alternatives) under the granite to isolate the slab, then springs between the component and the slab. So, micro vibrations do not get transmitted into the slab from the floor and the component is isolated from the slab. Obviously a vibration platform would be even more effective than the springs.

Yes, I was, my first career. Lots of folks from the department went to Skaergaard. This was in the mid 70s when they were just unraveling the sedimentary features of the crystals inside the chamber. Crystal turbidities and the chemical differentiation / substitution inside the Felspars, olivine, and melt etc.. I was at the U of O where lots of this research was going on.

 

But the first gabbro complex I used to climb around on was the Duluth Gabbro Complex. You just never forget your first gabbro complex.

I was fascinated by peridotite. And then, of course, serpentine exposures around the world. So my countertops are all serpentinized peridotite now.

I wonder which gabbro complex they got it from, Skaergaard, Bushveld, Muskox, Duluth?
