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 remember the first time I heard his smaller speakers-it was 2017. I was more impressed by the sound that they were making than anything else in the Capital Audio fest. Of coarse he was running Audio Research gear- Ref 6 preamp and the 75 ref amp, and it was glorious. And honest guy. It was the real deal. If I could afford it, I wouldn’t hesitate to buy from him. I have just never heard any real flaws in his products, they sound fabulous.

Easy, isolation under each gear. I don't have stone racks but do it nevertheless. They are plenty of choices, springs, soborthane, isoacoustics, etc...
