All depends on how you do it, size and thickness are factors and how the component is supported and how the granite, marble, etc. is supported. A very thick granite slab is just the ticket. I'm also fond of bluestone as a relatively inexpensive alternative to granite. People whine, well, granite rings when you strike it with a hammer. Well, then don't strike it with a hammer. Duh!!
All these materials, however, pale in comparison to real isolation techniques such as mass-on-spring, spring or monofilament suspensions, negative stiffness, things of that nature.

adds a great degree of brightness, no matter what the thickness employed. While the high content of quartz inherent with granite makes it very desireable for machinists planes (a flat surface used for measuring as the quartz is dimensionally very stable across a wide range of temperatures) the high quartz content serves to overemphasize the highs, as with excessive use of quartz crystal.
Just my observations

I suppose you could try damping. The big advantage of thick granite slabs is stiffness, i.e., resistance to bending forces. In addition to good old inertia. I have some big spring/granite systems out there under 30K amps with 3 inch thick granite slabs. They ain't bright.

I can not see making an installation overly complicated. Simplicity for me is a virtue, particularly if a simpler and better sounding solution exists.
Stu
Real isolation is going to be more complicated than a simple stand, no matter what material one chooses. That is why real iso devices such as Vibraplane, Minus zero, Silent Running, Seismic Sink, Halcyonics, Roller bearings of various types, Ginko platform, the one with many levels of glass plates, Relaxa magnetic levitation platform, of various levels of complication, have been so successful. Even for a simple stand one ought to give consideration to the type/material of feet under the stand and under the component."Everything should be made as simple as possible but not simpler." - Albert Einstein

Slate still rules, soapstone is a good alternative. Either will be a better choice even with something like my TMC legs.
Mine's got only one. Resonant frequency 0.5 Hz. Note decimal point.

thanks for the tire tracks!

Has anyone tried Acoustic revive quartz footer?
isn't it so expensive just for 5cm quartz?
I used quartz bearing under amp on walunt wood , it wasn't bad but i think
in my case "Rudraksha" was more natural (& neutral enough)!
I searched alot & couldn't find somone used them before!
It has interesting electrical property & hard, i am not sure could work in audio.
Has anyone tried "Rudraksha" too?

here as I never heard of rudraksha before, nor have ever seen a sample in person.
I do know that many objects react differently depending upon application.
Mike VansEvers was laying with various woods to use as footers, supplying a kit which had pieces measuring 1 by 1 by 1 and 1 by 2 by 1 and so forth also made from different woods
While I like spruce as shelving, it simply does not work at all as a footer. It is neccessary to use it cantilevered under a component for maximum benefit.
I believe the same may be work here. The nut may work well as a footer, but as I am totally unfamiliar with its properties, I can not say. All I can say is that if it works for you, that is the only thing that counts.

Thanks StuBetween some material ,it worked ( at least for me!). but i don't know much about properties .it used for health benefit in meditation culture of India .
And have electromagnetic , paramagnetic ,daiamagnetic ,dynamic polarity & inductive properties ... ! ! !
But may be , nothing to do with audio ?
I thought may be interesting for experimenting !I haven't any precise tools and electronic knowldge for deep experiment . !
Rudraksh found in many east asia countries and i couldn't find someone there who used it ( may be not worked or i couldn't find ).
thanks for other Christmas gift tweaks too ,good luck

a Himalayan store close to my home, I'll ask about it. Sorry I called it a nut, it actually is a seed from further reading (hey, I'm just a dumb American....). sounds interesting
Stu
May be a little more expensive in US but here , near
the himalaya , it is unknown & rare too !!
I hope it would be useful , ( but at least is energizer for body ).
