Sorry; I'm in desperate need of an amp stand (currently sitting on a rug).
Not sure if granite or marble would be good choices reducing vibration ; before I order one cut from a local prefab outlet (kitchen counter top makers).I'm thinking having either holes tapped and fitted for inlets to support spikes or simply create a plinth (with feet/spikes) in which the granite/marble will be placed upon.
Any help would be appreciated; been a while since I've visited the DIY forum; have had many great projects from here in the past..
pic of my components currently 'slummin' on the floor..
may the bridges I burn light the way...

never heard of it but looks intriguing; and quite purty to boot!
$59 iron wood cutting boards
Well in any event, this looks like this will be a realtively inexpensive project be it stone or wood product; thanks everyone for your contributions :) ! This is by far the best forum on AA (IMHO)

Thoughts??
Come to the Darkside. We have cookies.
If it is ipe (Brazillian ironwood) and it looks like it might be, I'd recommend against it. I had some leftover ipe from a deck project and figured that because it was so dense and heavy, it would make good armboard material for my JMW 10.5i tonearm.
Totally deadened the sound. I mean it was really weirdly bad-sounding.
The amp stand is on top of doubled up rubber bottle stoppers so i can run the Pangea power cord under it from behind... and the interconnects too. because the rubber bottle stoppers make it tall doubled up, i have like eight pairs under there so it does not wobble
I like it. Cheap, effective.

Ooops. Meant quartz, but read the brightness caveat later in the thread.

Granite adhere to neodymium magnet too!
What about sandbox ?
shelviong I have found is spruce. I have been advocating that audiophiles take a lesson from instrument makers who have been experimenting with materials for centuries. Spruce is the favored material for piano soundboards, and that instrument has probably the greatest range of any instrument ( well, maybe excpet for an organ). It is also the favored material for the soundboard of a harp as well as the tops of violins, guitars and other stringed instruments.Some will proclaim that the use of spruce is merely adding euphonic distortion. Definitely not so: finer nuances of the performance are more readily heard and a more natural tonality is put forth. This works with solid state electronics as well as tubed.
The picture is of a spruce shelf made from an old piano soundboard that I made. The spruce is simply butt jointed and the ribs are laid 90 degrees to the planking. This one was from a 1901 Steinway, BTW: the soundboard had developed too many cracks and needed to be replaced.
Implementation is the key. You can not lay the spruce flat on another support: it will spound very dead. The spruce must be elevated above the existing shelving and the weight sort of cantilevered upon the shelf. I have used simple spruce planking and achieved the same effect. The spruce support must be at the far edges of the shelving or planking. Of course for your amp at least a one inch thick spruce plank would be necessary.
Use of spruce in this manner creates a most organic sound quality, one which when implemented under digital components can elevate their sound to vinyl status.
Of course. YMMV.

I just did a bit of research and found a Japanese hardware store in downtown LA that carries spruce cutting boards like the one pictured above. I may have to give one a try or perhaps find a wood supplier that carries spruce.

for $59; spruce; and even has it's own legs
Unfortunately it would be too small for my amp-

Go is a board game played with black and white pebbles and is sort of akin to chess, in a way, being a game of strategy and conquest.

a German company making speaker cabinets out of spruce. Haven't heard them though. I believe they also make racks of spruce also ( but being German, a bit pricey). A CES exhibitor told me was favorably impressed with a Japanese speaker which mounted the speaker in a guitar body ! I am assuming that body had a spruce top....
You can buy spruce planking or bracing boards from many lutetier suppliers.
A couple of pieces will suffice as long as you elevate the planking above the shelf.
stu
Sorry the holes are from the mounting points for the piano strings, and a crack is clearly visible, the reson why the soundboard ws changed in the first place. for the curious, it is from a 1901 Steinway.stu

The amp stand itself is a Salamander model that can be bought at Audio Advisor. Raquetballs in cups and a 2" maple block finish out the setup.

great information given.

Marble or ceramic tiles (stacked to improve stiffness and build up mass), 5 Herbie's thinnest grungebuster dots between each tile, the whole nine yards up on stiff hardened steel springs. One inch tall compressed, the springs are very stable even with high center of gravity loads. Target load for 3 springs 30 lb. Resonant frequency of isolating system 2-4 Hz, depending on direction. Total cost per stand circa $65.

I love ceramic tiles too!! Nice setup.
I like Geoff's set-up. Forget exotic precut wood - too expensive - and not as good as marble or ceramic.
What also works well, is an adobe block. When I lived in NM I used adobe bricks under my Quicksilver monos with good results. And they were free!
Has anyone tried granite? Tweakers are using clear and smokey granite discs with some success. I'm thinking there should scraps available from kitchen counter installations at a reasonable price.
Clear and smokey? Oh, you mean like quartz. I don't think they make granite in clear or smokey yet.
minimum 6mmx6mm makes a more non resonent base. Expensive unless you buy direct from a glass processing shop.
I'll take unclestu's recommendation of a slate platform with spikes and add a J.K. Adams BRIN-1915 hickory board to position on top of the slate platform, with a set of six Herbie's Audio Lab grungebuster Dots (1 inch diameter) placed between the slate platform and the hickory board. Furthermore, a set of Herbie's Audio Lab Iso-Cup with SuperSonic Hardball footers positioned directly under the amplifier would be a must have in my book.
slate is a better choice, IMHO.
stu
slate is the best, butcher block good, marble and granite are not good.
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.
"No matter how much you wind up with in the end you would have had even more if you had started out with more." - old audiophile axiom
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
Stu
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.

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?

Edits: 01/12/13 01/19/13
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 ).
