Best building material for vibration free shelving

@boxer12,

BTW, I have a 2'x4' sheet of 1/16" quasitropic carbon fiber in my shop that I plan on using in my TT project I bought from Dragon Plate years ago. The motor enclosure and the platter's plinth will be layers of aluminum, carbon fiber and purpleheart. I know, there is a chance with wood...it's contracting/expanding with temperature changes, but I've had this wood curing in my house for years to try and minimize this. We'll see. This is what's fun about DIY?

Great advice slaw! Thank you very much

Oops - I think I may have missed responding to a couple of people ...

@n80 ...

williewonka, I made some feet for my preamp out of walnut that I had lying around. The rubber feet of the pre-amp sit in the little divots on top, the wood blocks sit on 1/4" sorbothane pads. Does any of this make any difference? I have no idea. Kind of doubt it, but total cost was about $12.

I originally had sorbothane on some DIY feet I positioned under the components foot, but after trying the same feet placed directly under the components case I found the image became much more focussed and larger, with more clarity

Steve (Williewonka), After reading your suggestion, I might try using my piece of leftover marble, and set it on the top shelf under the turntable with a piece of tool drawer liner, or constrained layer damping in between, once I figure out what that is and how to get it., Thanks for your ideas.

There is a company that builds shelves for components racks that utilize the constrained layer damping for their shelves made from foam filled stainless steel - but I have forgotten their name.

Here’s one that makes complete racks

But since I am all about using  an affordable DIY approach I found the tool drawer liner "sandwich" approach to be very effective - but the above rack does look very nice :-)

I also take a similar approach with my speakers because they are on carpet...
- Speaker has cone feet and sits on a ceramic tile
- then a layer of drawer liner under the tile
- then a granite tile with one of the multispiked carpet protector feet at each corner

I didn’t want to allow the speakers coned feet to penetrate the carpet/underlay

It is a very stable solution once the carpet and underlay compresses, which takes about a month - my speakers weigh around 50 lbs each

WRT cone feet - I have had a chance to experiment a little more and found the position of feet makes a difference e.g.
- my amp has a foot either side of the large transformer and the third foot positioned for optimum stability
- my phono stage has one foot under the transformer, another under the circuit board and the third foot positioned for optimum stability
- My Turntable - was a little more complex - please see

I only use three feet - for stability

The larger feet are not attached to the component - the component simply rests on top of the cones

The smaller feet however, are attached with a piece of double-sided tape.

Hope that helps - Steve

Hey @skyscraper,

Have you made a decision yet?

Bamboo is vibration absorbing and pretty cheap too. I use bamboo chopping boards under my components. They come in various sizes too and are stocked in a lot of places which is handy.
