Best building material for vibration free shelving


I am building some built into the wall shelves for my VPI Classic 2 SE turntable, amp, preamp, CD player, and old Burwen TNE 7000A transient noise eliminator (that’s one for you old-timers to remember), as well as my DISH Network receiver box. The shelves must match in appearance the typical looking built-in wood bookshelves already in the room. The shelves will be located directly under my 45" wide flat screen television. They will be wide enough to hold two components side by side, other than the VPI turntable which will have the top shelve to itself due to its extra width. I will be building the shelves high and deep to allow for plenty of air circulation around the components. They will be painted.

My question is, what materials might you suggest building the shelves with to minimize vibration? If they were for books I’d normally build the sides, and top out of 3/4" birch sided plywood, the back out of 1/4 inch luan plywood, and the shelves out of oak to deal with the weight of the books without bending. I will be adding vibration damping feet under each component and am not looking for suggestions along those lines, only material and perhaps design recommendations to reduce vibration.

I was researching this last night online and on site, and saw recommendations to use four thicknesses of 3/4 inch High Density (HD) MDF, also to use granite or marble under the turntable, among other recommendations. I was wondering how birch veneered plywood would work too, as it’s ply’s, I believe, have their grains running in opposite directions. Maybe there’s some way to isolate the uprights from the horizontal shelves to reduce vibration transmission.

What would you think would work best for these built-ins. I’d appreciate any recommendations you have or your experience on this subject. Thank you for any ideas.

I have 2 maple platforms that need refinishing, I used one for my Scout and the other for my Prime.  The larger is 22 by 18 by 3 inches thick of air dried maple.  The smaller one is 18 by 15 by 2 inches thick of air dried maple.  I painted them black but they look crummy.  Need to be sanded and repainted.   If someone wants to drive up to me, they can have them. I will NOT ship them. Send me a PM
I agree with stereo5, solid maple is an excellent turntable platform, the thicker the better.
as weird as it sounds, I cut drywall squares and secured them with sticky wood veneer.
the best anti-vibration solution.
@skyscraper - I use...

for amp and turntable
- 3/4" MDF shelf
- 1/2" 18" x 14" granite tile (cut to tat size)
- with tool drawer liner in between them

Tool drawere liner like this product

I buy it from the dollar store - very cheap :-)

For smaller components (phono and Bluesound Node 2) I use 3/8" MDF and 3/8" granite tile with the same drawer liner between them

Each shelf has sorbothane between the shlf and the Rack;’s metal frame

My TT plinth is also made from 3 sheets of 3/4" MDF glued and clamped. It is very dense and does not vibrate - I would have to believe 2 sheets glued would make a very good shelf.

Each component is currently supported by 3 wooden feet like this...

The Amp and TT has the large feet, the phono stage has the medium feet and the Node 2 has the small feet

The wooden feet made a noticeble improvement in the size and precision iof the mage.

I have heard good things about Mapleshade product and their web site may contain some useful info for a DIY person

Hope that helps - Steve
I have 3" solid maple bought on here from lady in MI underneath both my DD and belt TT on top of a 1" MDF cabinet .I have tried ALL the usual suspects under their feet and found 6$ virapods best .
