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 know this might not be practical for most people but when I placed my Denon 51f turntable on my handmade console with a 250# granite top there was a very notable improvement from the 3/4" ply shelving it previously perched on. I say push the boundaries of normal and use some different materials. There I had my say! Good luck 
Has anyone used carbon fiber to set their equipment on? I noticed dragonplate has balsa sandwiched inside two layers of .030 carbon fiber. It looks like it would work well for smaller platforms (strength wise), but not sure how effective that would be. 
@boxer12,

Here I am. I’m a big proponent of carbon fiber. I’ve dealt with Dragonplate for years. Never tried their balsa products. I use carbon fiber extensively in my system. Plan on using it in my TT project.
I am not a fan of carbon fiber based on the sound of those Black Diamond Racing cones. They more or less kill the sound. No offense. They look cool, though.
