I'd wait for "The Shelf" 3/4" thick 17"X15" or "The Source" 1 1/4". I use "The Shelf" under my CDP, TT, pre-phono and power supply. All my equipment is currently sitting directly on the shelves and all the shelves sit on Sims Navcom pucks. I had to wait to snag them one at a time but I think it's was worth the wait as I like the sound using the BDR shelves.
This is from BDR.
"Made entirely of BDRs proprietary Carbon Fiber Composite materials and finished with clear acrylic on both side.........., the BDR Shelf is massive and extremely non-resonant, absorbing enormous amounts of vibration: a BDR Shelf is only ¾ thick, yet it is 25x less resonant than an 8 thick granite slab and has 4 times the vibration absorbing power of 2 thick MDF!"
