Not just another solid block of wood...
How they work
Each of the two hardwood plinths are coupled together with an air gap between them which is determined by the brass ring (fulcrum). The brass ring is centered within the structure allowing the wood to flex as you get farther from the ring. The interior of the ring and the 4 inch cavity in the center of the bottom plinth is then filled with liquid resin and sand which hardens like rock. This locks the two plinths together in the center while allowing the corners to move and actually absorb vibration.
The best way to couple a component is near it's four corners where the component chassis is stiffest. We offer our platforms with machined spots to precisely locate the cones for each of our amplifiers so there is no way to get it wrong.
As the vibration that is absorbed by the corners of each plinth travels to the center of the platform, the plinths get gradually stiffer until they become bonded to the composite resin plug that couples them into a co-mass layer damped structure with varying densities.
The platforms absorb energy equally from the bottom and the top instead of moving energy from both like a super highway.

The Optional CONES & PADS
For use with DECWARE amplifiers, we have created our own cones, made from hardwood like the platforms. These cones are brass tipped and designed to be placed upside down on the platform so that the tips locate on the highest mass
portion of the amplifier chassis. The machined holes locate the cones in the exact correct spot and are a diameter slightly larger than the cone so that only the bottom of the cone makes contact with the platform. The cones have a rubber ring to auto center them in the holes. The pads are made from sorbothane.
This chart shows the difference between the corners of the platform (violet) and the center (red). This is showing that the most flex occurs between 60 Hz and 120 Hz. It also shows how that energy is redistributed in the frequency domain from which one can calculate how much is missing as heat.
This chart shows the difference between the table (green) and the amplifier setting on the platform (orange). To see the difference between the amplifier setting on a rack vs. setting on the platform on the rack, watch the video below.

The Zen Audio Focus Clamp is sized to sit on top of the average full-size DAC / Streamer / Preamplifier. It pins it down with mass and helps to isolate the component chassis from external vibration as well as increase it's coupling to the plinth or component shelf. It uses the same technology as the Audio Focus Platforms except that it must lay flat on the surface of the component top without any cones, pads, O-rings, or anything other than the supplied felt pad. The top plinth, now unloaded, works by storing excess energy and working it back into the core over time until it eventually turns into heat.
The felt pad is used to spread the force out evenly across the entire top of the component -- this prevents flexing / dishing of the thin component top allowing it to vibrate. One side has the black polyurethane composite plug and the other side is just smooth wood. It works with either side up.
