Isolation feet/cones for PS Audio NuWave DSD DAC

The fatter jumbo is quite good but the more ballistic shaped Super is better. Usually three cones will be fine. It depends on what the underside of the turntable looks like. I can imagine four might be more stable or there might not be convenient places to use only three.

Many thanks. I like the idea of using the Super, they may also provide more stability. I'm using a Linn Axis, which uses "trickle-down" technology from the early LP-12.
  It has 3 stock feet, which offer no isolation plus a heavy aluminum platter.

Hello, @geoffkait ,
  I'm now using large DH Cones under my DAC and will be ordering the jumbo for my tube amp. Got a question for you; the component slides on the wood shelf when I touch the faceplate. Would using a thin layer of cork under the cone still be effective for draining vibration?
I know the Squares are available, but I'd like to save money to buy more cones.
Thanks.

The problem with using something between the DH Cone and the component or under the cones is that whatever material you use can and usually does affect the sound. While I do favor cork for some applications as a damper of micro vibrations I avoid using anything between the cone and component or under the cone since whatever you try will slow up the energy that exits the component via the cones. Even the thin adhesive backed paper disc that came with DH Cones a long time ago interfered with the sound and had to be removed. For under the cones those metal discs with dimple in the center might be OK.

@geoffkait, I noticed that DH makes Squares (Graphite based composition pad) and a DH Super Pad made out of the same material as the Squares to be used between their cones and the component. 
Do you have any experience with the Squares and/or the Super Pad?
