Isolation feet/cones for PS Audio NuWave DSD DAC


Hey all,

I am debating between Large DH Cones and Herbies Tenderfeet.
Anyone have experience specifically with this DAC?

Thanks!

Regarding the DH Cones:
Why is it suggested on the DH site to have the rear two cones with the larger base down (on the shelf) but the front cone reversed with the smaller end down and the larger base under the compoient?

What I found is that tips of all DH cones should always point down. Same for any cones. It doesn’t make sense to point any tips up since that would tend to prevent energy from escaping the top plate or component as well as transmit structural vibration more efficiently. I.e., the diode effect. The other part of the suggestion you refer to that I disagree with is that the third cone be placed so as to make the component slightly unstable.

Speaking of cone tips and hardness, I got a set of the original Mod Squad Tiptoes when they were introduced in the 1980's, and installed them under my 140 lbs. apiece loudspeakers, with steel discs under them to protect my hardwood floors. It didn't take long for the tips of the soft (aluminum) Tiptoes to become flattened. Oh well, nice try.

The DH cones work especially well under my Townshend Rock Elite turntable (even better than those by BDR), whose unsuspended plinth is an upside-down steel frame (like a rectangular cake pan) filled with plaster-of-Paris and bitumen pads---very non-resonant. The p-o-P and ceramic cones make a great coupling
