Isolation feet/cones for PS Audio NuWave DSD DAC

It's the marketing that is funny to me; 
"so advanced it's used in the aerospace industry and by NASA...
almost as hard as diamond."

Not sure why you find that humorous since it is the extreme hardness that makes the DH Cones more effective than the competing products. It is the material’s hardness that determines the efficiency speed of energy transfer. Thus, a relatively softer material - even metal - allows energy to be stored or reflected. The particular ceramic used in DH Cones is actually the next hardest material to diamond, and is much harder than brass, aluminum or steel, even tempered steel, as anyone can plainly see on the non linear Mohs scale of hardness, as I’ve noted previously. Nothing funny about that.

Yeah!  I think I may just try both at this points. If I like the DH cones better I'll move the tenderfeet to my integrated amp.

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?
