Isolation feet/cones for PS Audio NuWave DSD DAC

Ah. Thanks Mr. Kait. Okay. No doubt those plastic floor guards won’t be as smooth as the Ingress Audio pieces bdp pointed out. For the price though, worth a try. Certainly at least on par with Diament’s wooden egg cup suggestion; maybe better with the application of a little silicone to the surface. That should help get things rolling.

Apologies to the OP for contributing to the detour the discussion has taken.  Hopefully some of this extraneous discussion will be of interest.  

@ghosthouse  all is good. In general I am really interested in DIY and the topics discussed.
In this specific case, given the responses to the effectiveness of the DH cones and their current price, I don't think its worth the effort.
For pure experimentation though, maybe.

The DH cones do seem like a good buy at current pricing.  I don't know for sure but the Taranis amp I'm running seems to have them for footers (as supplied/stock) OR at least something that looks a LOT like them.  I have a mishmash of inexpensive isolation treatments throughout my system.  After I satisfy my curiosity about this roller bearing thing, I might well get a set of cones to try.  Big bucks for me!  ;-)  but not in audiophile terms.  Hope they work out for you.

Just to note that’s it’s highly unlikely DH Cones would be found on any random component, stock or otherwise, unless they were glued there (unlikely), as there would be no way to drill a hole in the bottom of the DH Cone since, you know, it’s the next hardest material to diamond. DH Cones. Accept no substitutes.

Someone else had the furniture caster cup idea way before I did.  Just found this...

Maybe not DH cones under the Taranis, Geoff.  Does look like 'em though.
