Isolation feet/cones for PS Audio NuWave DSD DAC

Not trying to be contentious but isn’t the question of DH Cones vs Herbie’s Tenderfeet also a question about the relative merits of vibration draining vs vibration damping/isolation?

I’ve read at least one "expert" recommendation to use both: a hard cone (brass in this particular article) under a component (point facing down) to drain vibration into a wood plinth and a softer elastomeric footer between the wood plinth and the equipment rack shelf to provide vibration damping/isolation.

I’m not arguing for or against anything here, just wanted to provide a slightly different context for considering the OP’s question.

Thanks, Geoff.  The DH site's shopping cart is out of service right now.  Anyone know if the prices shown for the various cones are for individual pieces or for a set of 3 (as sold)?  Might have to try some.  

Yup...the Golden Sound shopping cart seems to be down.  Curious how these things are priced.  See link here and scroll down to see their message about the cart.

PS - Music Direct has 'em too.  Price looks to be for a set of 3 (NOT per individual cone).  Pretty affordable as such things go.

@geoffkait - Did just that, Geoff.  Thanks.

Thanks for the Diament link, Randy.  I love the DIY option.  

Non-audiophile approved roller bearing alternative....

@bdp24 - Curious what you mean by "too soft"...
Too soft as in won’t adequately act as a conduit for vibration? or too soft w/respect to deformation under the load of a component??

If the latter, not sure that is the case. Each cup can support up to 500# (so the product literature says) and the cups are some sort of rigid, hard plastic, not soft rubber. I have on in hand.  Only the bottom O-ring providing "grip" is rubber.

I do like your concave drawer pull idea. Another possibility is an "acrylic dimple block" used for displaying baseballs, mineral spheres, decorative eggs, etc. The "dimple" is a concave depression that can accommodate a bearing. They come in various sizes.

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.

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.

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.  

Hello bdp - I appreciate the discussion.  As a sometime microscopist in the past (optical and SEM) I certainly appreciate how surfaces appear under magnification.  Given the apparent quality of the Ingress roller block products (it IS pretty looking stuff)  C$85 for a Level 1 set does not seem unreasonable.  

One thing that does have me wondering about the practical value of a more highly polished surface (not to mention added cost) is realizing this evening how cabling hanging off the back of a component likely interferes with free movement in both horizontal and vertical planes.  I wonder if this sort of cable "inertia" overrides the benefit of a surface that is smoother at a microscopic level.    

In the short term, I'll experiment with the plastic housings and stainless bearings.  Thinking the addition of a bit of silicone (or even lightweight spindle oil) will help "smooth out" some of the bumps.  We'll keep the Ingress products in mind, however - as well as the DH Cones.   

bdp - I continue to look for a low-cost, concave metal option. Meanwhile, these furniture guards are very hard. I doubt dimpling is a risk using 4 of them with the relatively lighter weight components I have in mind. A valid concern, never the less.

FWIW - the DIY bearing blocks are installed.  I have them under the pre-amp.  The set up looks a little "odd" due to height (Herbies Tenderfeet>> 1.5" plinth>>1.5" diam. SS ball>>Freya).  The movement the Freya displays when tapped from the side is striking.  It looks exactly as though it is suspended between springs allowing 360 degree movement in a horizontal plane.  

Gear had been powered down the last day or so, so playing some warm up tracks before listening "critically".  Might have to experiment next with suitable spring(s) to replace the Tenderfeet.
