"Your set of eight review footers are the standard Nano. My original plan was to send the diamond version but after feedback from your podcast with John, I think the standard version has potential to reach a much wider audience at its price. It would be easy to send out some diamond versions if you feel like trying those too. I recommend using just three footers unless the equipment is extremely heavy or has a very high centre of gravity where stability could be an issue like a tall loudspeaker. Because there is just one bearing inside, the tops of the footers will tilt to the sides while at rest until the component is placed on top. Similar to your Carbide Base Diamond footers, some adjustments to the positions of the footers might be necessary so they move around freely. When you tap the equipment, it should swing slowly. Because of the low rolling resistance the equipment wobbles around seemingly endlessly. It's pretty cool to watch. The slow oscillation speed is indicative of the low 2.5Hz natural resonance frequency. This is possible due to the shallow curvature and lack of indentation in the bearing races. A low resonance frequency ensures effective isolation of low frequencies."

"I decided to call the footer simply Nano since the design is quite a bit different from the other two footers. I forgot to mention that Nano is machined from non-magnetic i.e. austenitic stainless steel. It won't magnetically interfere with sensitive electronics. Nano can optionally accept spikes. On our Carbide Base footer many customers report better sound with spikes. The ultimate Nano configuration is with three of our TwinDamp spikes installed as shown right above. This adds an additional $72 per footer. The stainless steel spikes are $21/3. Nano can optionally bolt to speakers in lieu of spikes; or under equipment in place of stock footers. You can pass a bolt through the bottom of the outer housing so that it screws in first. Then you screw the Nano insert into the outer housing so that it points downward. Most standard bolts can be used. We sell a bolt kit which includes screws in common sizes for 8 footers for $19. Another feature of Nano is that the centre insert may be added into the other two footers. When screwed into the centre hole, the top of the Nano insert protrudes from the top for equipment to rest on on. [See upper right black footer.] This is a lower-cost alternative for adding the additional isolation stage to the standard Carbide Base or Carbide Base Micro."

"The differences from the Sapphire and Diamond versions of these footers are that Nano's ball bearing isn't quite as large and spreading the load across three rather than one bearing per footer will reduce the indentation of the raceways. But otherwise performance should be similar. The Nano insert can also be added into the Sapphire and Diamond versions of the Carbide Base footers to further improve isolation. When multiple isolators add together in series like this, it pushes down the natural resonance frequency thereby providing even better isolation of low frequencies. The tradeoff of adding Nano into other footers is that max load per footer becomes 55kg ;and because the centre hole is now occupied, the footer cannot bolt to equipment nor support the tip of a spike. The footer must support a flat surface and at least three must be used. The standard Nano insert is $59 each and the Nano Diamond insert is $179 each."

Just as my squad of vibe-killing minis cleared Dublin customs, HighFidelity.pl published their review on Jeffrey's big Diamond bases. Because I'm not infallible, know everything or have access to all, I enjoy learning how colleagues rate things I'm super impressed by. "The Carbide Base footers are a great product and the best anti-vibration isolators I've tried. Our Polish competition from Divine Acoustics and Pro Audio Bono is beautiful so I'll stick to what I use daily. But the Americans go a step further. They add sophistication and depth through excellent resolution. They energize the soundstage by filling the space in front of us with strong, extremely coherent and smooth imaging. Yet outlines remain perfectly legible. They're simply not marked as separate entities but remain part of the overall sound field. These are isolators for the best systems extant. They will bring out more warmth, softness and fullness and add a lot of clarity in the bass. They do this without boost because they don't work as a quasi shelving filter. They simply increase the band's detail density. These truly are outstanding products. It's why I decided to keep them in my system, one set under the Ayon Audio Spheris III preamp, the other under its power supply."

Hifilutin nipples of Venus? It's apt relative to size. Biting into them would chip if not crack teeth so stick to the famous baked variety for that. The included bolt set includes the four sizes shown; and black inserts for the three thinner bolts. It's how we can replace component footers or speaker spikes with permanently mounted down-facing Nano. Because the ball-bearing insert sports long threads, there's plenty of height-adjusting leeway to correct for crooked floors.

Seeing and handling Nano telegraphs flawless machining and polish to convey pride of ownership over a product of obvious quality. Making the nipple portion retrofittable to the bigger inserts is an unexpected bit of clever trickery. It adds an optional extra stage of isolation for extremist applications.
