Marc Phillips at Part-Time Audiophile has published a review of our Carbide Base footers. Marc performs multiple experiments with the footers under his speakers and electronics, noting:
I really enjoyed playing with the Carbide Bases and seeing how they could improve–without question–the clarity, transparency and overall performance of my audio system. Highly recommended.
We are honored to receive the PTA Reviewers Choice Award.

Now offering optional spikes for our Carbide Base footer machined from our TwinDamp™ material.
TwinDamp™ is based on a manganese-copper twin crystal alloy which has a damping capacity higher than magnesium and 10x that of copper. It has a loss factor similar rubber but in a rigid metal form.
We then perform multiple temperature treatments utilizing our high temperature furnace and cryogenic freezer over a 2-day period to further improve sonic character. Read more about the performance benefits of TwinDamp™ in our Measurements section.
All of our products are designed and manufactured in our company headquarters in Texas. Below is a video showing various stages of machining of our Carbide Base footer in our CNC machine shop.

Dawid Grzyb at HiFi Knights out of Poland has published a comprehensive review of the Diamond version of our Carbide Base footers. Dawid writes on his listening experiences using the footers under his preamp:
Elevated O2 content, increased imaging size, wider dynamic range and sensible instrumental/vocal closeness were uniformly positive changes rather than shifts to the side.

Introducing the Diamond Insert for the Carbide Base audio equipment footer. The Diamond Insert is an additional vibration isolator inserted into the top of the Carbide Base footer to bring further improvements in low level music detail. Culminating over a year of research and development, it represents the pinnacle of our expertise in passive vibration control for audio.
The new Diamond Insert features large zirconia bearings riding in bearing raceways machined out of solid ceramic – an industry first. The raceways are then thoroughly polished and coated with amorphous diamond using a special Physical Vapor Deposition (PVD) process.
The Diamond Insert vibrating at 10 Hz. The footer achieves near total isolation from 10 Hz and above thanks to a low natural resonance frequency and the PVD Diamond coated ceramic bearing raceways.
The extremely hard bearing raceways resist indentation from the bearings better than other previous designs using softer materials such as steel and titanium. Avoiding raceway indentation defects allows the bearings to better dissipate vibrations via the concept of vibration Transmission Path Evasion.
The result is a further lowering of the already exceptionally low noise floor of the Carbide Base footer.
TwinDamp™ Alloy
The Diamond Insert also incorporates our new TwinDamp™ material based on a manganese-copper twin crystal metal alloy. Manganese-copper alloys have over 10 times the damping capacity of copper. Multiple stages of temperature treatments are performed in-house to further enhance the damping properties of this exotic alloy.
TwinDamp™ is utilized in the top center threaded hole and above each of the ceramic bearing raceways for effective damping of vibrations passing through the footer.
The Evo version standard Carbide Base footer can be upgraded to the Diamond version by purchasing the Diamond Insert. The upgrade is accomplished by unscrewing and replacing only the top center section of the footer. The original Carbide Base footer with the felt top cannot be upgraded to the Diamond version.
Carbide Audio introduces the new Evo update to the Carbide Base audio footer. Far from a simple evolution, every part except for the internal ViscoRing™ was redesigned to further enhance vibration control performance.
Improved coupling better allows low amplitude vibrations to pass into the device to be dissipated as heat. The following changes were made to improve coupling:
Updates to the lower ball bearing isolation stage better allow small horizontal footer movements in response to low amplitude vibrations – a critical component for the isolation of micro vibrations. The following changes to were made to the lower isolation stage:
Our patent pending Progressive Shape Factor technology has further evolved. As the ViscoRing™ bulges under compression, ridges within the housing progressively brace the bulging surfaces more gradually as the load initially increases. This results in better isolation performance when supporting equipment on the lightweight end of the weight range for a given ViscoRing™.
While performance in the critical bass and midrange frequencies is similar, the high frequency performance has improved with the updated Evo version.
Horizontal vibration energy transmitted from a 2-way loudspeaker into a 13.6 kg (30 lbs.) weighted aluminum plate placed on top of the loudspeaker. Measurements were taken with the plate on 4 floor spikes and then with the plate on 4 of the Evo version of the Carbide Base footers. Super Light ViscoRings™ were used. Horizontal acceleration was measured with a ACH-01 sensor, 10 dB gain, using 30 Hz to 10 kHz log swept sine excitation.
