Our Design:

Our multilayer 26-AWG Litz wire is one of our first custom designs, which we develop each year as technology advances.


This design remains one of our highest-regarded all-time bestsellers to this day.

The extensive success of our custom 26-AWG wire design resulted from many years of experimenting with dozens of different samples in numerous configurations.

Our latest multilayer 26AWG Litz version is constructed using the most advanced type-6 Litz geometry in an 8-wire configuration. Each conductor has a thick pure cotton center-core which highly improves damping, durability, and flexibility. This design enables the wire to have ultra-low capacitance and resistance, allowing superior sonic performance with any headphone or IEM. 

Wrapping the cotton center-core is an unprecedented number of ultra-thin silver strands, which maximize electrical flow and conductivity, resulting in peerless sound quality by reducing the number of microscopic tears which occur in the OCC manufacturing process and for a consistent impedance distribution throughout the cable. 

Each strand has a layer of enamel coating which helps eliminate electrical interference and prevent oxidation and coloration. 

Each production batch undergoes a deep cryogenic treatment process, which dramatically helps with the final stages of the forming process and smooths out boundaries on the molecular level, providing yet another step to ensure the cleanest and purest current flow throughout. 

Our TPU insulation utilizes a custom-designed synthetic plastic polymer insulation that rejects the microphonics (skin) effect almost entirely and provides the perfect level of protection, flexibility, and crystal-clear transparency. 

Our Metals:

AC's UP-OCC silver and copper conductors are made from the purest silver and copper (99.9999+ purity) without exception, in the most advanced and up-to-date O.C.C manufacturing process. 
You won't find a more pure O.C.C silver or copper Litz anywhere else on the market. 

Just like any other field, OCC wire technology is constantly developing, and while many cable companies that started 10+ years ago prefer to stick with the same-old technologies and outdated manufacturing processes,

our strategy is entirely different, and while this strategy is far more expensive and time-consuming, AC's goal was from day one to become an industry leader in cable technology; therefore, we will never settle for a lesser product and will continue to push the envelope - Implement the latest technologies in our cables, combine new metals and explore new sounds, and increase the purity of our custom cables. 

Our Custom Splitters and Sliders:

We are constantly expanding our splitter and slider selection and offer dozens of exclusive custom-designed splitters and sliders made of ultra-lightweight aircraft-grade anodized aluminum. 

Our splitters and sliders are fabricated by a state-of-the-art CNC machine for the highest precision and polished using a Jig tool to remove sharp edges and small residues. 

Our Connector options:

We are proud to offer our customers a vast selection of connectors, from brass to pure tellurium copper contacts, from plain black designs to carbon fiber with gold accent designs. We have them all, and we will continue to expand our connector selection with new and exciting options.

UP-OCC TECHNOLOGY (2016 article)

 

The unidirectional UP-OCC has low electric resistance and practically no crystal boundaries. Accordingly, it can transmit electrical signals faster

and with less distortion than ordinary OFC and silver wires. These features make the pure OCC copper and silver the state-of-the-art conductor materials for the audiophile cable industry.

 

WHAT IS UP-OCC?

 

UP-OCC stands for Ultra-Pure, Ohno Continuous Casting.

 

The UP-OCC process for refining copper and silver was developed and patented by Professor Ohno of the Chiba Institute of Technology in Japan.

The license to use this manufacturing process is incredibly popular for the production of wire and cable products for the audio/video industry.

 

In conventional processing, hot molten copper/silver is poured into a cooled mold for extrusion, resulting in multiple, fractionated crystal structures.

 

While the copper/silver may be "pure" in the sense of measuring gas impurities in the copper/silver in comparison to standard copper/silver refining techniques, Oxygen-Free Copper (OFC) has undesirable effects that lead many to use more expensive materials such as silver for their conductive strands.

 

As developed for A/V cable use, the OCC process utilizes a heated mold for casting and extruding. With cooling taking place in a separate process, the result is a larger crystal size and increased purity that approaches the 6N, 99.9998%!

 

In another way, traditional copper/silver has oxygen impurities of 200 to 500 parts per million (PPM), while conventional OFC copper/silver reduces to less than 10 PPM. With the OCC process, the figure is cut in half to less than 5 PPM of oxygen and less than 0.25 PPM of hydrogen (compared to 0.5 PPM for OFC). 

With these results, the OCC process creates "ultra-pure" copper and silver.

 

THE BENEFITS OF UP-OCC 

 

• An accurate unidirectional copper and silver crystal that is free from impurities

as possible to prevent corrosion

• Flexibility and fatigue resistance without impairing conductive characteristics

• Low electrical resistance

• Rapid signal transmission

• Corrosive-resistant

• Non-crystal boundaries
