We are thrilled to introduce the most technologically advanced headphone cable on the market: 
Arctic Cables' Ultra-Pure 7N Silver O.C.C /w Pure Palladium Plating.

We've been testing, comparing, and experimenting behind the scenes for over four months now, trying different custom design wire samples, with only one purpose in mind: 

We wanted to create the next-generation silver headphone cable that would outperform all of the high-end silver cables we've heard to date, and by a substantial margin. Only then, we could justify the significant price difference from our Signum+ series.

Since we spared no expense on our silver Signum cable, we knew that the only way to achieve that would be to implement a new kind of metal with our ultimate ultra-pure silver cable. 

Some of the samples we've tried sounded great, but we considered them more like a sidegrade when each provided slightly different sonic characteristics. It wasn't the result we were looking for.

We then decided to try a slightly different approach, and we've changed the wire construction that we use on the Signum wire; with platting the silver wire with a thick layer of palladium, we then finally hit the jackpot.

We've tested the cable using many different headphones; Focal Utopia, Hifiman HE1000V2, Meze Empyrean, Sennheiser HD800, Sony Z1R, Fostex TH-900, Beyerdynamic T1 2nd gen, and Audeze LCD-4z. 

Right off the bat, the level of transparency and clarity was like never before. It was as if the cable was no longer a part of the chain. Each of the headphones seemed to scale-up to their absolute maximum potential. The cable could easily keep up during the busiest passages while pinpointing every instrument placement in the recording with a solid black background.

Bass texture, resolution, and extension were the by far the best we've heard with these headphones that we know so well, soundstage width and depth were increased and had a sense of an enormous atmospheric 3d sound while instruments were still spot-on accurate. Vocals sounded organic and crisp, and the highs are were well extended and extremely detailed without sounding harsh.

The only downside was the cost; since palladium is about 100 times more expensive than silver, and currently even more costly than gold, we had to adjust the price accordingly. Still, just as the Signum series, our profit margin on these complex cables is still significantly lower than average.

Still, we know that spending that much without experiencing first-hand this experience would be difficult. Even though every cable is custom-made, we offer a 30-day trial period. This way, you could sit comfortably, without any pressure, after giving the cable some additional burn-in time and test your new palladium cable with your favorite headphone.

If you're unhappy with your purchase for any reason, you can send the cable back and receive a full refund* without any restocking fee.

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.


All of these features make the pure OCC copper and silver the state-of-the art conductor materials for the audiophile cable industry.




• A true unidirectional copper crystal that is as 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



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


The UP-OCC process for refining copper 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 is poured into a cooled mold for extrusion, resulting in multiple, fractionated crystal structure.


While the copper may be "pure" in the sense of measuring gas impurities in the copper in comparison to standard copper 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%!


Looking at it another way, traditional copper has oxygen impurities of 200 to 500 parts per million (PPM), while traditional OFC copper reduces that
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.
