C2 PCOCC Premium XLR

Our C2 cables utilize PCOCC copper, the finest quality copper you can buy due to its innovative casting process. This also makes it some of the most expensive copper as well.

A little about PCOCC copper

 In general terms, the purer the copper, the better the signal and sound. OFC copper, as its name implies, is copper with the oxygen removed (in actuality, it is not 100% removed, but greatly reduced). OFC copper can vary in quality due to differences in processing, but overall, reducing the oxygen content slows the formation of copper oxides in the conductor, which can disrupt the copper’s physical structure and ultimately degrade sound quality. OFC copper typically has 50ppm (parts per million) of oxygen. Traditionally, drawn OFC copper also has a discontinuities in the copper called grains. The signal can be adversely affected by traversing these grains, further degrading sound quality. Standard copper has about 1500 grains per foot.

The highest-quality technique for drawing copper is OCC. OCC copper has one grain in about 700 feet. The audio signal travels through a continuous conductor instead of traversing grain boundaries. OCC copper is found in many of the highest-quality (and priced) cables due to its purity.*

The difference in sound quality between PCOCC copper and OFC copper can be quite dramatic. Resolution, background noise and extension are all superior with OCC copper. Overall, you can expect to be that much more immersed and involved with the music than with standard cables.
