Various manufacturers claim to produce ultra high purity, 7N (99.99999%) copper; however, different refining processes yield materials that vary greatly in both the composition of impurities, and crystalline structure.
Most "so called" 6N and 7N materials are not measured comprehensively. Glow Discharge Mass Spectrometry - an extremely powerful tool for performing ultra-trace elemental analysis - has been applied to Acrolink's 6N pure copper. The results demonstrate that Acrolink has achieved an unrivalled standard of purity.
The Effect of Impurities
Minute impurities create variations in impedance, inhibiting the ability of a cable to achieve extended frequency response. Responsible for meeting the needs of leading edge computer and aerospace technology, Acrolink has developed a multi-stage process that removes each impurity individually. Applying this to audio they have been able to achieve flat frequency response to 18 GHz in their Mexcel series!
After the cable core is formed, the Acrolink Stress-Free process is applied in a clean, oxygen free environment. This imparts permanent self-annealing properties: No matter how often the cable is bent or impacted, it will always return to its original relaxed state (uniform crystalline structure).
A new polymer polyolefin, presently the best material available, has been chosen for the insulator for its extremely low dielectric constant (1/3 of polypropylene and 1/4 of PVC).
Proper absorption of resonance is one of the key factors in determining final sound quality. Acrolink has focused on this issue for many years and developed tremendous expertise. Materials are carefully selected for each individual design in order to achieve perfectly balanced and effective absorption.
