The Acrolink Approach
Leading the world in industrial high technology.
True Purity
Various manufacturers claim to produce ultra high purity, 6N (99.99997%) copper; however, different refining processes yield materials that vary greatly in both the composition of impurities and crystalline structure.
Most of the "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 in the accompanying table 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!
Stress-Free
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 as well as reducing the number of crystals: No matter how often the cable is bent or impacted, it will always return to its original relaxed state (uniform crystalline structure). Transformation of the atomic arrangement occurs when the wire is heated after the wire drawing process. The number of crystals is reduced by a factor of 80 to 100. Loading the wire with electric current accelerates the aging or self-annealing function, and reduces residual deformation to restore the original stable crystalline structure, making the wire able to transmit wide-range frequencies with ultra-high fidelity.
Dielectric Material
A rare new polymer of polyolefin, presently the best material available, has been chosen for the insulator for its extremely low dielectric constant.
This new material was selected after conducting a large number of tests that involved cutting and listening. The resin is an excellent material of the highest grade which has a low dielectric constant that is 1/4 of that of conventional PVC. Qualities that were given highest priority in choosing to adopt this material were: balance of energy throughout all bands, reproduction capabilities of phase elements, high level, high speed and high response reproduction, and natural sound quality. Undesired vibration can be eliminated by combining two different types of the material. The result is the realization of a dramatic improvement of sound, an experience unlike anything that has been realized thus far.
Resonance Absorption
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.
