7N-PC8100 Legenda


Acrolink has taken the most advanced triple shielding system to achieve a current supply like the flow of water. Considering the reality of no 8NCu conductor, Acrolink re-examined the existing materials such as covering materials, insulation materials, shielding layers, and structural designs, as well as verified new materials that have emerged. For example, they changed the thickness and order of the covering material. They conducted component-level and overall-level prototypes and listened in multiple audio systems. Acrolink's 7NCu is an ultra-high purity material that guarantees purity of 99.99999% or more. Now, they have launched a new product, 7N-PC8100 Leggenda, which surpasses the 8N-PC8100 Performante with almost the same state using new methods and methodologies.

7N D.U.C.C.® (Dia Ultra Crystallized Copper)

D.U.C.C stands for Dia Ultra Crystallized Copper which is specifically developed copper wire for high-end audio cables. D.U.C.C has controlled crystal structure and the minimized transmission loss.

Patent technology and registered trade mark of Mitsubishi Materials LTD.

Noise BEAT® Tape:

A film made by stacking a magnetic foil that achieves high electromagnetic wave absorption performance, which is equally effective in reducing radiated noise and improving resistance to external noise. Developed by NTT Advanced Technology Corporation.

Mainstay technology of ACROLINK - Stress-Free

Stress-free processing of raw materials is another remarkable feature along with the use of 6N raw material, and the mainstay technology of ACROLINK brand products.
Although the raw materials have improved purity, enlarged crystals and extremely stable atomic arrangement external stress cannot be avoided at many stages of processing due to bending, etc. Disorder in the atomic arrangement called a “deformation defect” may occur during the process. The raw material is generally annealed to accelerate crystalline growth to restore the original large crystalline structure during the wire drawing process, but when the finished wire is being wound on reels for distribution or being wired, a problem arises due to some external stresses loaded on wire.

The ACROLINK's stress-free products are the only cables in the world which, through a unique annealing process, have high purity copper characteristics with a crystalline structure that is restored to its original stable crystalline structure through a self-annealing phenomenon, except when the external stress is extremely severe. Transformation of atomic arrangement occurs when the wire heated after the wire drawing process is reduced to only one billionth of that of 4N copper and the number of crystals is also reduced to 1/80 to 1/100. Loading wire with electric current accelerates 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 ultrahigh fidelity.
