The 7N-S8500 Leggenda incorporates high purity “Stressfree” copper conductors. The material purity of conductors used for critical areas is 7N (99.99999%) copper. This high purity material was originally developed for the semiconductor industry which requires an extremely high level of quality certification, and guarantees 7N purity with less-than-0.01 ppm (parts per million), of metallic impurities. This quality level is maintained by using ‘GD-Ms’ high precision material analysis technology. The high purity copper wire uses special “Stressfree” annealing technology to minimize distortion of the crystalline structure of the copper. This new power cord also features extra-large crystalline structure conductor technology, “D.U.C.C.” (Dia Ultra Crystallized Copper) in order to farther optimize the high purity and conductivity of the power path.

The stabilizer is made of aerospace aluminum alloy with vibration attenuation properties, and the outer shell is made of carbon fiber to achieve extremely high vibration damping properties. Effectively reduce vibrations generated by the working cap and unwanted external vibrations. As the flagship model, it is the ideal connection system of the highest quality ever.

In order to cope with the environment where digital noise is gradually increasing, the air pipe design born in Acrolink's "Development Museum" will come in handy. When audio signals are transmitted from the audio source device through the speaker cable, they may be subject to electromagnetic interference from the surrounding environment or other electrical equipment. These interfering signals may cause sound quality distortion, noise, or other undesirable effects. The setting of air ducts can provide additional shielding and isolation, reducing the impact of external interference on the audio signal. This insulation design has good isolation properties and can reduce the influence of external electromagnetic fields. At the same time, the air tube can also reduce signal loss and improve signal transmission efficiency.
