There used to be a pianist who devoted himself to studio recording to immerse himself in music. On the other hand, there was a conductor who thought that the life of music dwells in live performances. And the pianist had a sound source that could be called the treasure of the music world, and the conductor had a valuable live broadcast sound source. The performer considers the meaning of each note and symbol and fills the inside of the sound. Even if it’s live, once the performance starts, there is only one sound creator there. If you overlook just one note, it will definitely become a weakness later.
–The development of audio cables is exactly the same. If you compromise on one material, you cannot hope for a true link to “music” after all. Made in Japan material production technology is updated daily. Acrolink accurately captures and reflects its evolution, and there is no hesitation in introducing it. Genuine purity 99.99999%, crystal grains are epoch-making large, and stress-free processing only with ultra-high purity Cu and acrolink with uniform direction. The conductor is the highest acrolink balance for both hot and cold = wire diameter 0. 19 wires of 26φ are twisted in the opposite direction under high density and optimum tension while uniformly applying squalane oil, and the hot side is coated with natural color polyethylene without pigment and the cold side is coated with high molecular weight polyolefin (black). .. The synergistic effect of using different materials further improves sound quality. A silk thread and an electromagnetic wave absorbing non-magnetic thread are placed between these two cores to enhance the static electricity removal effect, and the inner sheath is formed of a high molecular weight polyolefin mixed with tungsten + amorphous powder that suppresses unnecessary vibration. Furthermore, a double shield layer is formed on the outside by copper foil tape and UEW + silver-plated annealed copper wire braid. The outermost circumference is finished with UV resistant transparent polyurethane. Of course, both the connector and the material structure are Acrolink original. The RCA terminal inherits the 7N-A2070II. Beryllium copper 50 on the center pin. After double buffing (mirror surface) processing on the surface, silver-plated base x finest thick rhodium-plated finish. Furthermore, the bag nut at the boundary between the cable and the plug is machined from solid duralumin, which has extremely excellent vibration damping characteristics. An ideal RCA plug with better information transmission capability. The XLR terminal uses the highest model among the Acrolink original connectors used in that 8N-A2080 Performante. High-quality direct rhodium-plated high-quality tellurium copper (male) and beryllium copper (female) are used. By combining carbon fiber with a body carved from solid brass, it is a high-precision, high-quality connector unique to Acrolink, which is extremely robust. The quest for acrolinks, such as thorough material selection, architecture design, and original terminal design, has already gone far beyond a quarter of a century, and is a state of “sophistication” that can only be achieved over that time. Even if the name is the same, the purity, hardness, and durability have been improved, and the material has been updated to be more suitable for audio cables to achieve further optimization. A2070 Leggenda is born.

Original stress-free 7NCu : Acrolink ‘s stress-free products use a unique special annealing treatment and high-purity copper properties to restore the tissue to a healthy state by self-annealing unless the external stress is too high. But it’s the only cable. At the time of heat treatment after wire drawing, the atomic arrangement transition is on the order of 1/1 billion compared to ordinary 4N copper, and the number of crystal grains is 1/80 to 1/100. Furthermore, the flow of electric current promotes the aging = self-annealing environment, reduces residual strain, restores the structure soundly, and improves the sound quality.

7N DUCC Cu : Dia Ultra Crystallized Copper is a high-purity copper conductor for audio cables developed by Mitsubishi Cable Industries Ltd., which grows crystal grains to several tens of times larger than general pure copper and aligns the direction of the crystal lattice. It is a material. The larger the crystal grain, the smaller the grain boundary (boundary surface between crystals), which has a great advantage in sound quality, but metal crystals have directionality and it was necessary to align them as well. The direction can be observed by the analysis phenomenon by X-ray irradiation, but by optimizing the manufacturing process such as bus line, wire drawing process, annealing (annealing), “optimal direction for audio signal transmission” is provided. An extremely good wire rod was completed.
