ACROLINK 7N-PC4030 Purosangue CB

Why is it that the cello and double bass are the first to play the Ninth Ode to Joy?
What is the outline and backbone of the content entrusted to it?...And then there is the climax.
The birth of a favorite power cable that is like a thoroughbred that runs as you please.

Once upon a time, when almost all cable coverings were made of polyvinyl chloride, there was a time when people who made their own audio products were whispering that cotton-covered cables had better sound."Nature" has created a variety of substances and materials, from inorganic and organic, genes and viruses, to giant life forms, through a tremendous amount of experimentation and time.The “rediscovery” of materials is an extremely interesting scientific field.In the first place, the world's first ultra-high purity copper, developed by Acrolink when it was formerly known as Acrotech, is itself the ultimate natural material.The latest model in the 7N-PC4030 series uses silk material for the intervening layer.It's a new hardness and softness.The visibility of left/right, top/bottom, depth, and spatial information is deep, the resolution is precise, the clearness of the atmosphere, and the ability to describe the substance and positional relationships of musical instruments.Above all, it is an evolution that allows even the emotions to be conveyed more deeply.The name has also been changed to a new sound, Thoroughbred = Purosangue (Italian).A new era of audio cables begins once again with the Acrolink Power Cable.

Features

[Cable]

Of the three core wires, two of the power wires are Acrolink 7N Cu D.U.C.C. Stressfree 0.37mm x 50 wires (5.4sq), and the ground wire uses high-grade 4N5 super soft copper wire with the same configuration as the power wire, a concept kept from the previous work 7N-PC4030 Leggenda.These three conductors are coated with Acrolink's unique high-quality insulating polyolefin resin and have a core wire with an outer diameter of 4.7 mm, and an electromagnetic wave absorbing non-magnetic thread is placed in the center of the core wire to form the conductor.Silk is placed in the intervening layer, and paper tape, copper foil tape, inner sheath of polyolefin resin containing tungsten and amorphous, and outer sheath of polyolefin are densely layered to create a perfect structure.With the sense of openness brought about by the natural material of natural silk, the overwhelming vibration damping effect, and our unique know-how in reducing noise from the outside, we delicately and powerfully support the high-quality sound inherent in amplifiers and other audio equipment at a high level.

[Original stress-free 7N Cu]

Acrolink's stress-free products are the only cables in the world that use a unique special annealing process and the characteristics of high-purity copper to restore the structure to a healthy state through self-annealing unless there is too much external stress.

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 current promotes an aging (self-annealing) environment, reducing residual distortion and restoring the tissue to a healthy state, resulting in higher sound quality.

【D.U.C.C. 7N Cu】

Dia Ultra Crystallized Copper is a high-purity copper conductor for audio cables developed by Mitsubishi Cable Industries, Ltd. It is a material whose crystal grains have grown to several tens of times larger than that of general pure copper, and whose crystal lattice orientation is aligned.

The larger the crystal grains, the fewer grain boundaries (interfaces between crystals), which has a great advantage in terms of sound quality, but metal crystals have directionality, which also needs to be aligned.

Although its directionality can be observed through analytical phenomena caused by X-ray irradiation, by optimizing manufacturing processes such as the bus bar, wire drawing process, and annealing, we were able to create an extremely superior wire material with ``optimum directionality for transmitting audio signals.''
