ACROLINK 7N-S1010 Purosangue

The sound changes depending on the cable...This fact, which has become "common knowledge around the world," was established in 1989 with the debut of Acrolink (formerly known as Acrotech) 6N-S1010.At a time when 3N to 4N was common sense, we achieved a purity level 100 times higher.Since then, the S1010 series has grown to the present day under the flat spirit of seeking the best (=Acro) technology and materials (=Tech) in every field and incorporating them without any particularity (=Link).It is a long-selling model that has already been shipped over 400,000 km and has traveled around the earth 10 times, and has become the ``prototype of that era'' for audiophiles around the world.Dynamic and detailed signals are transmitted more clearly, the direct sound of instruments and vocals are reproduced with a strong presence, the sense of spread to the left and right, the sense of depth, the indirect sound that depicts the scale in the height direction of the sound field, the level attenuation of the reverberation component disappears without sudden interruptions, and the whole tone disappears, creating a more sophisticated sound world.The new name is Purosangue (Italian), which means thoroughbred sound.This is the birth of "orthodoxy".

The signal conductor uses Acrolink 7N Cu D.U.C.C. Stressfree 0.37mm x 18 wires inherited from the 7N-S1010 Leggenda.The conductor is made of a core wire with an outer diameter of 3.3 mm, which is covered with Acrolink's unique high-quality insulating polyolefin resin, and is twisted together with electromagnetic wave absorbing non-magnetic thread to form the conductor.The intervening layer is made of the natural material silk, and it has a perfect structure that is densely layered with paper tape, copper foil tape, an inner sheath of polyolefin resin containing tungsten and amorphous, and an outer sheath of polyolefin resin.Natural, open feeling.New vibration damping effect and measures against external noise contamination.Using traditional know-how, the amplifier's output is transmitted to the speakers in the cleanest possible way.

Features

[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.''
