Neotech NEI-3001 G-UP OCC Graphene / NEX-OCC II G-UP OCC

Description - Neotech NEI-3001 G-UP OCC Graphene / NEX-OCC II G-UP OCC

evaluated by listening:

there are not many signal cables that can offer what this one does, the music has a perfect bass foundation just by the fact that there are wires like concrete, the music has punch and really entertains and the music also has the necessary shine, but it doesn't dazzle like many wires where there is silver plated copper! It's a whole different league of music, clarity, liquidity and solidity of display. I highly recommend it for systems that need to be set up, where bass and clarity are needed and where treble is in short supply. All of which this cable has to offer! Highly recommend.... sound is very open, like a real music scene in its concert form. Clarity of musical expression, speed and great natural dynamics. What is important is that the cable plays great from the first moment, no burning in and waiting to hear how it plays! I would say the ideal cable for most equipment! Some might miss the taught ambiance of the music on some tracks. Every track is a full on concert! One of the best sounding power cords I can offer and still for good money! A true high end cable without the aftertaste of a disgusting price.....

Graphene features:

Shielding - Carbon and Graphene
High Frequency (RF) noise from Wi-Fi and satellites is ubiquitous today, damaging audio signals more than ever before. That's why the signal cable uses a sophisticated noise cancellation system. In addition to universally proven wire direction control, a shielding layer consisting of a carbon and graphene resistive network (graphene is an ultra-thin high-tech material) is applied to reduce the effects of RF noise. These technologies from Neotech Cable significantly minimize RF noise, which thus cannot enter active circuits, affect the audio signal and be the cause of transparency losses.

Graphene is a super-thin form of carbon similar in structure to graphite, one of the strongest known materials in the world.1 It is only one atom in height and transparent, and as a result of this de facto 2D structure, it also has some special physical properties. It is made up of a planar network of a single layer of carbon atoms arranged in a hexagonal shape connected by sp² bonds. Graphene also occurs in multiple layers, but according to ISO 80004-13:2017, only materials with a maximum of 10 layers may be referred to as graphene[4].

No other material has been observed to have electrons that behave as if they have no effective mass and move at nearly the speed of light. Scientists hypothesize that graphene could be used in the proof of the so-called Klein paradox. This is because, according to current knowledge, this phenomenon should only occur in very extreme conditions (e.g. around black holes). If this were to be proven, it would open the way to the development of a completely new kind of transistor.

As well as being electrically conductive, graphene is also light-permeable, so it could be used in the manufacture of displays and photovoltaic cells. It could thus replace existing devices made of thin metal oxide layers. In addition, a display made of graphene is stronger than those previously made from tin and indium oxides, of which there is a limited amount.5][6][7]

Due to its semiconductivity and a mesh thickness of only one atom, graphene can be used to make transistors that are theoretically capable of operating up to a frequency of 1 THz. Moreover, they can be assembled into very compact units. Thanks to these properties, graphene is expected to be used in microprocessors and memories in the future[8][9][10].

Technological terms:

UP-OCC - pure single crystal metal structure without typical crystals on the surface, the highest quality level of current development, technological know-how of Neotech Dr. Ohno.

OCC - technologically treated conductor in the form of cold rolling of OFC metal and its thickening reducing up to 80% of the original thickness, further surface polishing of the conductor and treatment in a cryo chamber.

OFC - a drawn conductor that has a long grain structure, i.e. about 50 times better structure for conducting sound than the standard manufacturing process

The concept of flat conductor - as we know, sound propagates through a conductor superficially, and if we want to make those surfaces as many as possible for better transmission of all frequencies, we have to add the number of conductors or increase the circumference of the conductor in the case of a round conductor. This brings with it problems, higher cost of conductors, thicker cable with the need for better shielding. Neotech came up with an elegant flat wire arrangement three years ago. One flat conductor is about 2.80 - 3.24 of a standard 0.80 - 1.20mm thick round conductor.

NEOTECH NEI-3001G - Signal cable copper with graphene G-UPOCC 4 x 0.80mm²

is a power cable containing 3 G-UPOCC composite conductors, a combination of OCC copper and graphene. This new conductor represents a significant advance, both in terms of research and industrial applications. The addition of graphene allows for improved stability of electrical signal transmission at high temperatures while maintaining the exceptional conductivity of OCC copper, allowing performance to remain intact even at high voltages. The conductors have CL3 PVC insulation, preventing any transmission of electrical discharge created by the double mylar/aluminum shielding and braided tinned copper. The whole assembly is enclosed in a robust, flexible PVC jacket.

Sold by the metre, this cable therefore allows you to design a very high quality signal cable, moreover perfectly adapted to conduct high currents for demanding HiFi systems. In addition, the excellent quality of electrical signal transmission that these cables allow makes it possible to offer a very beautiful sound restitution by gaining dynamics.
