Neotech NEP-3002 Graphene / NC-P312-303 Graphene

Description - Neotech NEP-3002 Graphene / NC-P312-303 Graphene

Evaluated by listening:

There are not many power cables that can offer what this one does. The music has a perfect bass foundation simply because the wires are as solid as concrete. The music has drive and is really enjoyable, and it also has the necessary sparkle. It's a completely different league of music, purity, liquidity, and solidity of presentation. I highly recommend it for systems that need to be brought up to speed, where bass, clarity, and a lack of highs are needed. This cable offers all of that! I highly recommend it.... The sound is very open, like a real concert hall. The musical expression is clear, fast, and has great natural dynamics. Importantly, the cable sounds great from the moment you plug it in, no burn-in or waiting to see how it will sound! I would say it's the ideal cable for most systems! Some might miss a certain ambient feel in the musical presentation of some tracks. Every track is a concert at full blast! The cable is available with connectors that are also from the G series treated with graphene. One of the best-sounding power cables I can offer, and for a good price! A true high-end cable without the taste of an exorbitant price. Ideal for 85% of music genres, including pop, rock, metal, older music from the 90s, electronic music, and hi-res recordings! When listening to folk, jazz, blues, and large orchestral pieces, typically serious music, I would use a different type of power cable, such as the Furutech FP-032N or FP-TC31, but otherwise this is a great cable for really good money!

Useful properties of graphene:

Shielding - Carbon and graphene
High-frequency (RF) noise from Wi-Fi and satellites is ubiquitous today and damages the audio signal more than ever before. That's why the signal cable uses a sophisticated noise suppression system. In addition to universally proven conductor direction control, a shielding layer consisting of a carbon and graphene resistance network (graphene is an ultra-thin high-tech material) is also applied to limit the influence of high-frequency noise. These technologies from Neotech Cable significantly minimize RF noise, which cannot enter the active circuits, affect the audio signal, or cause losses in transparency.

Graphene is an ultra-thin form of carbon with a structure similar to graphite, one of the strongest materials known to man. It is only one atom thick and transparent, and due to this de facto 2D structure, it also has some special physical properties. It consists of a flat network of a single layer of carbon atoms arranged in hexagons connected by sp² bonds. Graphene also occurs in multiple layers, but according to ISO 80004-13:2017, only material with a maximum of 10 layers may be designated as graphene.

No other material has yet been observed in which electrons behave as if they have no effective mass and move at nearly the speed of light. Scientists believe that graphene could be used to prove the Klein paradox. According to current knowledge, this phenomenon should only occur under very extreme conditions (e.g., in the vicinity of black holes). If this were proven, it would open the way for the development of a completely new type of transistor.

In addition to electrical conductivity, graphene is also transparent to light, so it can be used in the manufacture of displays and photovoltaic cells. It could thus replace existing devices made of thin layers of metal oxides. A graphene display is also stronger than those currently manufactured from tin and indium oxides, which are also limited in quantity. [5][6][7]

Thanks to its semiconductivity and mesh thickness of just one atom, graphene can be used to manufacture transistors that are theoretically capable of operating at frequencies of up to 1 THz. In addition, they can be assembled into very compact units. Thanks to these properties, graphene is expected to be used in microprocessors and memory in the future. [8][9][10]

Technological terms:

UP-OCC – pure monocrystalline metal structure without typical crystals on the surface, the highest quality currently available, technological know-how of Neotech Dr. Ohno.

OCC – technologically modified conductor produced by cold rolling OFC metal and reducing its thickness by up to 80% of the original thickness, followed by surface polishing of the conductor and treatment in a cryogenic chamber.

OFC – a drawn conductor with a long-grain structure, which is about 50 times better for sound conduction than the standard manufacturing process.

The term flat conductor – as is well known, sound travels along the surface of a conductor, and if we want to maximize the surface area for better transmission of all frequencies, we must either increase the number of conductors or increase the conductor circumference in the case of round conductors. This brings with it problems such as higher conductor prices and thicker cables requiring better shielding. Three years ago, Neotech came up with an elegant solution for flat conductors. One flat conductor is approximately 2.80–3.24 times the thickness of a standard round conductor with a thickness of 0.80–1.20 mm.

NEOTECH NEP-3002G - power cable copper G-UPOCC graphene 3x4.17mm² Ø14mm

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

This cable, sold by the meter, allows you to design high-quality power cables that are perfectly suited to carrying high currents for demanding HiFi systems. In addition, the excellent electrical signal transmission quality of these cables allows for very beautiful sound reproduction with great dynamics.
