The Metal Box ]

Hi-Def Audio has constructed an outlet box named "The Metal Box". The special features of this box, include:

* Star wiring to each receptacle. (The receptacles aren't simply "chained" together, in series).

Wire & Plug Options

* A 4 conductor 10 gauge cord connected to the outlet box. Two separate 10 AWG copper ground wires are inside the the cable. RFI suppression is accomplished with a "one way" or "unidirectional" cables. This is known as a telescoping or telescopic ground. One of the ground wires is connected to the outlets' grounds (in a star wire fashion), and the other ground is connected to the box and telescoped to the audio equipment(with no connection there). Steel has excellent permeability of magnetic fields- so it is a good choice of materials for audiophile outlet boxes. By connecting a ground to the box, it also drains away RF, and makes for a much SAFER box.

NeoTech NEP-3001/3200

In 1991, UP-OCC had been granted by Professor Dr. Ohno of the Chiba Institute of Technology in Japan to introduce the innovation of Ohno Continuous Casting Process into the Hi-fi industry.

The unidirectional UPOCC, being free from impurity (up to 99.99998% pure copper and silver) has electric resistance and practically no crystal boundaries. Neotech has been producing outstanding cable using "single crystal" UP-OCC Copper, developed by Professor Ohno of the Chiba Institute of Technology in Japan. UP-OCC copper has an average crystal size of 410 feet! Compare this to the average crystal size of Oxygen Free Copper, which is 3/4". UP-OCC copper and silver are considered the ultimate in copper and silver conductor technology today.

Accordingly, it is able to transmit electrical signals faster, and with less distortion than ordinary OFC and silver wires. All of these features make the pure OCC copper and silver the state-of-the art conductor materials for the audiophile cable industry.

At the heart of NeoTechs cable design is the use of UP-OCC copper and silver metallurgy employing the continuous-casting method as developed by Professor Ohno of the Chiba Institute in Japan. The unidirectional UP-OCC, being free from impurity (up to 99.99998% pure copper and silver) has electric resistance and practically no crystal boundaries. The net result is a cable with a signal path free of mechanical (electron collision) and electrical distortion as compared to oxygen free copper (OFC) and silver wires typically used in cable manufacturing. As a Materials Engineer, it easy for me to envision that an electrical signal transmitted through cable free of grain boundaries would sound more precise, focused, smoother, and less distorted, but the proof is in the hearing.

The NeoTech NP-3001 power cord consists of three multi-strand cores (positive, negative, and ground), a silver Mylar foil, drain wire and three spacer rods all housed within a PVC outer jacket. For each multi-strand core, there is a PE central cord that runs along the length of the wire. Concerning the NP-3001 power cord, the silver Mylar foil and drain wires are only connected to ground on the male connector side. Three PE spacer rods are used to absorb mechanical resonance. Both IEC connectors are custom built by NeoTech design using OCC conductors with gold plating. As power cords go, I would classify this one as semi-stiff .

Using UP-OCC copper in the manufacture of audio cables results in a distinct advantage over cables using lower purity multi-crystalline OFC with my reference cables sounding unnatural and constricted in comparison. The effects of using the UP-OCC copper in your system is addictive � the more you add, the more you want to remove the other OFC cables.

The Neotech NEP-3001 utilizes 10 AWG individual conductors for hot, neutral, and ground, as well as an aluminum/mylar shield. The overall outside diameter of NEP-3001 cable is 0 .6".

The NeoTech NEP-3200 power cord uses the same UP-OCC copper but the similarities ends there. This higher gauge cable is multi-stranded with teflon insulation covering each strand and the strands surrounding a central hollow PVC tube that extends along the length of the cable.  9 AWG.  A true reference grade power cord,  with the NeoTech NEP-3200, vocals will take a more natural palatable quality. Improvements will also be heard in areas of image bloom, focus, soundstage width, sense of space and the expression of micro/macro contrasts. A significant jump in resolution and space between instruments will likely be noticed.

This cable, like all of our power cables, is available with the

Oyaide P-079(Direct Gold), and the P-004(Beryllium Copper-Platinum/Palladium plate). We also have the Wattgate, and Marinco line of connectors. Click here.

 ANNOUNCING A NEW STANDARD IN POWER CABLE DESIGN: THE "TUNAMI"

2006 Excellence Award (Japan)
2006 Visual Grand Prix (Japan)

Oyaide Electric with experience gained from a long history of cable design, has developed a reference standard power cable called the "Tunami". The cable is constructed using PCOCC-A wire developed by Furukawa Electric using advanced heat control and extrusion technology. The cable utilizes a 5.5 sq. mm conductor core that is rated up to 30 amps and can take up to 600 volts A/C. This makes it a leader in its class delivering a powerful sound. In addition it has a unique 3 layer shielding system not only to shut out external noise but also to suppress internal noise resulting in a very low noise floor. The combination of advanced and creative technologies delivers the recording artists' every intention along with the delicate atmosphere that surrounds them.

PCOCC-A

This is an ultra pure single crystal copper originally developed by Professor Ohno. It was then further evolved into PCOCC utilizing a single copper grain wire. This design results in an extremely low level of signal disturbance and loss due to the lack of crystalline borders along the signal path.

Oyaide Electric has further refined this process with a highly controlled heating and cooling process and improved furnace management to realize a mirror finish. It is now called PCOCC-A and is the epitome of Japanese craftsmanship.

3-Layer Shielding

It is a fundamental requirement of cable design that they be free from external noise. Oyaide has been a leader in this area with our traditional star-quad structure.

We have gone a step further with the "Tunami" employing a unique three layer shielding system.

The first layer absorbs the disorders of electromagnetic field formation; the second (carbon) layer is used to absorb the random movement of electrons caused by current fluctuations stored in insulating materials and a third copper foil layer with a drain wire to protect from external noise sources. The drain wire is then connected to ground for perfect shielding.

Insulator

It is our philosophy at Oyaide to try every possiblity until we have achieved the optimum harmony among the various materials employed in a design. We tested multiple variations in hardness and density of insulating materials to determine which combinations would yield the greatest resonance control. The result was to employ several grades of high polymer polyolefin in the internal structure for maximum benefit.

We then developed a method for applying the coverings onto the conductors with greater tension to achieve a more uniform and secure fitting.
