The Alpha 11 OCC Custom Power Cable by Douglas Connection is made using Furutech FP-Alpha 3, 11 AWG OCC (Ohno Continuous Cast) Copper power cable, and your choice of plug and IEC connectors.  These custom made cables will bring significant improvement to both performance and sound quality in a very dramatic and noticeable way.  The Douglas Connection Alpha 11 is a flexible AC cord made specifically for the high power demands of any amplifier or receiver, or to deliver unhampered AC power to the entire system when used with a power distribution/line conditioner.

About the Furutech FP-Alpha 3 OCC cable:

The OCC process for refining copper was developed and patented by Professor Ohno of the Chiba Institute of Technology in Japan.  The OCC process utilizes a heated mold for casting and extruding, with cooling taking place in a separate process. The result is a larger crystal size and increased purity that approaches the 6N, 99.9998%! Looking at it another way, traditional copper has oxygen impurities of 200 to 500 parts per million (PPM), while traditional OFC copper reduces that to less than 10 PPM. With the OCC process, the figure is cut in half to less than 5 PPM of oxygen, and less than 0.25 PPM of hydrogen (compared to 0.5 PPM for OFC). With these results, the OCC process creates “ultra-pure” copper, and thus the acronym for the copper material is more properly known as “UP-OCC”, for Ultra-Pure, Ohno Continuous Casting. The benefits you will realize from the UP-OCC material used in our Alpha line of power cables are: A true unidirectional copper crystal that is as free from impurities as possible to prevent corrosion.  Flexibility and fatigue resistance without impairing conductive characteristics.  Low electrical resistance, and Rapid signal transmission.

About the Furutech connectors we offer for our Alpha 11 Power Cable:

We searched, and tried several different connectors to use with this power cable.  Some were less expensive, and some were more expensive.  What we found through our research was that three series of the Furutech connectors gave us the absolute best performance.  When only the best will do, select the Furutech FI-50 NCF and FI-50M NCF, or FI-52 NCF and FI-52M NCF Rhodium plated pure copper IEC and Power plug connectors (Select the FI-52 NCF series for 20 amp applications).  The engineering, look and feel of these connectors is only surpassed by the outstanding performance we found when using them.  The second choice we recommend is the Furutech FI-50 and FI-52 Non NCF connectors.  The third choice of connectors for this cable are the Furutech FI-28 series Rhodium Plated Pure Copper IEC and Power Plug.  These connectors are the best bang for the buck we offer for these cables. The FI-28 series connectors offer close to the same performance as the FI-50 connectors, but at a lower price point.

About the Furutech FI-50 (R) and FI-50M (R) connectors: Furutech’s Pure Transmission FI-50 Piezo Ceramic series connector bodies and housings feature several breakthrough construction techniques. A multilayer nonmagnetic stainless steel and carbon fiber shell incorporates a special damping and insulating acetal copolymer. The body of the connectors combine two “active” materials: Nano-sized ceramic particles and powdered carbon. Nylon and fiberglass are incorporated as well forming an extremely effective, well damped, mechanically and electrically nonresonant connector body. Furutech FI-50 and FI-50M Rhodium Plated Power Connector Specifications: ・α (Alpha) Pure Copper Rhodium plated conductor ・Earth (Ground) Jumper System (US Patent No.: 6,669,491 ) ・Nylon/fiberglass body incorporating nano sized ceramic particles for absorption of vibration resonance. ・Multi layered nonmagnetic stainless steel and carbon fiber housing and incorporating acetal copolymer. ・The best of damping and insulation materials for improvements in frequency extension and tonal quality. ・Specified for cable diameters from 6mm to 20mm ・Dimensions: FI-50 Body length 44mm x 40.5mm diameter x 80.3mm overall length FI 50M Body length 40.0mm x 40.5mm diameter x 76.2mm overall length ・Metal cable clamp for improved grip and reduction of mechanically and electrically induced distortion.

All metal parts on every product Furutech offers are treated with the Two-Stage Cryogenic and Demagnetization (a) Alpha Process.

Using cutting-edge technology and materials, Furutech developed a low-temperature two-stage process that significantly improves every facet of audio and video performance. The treatment begins during the manufacturing process with a deep, conditioning cryogenic freeze of all metal parts. Using high-end refrigerants — liquid N2 or He — Furutech achieves temperatures of between -196 to -250C. The treated parts actually change their molecular structure at these extremes of temperature relieving internal stress. The molecules bond together more tightly and the overall structure becomes more stable. This improves electrical conductivity, power and signal transfer.

Step two in the Alpha Process exposes these same parts to the patented Ring Demagnetization treatment. Ordinary high power magnets used for this purpose often increase magnetization effects; they leave some areas more magnetized than others. Just like a CD spinning over a fixed magnet; when the CD stops the area above the magnet is still exposed to the magnetic field causing audible effects. This patented process uses controlled attenuation to completely eliminate magnetization for immediately more vivid and colorful improvements. Ring Demagnetization further enhances conductivity of all treated materials. The patent holder for this treatment is Sekiguchi Machine Sale Co., Ltd. in Japan; Furutech are licensed users of the technology.

ALL metallic parts used in Furutech products go through the Alpha Process treatment to keep all connectors, conductors, and metal parts in a perfect stress-free, stable and highly conductive state.

The Final Result:  The 2-Step Alpha Cryogenic and Demagnetizing Process works in tandem with other design-in features to create the most optimized AC power transfer possible. Furutech’s total awareness and devotion to detail results in a greater sense of power, dynamics, and resolution, with cleaner, blacker backgrounds and a larger, more stable soundstage, vivid tonal colors and deeper extension at both ends of the frequency range.
