Base Price is for one 6′ cable with out connectors. For a pair select a quantity of 2.  Other lengths are available.  From the drop down menus, please select the cable length you need, and choose connectors for amp end, and speaker end.  We only offer the very best connectors on our Reference Cables, the Furutech CF-201 NCF R Spades and Furutech CF-202 NCF R Bananas, Furutech CF-201 R Spades or the Furutech CF-202 R Bananas, or the Furutech FT-211 Spades and Furutech FT-212 Bananas.  You will also need to select the free end length you require.  Free end length is the distance between where the individual conductors exit the main cable to the connectors.  
Please enter the number of cables you need.

Douglas Connection Alpha Reference 11AWG OCC/DUCC Speaker Cables are totally assembled by hand right here in the USA, by a small family business.  When making your Cables we use setscrews to affix the bare wire inside the connector, which makes far superior surface contact.  No solder is used in the construction of these cables.

The sleeving that is on the cable from the factory is shown in the roll photo above.  We can be removed and replaced with black sleeving as in the photo above if you wish.  Please specify that you want us to change to black sleeving in the order comments. 

Alpha OCC-DUCC Speaker Bulk Cable DSS-4.1 is treated with the a (Alpha) Demagnetizing and Super Cryogenic process

Furutech’s α (Alpha) OCC‐DUCC is one of a select few of conductors that Furutech engineers have found to excel in sound reproduction. α (Alpha) OCC –DUCC is constructed using a combination of DUCC Ultra Crystallized High Purity Copper and Furutech’s world famous Pure Transmission α (Alpha)-OCC.

Furutech DUCC Ultra Crystallized High Purity Copper — supplied and regulated with strict quality control by Mitsubishi Materials Industries — is one of the best conductors Furutech engineers have found for signal transmission. (MMI is the leading manufacturer of the highest-purity oxygen-free copper in the world) Mitsubishi process this extremely pure oxygen-free copper with new technology that optimally aligns the crystals while reducing the number of crystal-grain boundaries resulting in a tremendously efficient conductor. Straight OCC’s benefits are its larger “fibrous” crystals in which one dimension is longer than the other two so as to create as few crystal junctions as possible. Thus, OCC’s sensitivity to directionality; one path exhibits the least resistance. Furutech’s world famous Pure Transmission α-OCC is the result of further processing with the Alpha Super Cryogenic and Demagnetizing treatment. However, DUCC purity goes a significant step further. Mitsubishi Materials designed the new conductor to optimally align the copper crystal grain structure in addition to reducing crystal grain boundaries. As a result, DUCC is less sensitive to directionality than OCC.

What you will hear when you choose our Alpha Reference 11AWG OCC/DUCC Speaker Cables:

The sonic signature is one of warmth, smoothness, and energy, with an ultra-low noise floor that allows subtle sonic nuances to emerge from an ink black background. Low level details are reproduced with great expressiveness and an absence of grain.
Sonic details sound natural and organic. Our Reference Speaker Cable has an open, clean and resolved sonic image that is both uncannily detailed and VERY revealing.
Tonal breadth is exceptional,
Trebles are crystalline and extremely detailed, but without becoming overblown or bright. These cables also keep away from the clinical sound that can suck the joy out of listening.
The midrange is open and revealing, bringing a strong sense of clarity and definition to the music.
These cables really open up the music, bringing not only detail, but also dimension and presence to the listening experience.
The Alpha Reference Speaker Cables will expand the perceived soundstage, spreading the musical information wide and deep, without comprimising the cohesion and intent of the music.

REVIEW of the DSS 4.1 base cable.
by Douglas Brown
“Minutes after installing the DSS-4.1 speaker cables into my main 2-channel tube rig, the improvement in sonics was so clear that I could literally hear it in other parts of my home. Audio critics love listening to walk through three- dimensional stereo sound in the same way that a mosquito enjoys sucking blood from a diabetic’s ankle. It’s something we can’t resist. The increase in sound quality was so immediate and dramatic that it forced me to return to my listening room.
The DSS-4.1’s sonic signature is one of warmth, smoothness, and energy. These SCs have an ultra-low noise floor that allows subtle sonic nuances to emerge from an ink black background. Sonic details sounded natural and organic. Much like a mile wide diameter oceanic sinkhole in Belize, the profound depth and transparency of the sound let me dive deep into recordings of all genres of music.
Furutech DSS 4.1 SCs recreated the tone and timbre of instruments with a palpable *feel* that created one of the most vivid, lifelike, and expansive soundstages that I’ve ever heard — at any asking price. This ability to recreate realism from recorded music is what every audiophile longs to hear. Instead of chasing the sonic dragon in a Tokyo taxi during rush hour traffic, I felt like I was finally flying on the fabled beast’s back.
The DSS-4.1 never altered the base sonic characteristics of any of the stereo systems I used to test them.”

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 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 and so 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.

The Final Result The 2-Step Alpha Cryogenic and Demagnetizing Process works in tandem with other design-in features to create the most optimized power and signal 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.
