Furutech DSS-4.1 - 11AWG Alpha OCC-DUCC Reference Speaker Cable

Combining some of the best materials know to science with their legendary R&D, Furutech's DSS4.1 Speaker Cable is their top-tier reference speaker cable. The Furutech DSS-4.1 combines the finest materials and expert craftsmanship for an unrivaled listening experience. Count on the technology of Furutech to deliver unparalleled audio quality.

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 makes the Furutech DSS-4.1 Speaker Cable especially appealing (aside from its sonic performance), is DIY'ers now have access to a State-of-the-Art bulk speaker cable that can ALSO have the finished appearance of >$10k commercially finished cables, when you also utilize the Furutech Speaker Cable Splitters (sold separately).

Furutech's DUCC Ultra Crystallized High Purity Copper is supplied and regulated with strict quality control by Mitsubishi Materials Industries. MMI is a leading manufacturer of the highest-purity oxygen-free copper in the world. Mitsubishi's process uses newly developed technology that optimally aligns the crystals while reducing the number of crystal-grain boundaries.

The DSS 4.1 Speaker Cable comes included with a textile sheath/covering which is soft to the touch, and very attractive. This cable has a shield, and is designed not to need connection at either end, per Furutech's recommendation. Flexibility is exceptional, and much better than many speaker cables of this AWG and/or diameter.

The Furutech DSS Cable Splitters (sold separately) for the DSS-4.1 are packaged as a set of 4, for one pair of completed cables and make a great 'breakout boot' for the + and - pigtails.
