The DSS-4.1 is virtually identical to the Furutech DPS-4.1 POWER CABLE, but it omits the safety ground.

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.
