But the fact that the new SC-DUAL BLUE is a hit will not surprise anyone who ever had the pleasure of listening to its big brother, the SC-QUADRA BLUE. The SC-DUAL BLUE is not a slimmed down version of the SC-QUADRA BLUE, but a speaker cable with a special pitch which has been optimized for a 2-pole connectivity. This connection is recommended for stereo systems where the speaker terminals are bridged or have no bi-wiring/bi-amping connections. The SC-DUAL BLUE impresses by its smart construction, the timeless and modern design and a straight-in-your-face, impulsive and natural reproduction. This cable brings out the best your hi-fi system has to offer.
