The Reference SPK Red cable is a perfect combination of OFC (Oxygen-free copper) and HiFC (High performance pure copper) conductors. These two copper conductor materials are combined to create a warm, dynamic sound with high resolution.

This cable is ideal for a listener who prefers two single cables for his bi-amping set-up. The advantage of this set-up is that the shield can be connected to each amp and therefore doesn't  mix up the ground potentials on the two separated amps.
