Using the same technology as the SPK-400 cable, this "little brother" only has two wires of 2.9mm.
Besides the obvious differences, like lower price and smaller diameter, this cable is ideal for the less demanding listener or the high demanding listener that prefers two single cable for his bi-amping setup.
The advantage of this setup is that the shield can be connected to each amp and therefore doesn't mix up the ground potentials of the two separated amps.
The Ortofon Reference SPK-200 Speaker cables deliver dynamic, high resolution, clean and clear sparkling sound in a wide rage of frequencies with no compromise.
