Both cables have been designed for low ‘Transient Phase Distortion’ by increasing the thickness of the inner insulation to 1.2mm.
“The benefit of thicker insulation is that when two electrical conductors carry an electrical current, the magnetic field produced by the current in one conductor affects the resistance of the other conductor. This is known as the ‘Proximity Effect’. Because the loudspeaker load is reactive, the current and voltage in the speaker cable are not in phase and the modulation effect produces a ‘Transient Phase Distortion’ signal that distorts sound quality. By moving the conductors of LIBRA and CRATOS 2.4mm from each other, the magnetic field (which reduces inversely proportionally to the distance) on the other cable is lowered and the ‘Transient Phase Distortion’ is less audible.”
Libra is suitable for all equipment that requires less than 5 amps of continuous current whilst Cratos is designed for high power amplifiers and power distribution systems and has a continuous current capacity of 15 amps.
