Black Rhodium Libra 5a Mains power Cable

Black Rhodium announces the launch of the LIBRA mains power cable.

The LIBRA cable has been designed with 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 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. This effect can easily be observed when listening to complex musical signals such as massed choirs and large orchestras. 

LIBRA is designed for use with low current equipment such as CD players, turntables, preamplifiers etc. to deliver the very best sound without the expense of giving the cable a high current carrying capacity. LIBRA is suitable for all equipment that requires less than 5 amps of continuous current.

LIBRA has many of the features of previous Black Rhodium power cables that have made them very popular with users of high quality equipment:


  • The positive and negative cores are connected in opposite directions. Experience shows that when cables are connected this way (and both cables are connected in the same direction) the noise floor between the musical notes lowers. This gives ‘blacker’ silences in the interval between musical notes and enhances reproduction of the musical edges and natural decays in music.
  • Silicone rubber insulation is used because its low dielectric loss ensures extremely low distortion due to dielectric absorption effects in which sound energy is absorbed in the insulation and released at a later interval of time to create highly audible time-smearing distortion. • LIBRA and CRATOS are both very flexible and as a result are much more convenient to use than cables that are less flexible.


  • Conductors 16 x 0.2mm tinned copper
  • Conductor size 0.5 sq mm - 20 gauge
  • Insulation: Silicone rubber type GPC
  • Inner insulation thickness 1.2mm
  • Cable outer diameter 9.1mm
  • Current Rating: 5A
