QED Performance Audio Cable (Graphite) From QED's multi-award-winning Performance range, this cable benefits from common-mode noise reduction due to the signal and return conductors being twisted together, as well as an electrostatic screen at the source end to protect from external high voltage noise signals. 24K gold-plated plugs provide low resistance and immunity from oxidization, allowing you to enjoy the clarity of sound that QED always provide for longer! What QED say The multi-award winning Performance range presents the Performance Audio analogue interconnect. Performance Audio utilises design concepts from the high end Reference range to optimise audio performance when connecting your CD player, DAC or Tuner to your amplifier or receiver. These include quasi-balanced geometry, low capacitance dielectric materials and 24k gold plated RCA plugs. All QED cables are covered by a lifetime guarantee. 99.999% Oxygen Free Copper Conductors Provide a low resistance pathway for the audio signal Loew Density Polyethylene Dielectric because of its low dielectric constant this material has been used to cut down on the amount of audio signal energy lost due to cable capacitance Ergonomically Sculptered Zinc Plated Alloy Barrel Provides ease of installation and a stunning finish Quasi-Balanced Geometry Signal and return conductors are twisted together to give a level of common mode noise rejection above that of conventional unbalanced cables Electrostatic Screen Provides immunity from external high voltage noise signals. Only connected at the source equipment end hence the directionality arrows on the cable jacket. 24K Gold Plated Phono Plugs Because gold does not tarnish it provides a lasting low resistance contact
