Think power cables don't make a difference? Think again. The Source AC Power Cable is a remarkable upgrade to the power supply of any amplifier or audio component.Solid IGL copper conductors replace the only stranded conductors in the power delivery system.Hot and neutral conductors are composed of four isolated cores each in a helical array around the earth conductor.High-purity proprietary IGL copper conductors for distortion-free midrange and high frequencies.Solid-core conductors eliminate the negative effects of strand interaction on the AC signal.100% shielding blocks noise and bleeds to ground.
