AudioQuest NRG-Z3 3-Pole Power Cable Three-Pole, Low-Distortion Power Cable Engineered for Media Streamers, Blu-ray Players, and Cable Boxes: AudioQuest NRG-Z3 Delivers Gains in Dynamics and Clarity, Uses PSC Conductors Specifically designed for video displays, powered loudspeakers, and electronic components , the AudioQuest NRG-Z3 power cable nets remarkably noticeable gains in dynamic, immersive performance over stock types. This three-pole cable uses direction-controlled Perfect-Surface Copper (PSC) conductors in a semi-solid concentric arrangement in which the individual copper strands are packed extremely tight and never change position. The immediate result: significant reductions in strand interaction distortion . In addition, the smooth, pure Perfect-Surface conductors minimize distortion caused by grain boundaries and surface discontinuities that exist in any metal conductor. Finally, NRG-Z3's direction-controlled silver-plated shield conductors efficiently drain radio-frequency noise . You'll see sharper images, hear clearer and more detailed sound, and enjoy dramatic improvements from your music and video content – 100% Music Direct Guaranteed . Distortion-Reducing Construction: Semi-Solid Concentric Perfect-Surface Copper Conductors In a semi-solid concentric arrangement, the conductor strands are packed tightly and never change position within the bundle. This construction significantly reduces strand-interaction distortion. The extremely pure and smooth surface PSC conductors minimize distortion caused by the grain boundaries that exist within any metal conductor. Immerse Yourself in the Moment: Silver-Plated Drain Wires Direction-controlled silver-plated shield conductors efficiently drain RF noise from the line and neutral shields to ground via the third ground pin.
