About the AudioQuest NRG-Z2
A well-engineered power cable really can make a difference
A well-engineered power cable really can make a difference
The AC power that feeds your gear is the foundation of your system's audio and video performance. Even if you've plugged your components into a power conditioner to clean up the current coming out of your wall, a flimsy stock power cord can act as an antenna for airborne interference that subtly degrades high-resolution audio and video signals.
I was an aftermarket power cord skeptic until I tried one on my high-performance DAC about 15 years ago. The sonic improvement was undeniable.
Advanced materials and construction for lower distortion
AudioQuest's NRG-Z2 uses solid conductors made of high-purity Perfect-Surface Copper+. Solid conductors eliminate interaction between wire strands, which is a major source of distortion in an AC power cable. AQ's Semi-Solid Concentric conductor arrangement packs strands very tightly so that they never change position within the bundle, which significantly reduces distortion.
Make sure it fits your component
The NRG-Z2 works with most components that have a detachable, two-pole "C7" power cord. That includes some CD players and Blu-ray players, most cable and satellite set-top boxes, and all PlayStation® and Xbox™ game consoles.
Product highlights:
- 3-prong connector for wall outlet, 2-pole "C7" connector for component
- direction-controlled Perfect-Surface Copper+ conductors
- Semi-Solid Concentric conductor arrangement reduces strand interaction distortion
- direction-controlled Silver-Plated shield conductors efficiently drain RF noise from the line and neutral shields to ground via the third "ground" pin
- low DC resistance and zero characteristic impedance help deliver uncompressed transients on demand
- maximum current capacity: 15 amps
- textile braid cable cover
- warranty: 5 years
- MFR # NRGZ2US02
What's in the box:
- 6.5' AC power cable (with C7-2 pole connector on one end and a 3-prong AC plug on other end)

Features
NRG-Y2 Series AC Power Cable: The AudioQuest NRG-Y2 AC power cable uses direction-controlled Long-Grain-Copper (LGC) strands in a Semi-Solid Concentric conductor arrangement in which strands are packed more tightly and never change position within the bundle. This construction significantly reduces strand interaction distortion. The greater purity and less complicated grain structure within LGC copper further reduces distortion. In addition, the NRG-Y2 power cable's direction-controlled Silver-Plated shield conductors efficiently drain RF noise from the line and neutral shields to ground via the third “ground” pin.
Semi-Solid Concentric Packed Long-Grain Copper (LGC) Conductors: In a conventional multi-strand cable, distortion caused by electrical and magnetic strand interaction is compounded as each strand changes position within the bundle. In an AQ Semi-Solid Concentric Packed cable, strands within the bundle maintain their fixed relationships, significantly reducing distortion. Long-Grain Copper (LGC) allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance.
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. The net result is powerful, dynamic, and immersive.
Zero Characteristic Impedance: While many AC power cables feature low DC resistance in order to accommodate the demand for high current, a cable's characteristic impedance is also crucial for optimal performance. Unlike most AC cables that constrict or compress an audio-provoked transient, AudioQuest AC cables combine low DC resistance and zero (no) characteristic impedance in order to deliver uncompressed transients on demand.
Connectors: The AudioQuest NRG-Y2 AC power cable features a C7-2 pole connector on one end to plug into your audio/video electronic component and a 3-prong North American AC connector on other end to plug into your AC wall outlet, power conditioner, or surge protector.
Available Lengths: The AudioQuest NRG-Y2 Series power cable is available in 3.25', 6.5', and 10' lengths.

Excellent especially the slim connectors. Beware that AQ mixed the KEF the with the older connectors if you have Sonos or source devices that can only fit the slim C7 end
