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: lifetime

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.

Greetings Nathan. Thank you for your question. Power cables should not have an in wall rating. We do not recommend them going in any wall or ceiling. Check with your local building inspectors before installing a power cable in your wall.

I'm thinking of replacing the flimsy 2 prong, but polarized power cables on my old Sony CD exchanger and an old Infinity subwoofer. Both of these components have the power cord directly soldered; no IEC type connecters. Would it be a simple matter of removing the end of this new cord and soldering the wire in the exact manner of the old cord? I'd go with a 3 prong cord, but I've read a lot of conflicting opinions on where to connect the ground wire.

We have not tested and do not recommend cutting a permanently attached power cord to replace it.

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
