Hear Firmer Bass, Smoother Highs, and Enhanced Detail: High-End Power Cable Features PSC+ and PSC Conductors for Stellar Purity What will an optimally constructed, performance-proven power cable such as the AudioQuest NRG-4 do for you?

When you bring clean, high-current power to your system, you get rewarded with more controlled bass, a smoother top end, and improved microdetail retrieval. And that's exactly what NRG-4 does.

It only takes minutes to hear the dramatic difference NRG-4 – equipped with Solid Perfect-Surface Copper+ conductors for stellar purity – has on music playback. Inside, NRG-4 uses a blend of solid PSC+ and PSC conductors in a self-shielding Counter-Spiral Hyperlitz configuration.

Solid conductors prevent strand interaction, the greatest single source of distortion in an audio cable or an AC power cable. PSC+ copper's exceptionally high-purity, nearly perfect surface finish, and refined interior grain structure dramatically reduce distortion compared to OFHC or other metals.

Finally, the Counter-Spiral geometry minimizes conductor interaction while maintaining a fixed low-inductance relationship between conductors. Audition NRG-4 risk-free in your home and experience the benefits for yourself. Your satisfaction is backed by our 100% Music Direct Guarantee.
