AudioQuest NRG-Z3 Power Cable - 3.28' (1m)

The NRG-Y2, NRG-Y3, NRG-Z2, and NRG-Z3 AC cables utilize the same get-out-of-the-way and Noise-Dissipation technologies as the NRG Storm Series of AC cables. These models all feature Zero Characteristic Impedance for Uncompressed Current Transfer. To put it simply, this means that the current transfer is not compromised by any impedance, much like how a coin dropped in a tube filled with shampoo would encounter resistance no matter how wide the tube is. By eliminating the Characteristic Impedance, the current transfer is as smooth as possible, similar to a vacuum.

Whether the amplifier is running at a low wattage or at maximum output, the unrestricted transients are felt and understood by the body, without the need for words. The NRG-Z2 and NRG-Z3 cables take it a step further by using Perfect-Surface Copper (PSC in Z3 and PSC+ in Z2), arranged in a 7-strand Semi-Solid Concentric conductor configuration. This unique construction minimizes distortion caused by grain boundaries and surface discontinuities that are present in any metal conductor.

Furthermore, all the new models feature Direction-Controlled Conductors and Silver-Plated Shield Drains. AudioQuest ensures that the resulting RF impedance variation is controlled, allowing noise to drain away from where it could cause distortion. The Silver-Plated shield drains efficiently remove RF noise from the line and neutral shields via the ground pin of the wall plug, which is why even the 2-Pole 2 models have an unexpected ground pin.

In addition, the NRG-Z3 also incorporates AQ's Ground-Noise Dissipation Technology, which is protected by a US Patent (# 8988168). This technology, similar to what is found in the Storm Series AC cables, helps to dissipate ground noise. While AC ground wires provide protection against current-wiring faults, they can also act as antennas, picking up RF noise that can bypass the power supply of components.

Overall, with the use of Perfect-Surface Copper, Silver-Plated Drain Wires, and the implementation of Ground-Noise Dissipation Technology, the NRG-Y2, NRG-Y3, NRG-Z2, and NRG-Z3 AC cables provide quiet background and minimal active-circuit misbehavior. They also ensure uncompressed current transfer with zero characteristic impedance, resulting in exceptional audio performance.
