AudioQuest NRG-Y2 2-Pole AC Power Cable at Vinyl Sound Toronto Canada

The NRG-Y2 is a low-distortion 2-pole AC power cable from AudioQuest (Irvine, California, USA), available at Vinyl Sound in Toronto, Canada. A step up from the NRG-X2 within AudioQuest's NRG Series, the NRG-Y2 adds silver-plated drain wires that actively route RF noise from the line and neutral shields to the ground pin, alongside Semi-Solid Concentric Long-Grain Copper (LGC) conductors and ZERO characteristic impedance for fully uncompressed current delivery. Terminated with an IEC C7 figure-8 plug and a 3-prong North American wall plug, the NRG-Y2 is a versatile and accessible upgrade for any 2-pole-equipped audio or video component including DACs, network streamers, powered desktop speakers, gaming consoles, and Blu-ray players.

Long-Grain Copper Conductors in Semi-Solid Concentric Arrangement

The NRG-Y2 uses Long-Grain Copper (LGC) conductors in AudioQuest's Semi-Solid Concentric topology. Standard multi-strand power cables suffer from a compounding distortion mechanism: as individual strands shift position relative to each other along the cable's length, the varying electrical and magnetic contact between them generates Transient Intermodulation (TIM) Distortion that bypasses a component's internal filtering and modulates the audio signal directly. In the Semi-Solid Concentric arrangement, strands are packed tightly enough that they cannot change position within the bundle, maintaining fixed strand relationships along the entire cable length and significantly reducing this interaction distortion. The Long-Grain Copper base material adds a further refinement: its less complex grain structure and fewer internal grain boundaries produce fewer electron-path discontinuities, reducing the distortion introduced at the conductor level before the signal even reaches the component's power supply.

Silver-Plated Drain Wires and ZERO Characteristic Impedance

The NRG-Y2's defining advantage over the NRG-X2 is its silver-plated drain wire system. Even after a component's power supply filters the AC supply, the ground conductor of a standard power cable continues to act as an antenna, inducting radio-frequency noise from the surrounding environment. This RF noise bypasses the power supply entirely and couples directly into the most sensitive low-level audio and video circuits within the component. The NRG-Y2 addresses this with direction-controlled silver-plated shield conductors on both the line and neutral conductors, each equipped with a drain wire that efficiently routes the captured RF noise to the ground pin of the 3-prong wall plug, removing it from the audio circuit path before it can cause interference. The silver plating, at 0.5% of conductor mass, is applied to the copper base metal to further improve the noise-dissipation efficiency of the drain path. Combined with ZERO characteristic impedance, which eliminates the current compression that non-zero-impedance cables impose on amplifier transients, the NRG-Y2 delivers both a quieter noise floor and fully uncompressed dynamic current delivery.

Key Features

• Long-Grain Copper (LGC) Conductors: High-purity copper with fewer and longer crystalline grains than standard OFHC copper, reducing grain-boundary distortion at the conductor level for a cleaner power supply at the component.
• Semi-Solid Concentric Packed Topology: Strands are packed tightly and maintain fixed positions within the bundle along the full cable length, significantly reducing the strand-interaction Transient Intermodulation Distortion that conventional multi-strand cables produce.
• Silver-Plated Drain Wires: Direction-controlled silver-plated shield conductors on both the line and neutral arms capture RF noise induced into the cable and drain it to the ground pin via the 3-prong wall connector, preventing it from reaching connected component circuits.
• ZERO Characteristic Impedance: Combines low DC resistance with zero characteristic impedance for fully uncompressed current transfer, ensuring connected components receive their full peak current demand on demand without the dynamic compression that standard power cables impose.
• Direction-Controlled Conductors and Shields: All LGC conductors and silver-plated shield drain wires are tested and oriented for optimal RF impedance directionality, with direction arrows marked on the connectors to ensure correct installation and maximum noise drainage.
• 3-Prong North American Wall Plug: Unlike the 2-prong wall plug of the NRG-X2, the NRG-Y2 uses a 3-prong wall plug that provides the ground connection needed to drain RF noise captured by the silver-plated shield conductors, making the ground path an active part of the noise-dissipation system.
• IEC C7 Device Plug: The 2-pole C7 figure-8 plug fits the wide range of audio and video components equipped with C7 inlets, including DACs, network streamers, gaming consoles, Blu-ray players, powered desktop speakers, and set-top boxes.

Frequently Asked Questions

What is the AudioQuest NRG-Y2 power cable?

The AudioQuest NRG-Y2 is a 2-pole AC power cable using Semi-Solid Concentric Long-Grain Copper conductors, silver-plated drain wires on both the line and neutral shields, ZERO characteristic impedance, and direction-controlled installation. It uses a C7 IEC figure-8 device plug and a 3-prong North American wall plug, with the ground pin serving as the active drain path for RF noise captured by the silver-plated shield conductors from both the line and neutral conductors.

How does the AudioQuest NRG-Y2 compare to the NRG-X2 and NRG-Z3?

The NRG-Y2 sits above the NRG-X2 and below the NRG-Z3 within AudioQuest's NRG Series power cable range. The NRG-X2 is a purely 2-pole design with no ground drain path and uses a 2-prong wall plug, relying on its Semi-Solid Concentric LGC conductors and helical conductor geometry to reduce distortion. The NRG-Y2 adds silver-plated drain wires on both the line and neutral shields and a 3-prong wall plug that provides an active RF noise drain path to ground, meaningfully reducing the noise floor of connected components beyond what the NRG-X2 achieves. The NRG-Z3 moves to a full 3-pole design with a C13 IEC plug for earthed components and advances further in conductor refinement and noise-dissipation technology. For 2-pole-inlet components where a grounded wall outlet is available, the NRG-Y2 is the stronger performer of the two 2-pole options in the NRG Series.

Why does the NRG-Y2 use a 3-prong wall plug if it is a 2-pole cable?

The 3-prong wall plug on the NRG-Y2 provides a ground pin that serves as the drain path for RF noise captured by the silver-plated shield conductors on both the line and neutral arms of the cable. Although the connected component uses a 2-pole C7 inlet with no ground contact at the component end, the noise induced into the cable's shielding is routed through the silver-plated drain wires to the ground pin of the wall plug, dissipating it at the outlet before it can reach the component's circuits. This is AudioQuest's practical approach to adding an active RF noise drain to a 2-pole component cable by using the available ground connection at the wall.

What is ZERO characteristic impedance and why does it matter?

Characteristic impedance is a cable's opposition to rapidly changing current, distinct from its DC resistance. A cable with low DC resistance but non-zero characteristic impedance still compresses peak current delivery during sudden demands, such as the transient current surge a power amplifier requires on a musical peak. AudioQuest's ZERO characteristic impedance design combines low DC resistance with a cable geometry and material selection that presents zero opposition to current changes, ensuring the connected component receives its full peak current demand without compression or dynamic restriction.

What components are compatible with the AudioQuest NRG-Y2?

The NRG-Y2 is compatible with any component using a 2-pole IEC C7 figure-8 power inlet, including DACs with C7 inlets, network streamers such as Sonos players and Bluesound NODE, powered desktop speakers with C7 inlets, gaming consoles including all PlayStation and Xbox models, Blu-ray and 4K UHD players, cable and satellite set-top boxes, Apple TV, and compact audio components from brands such as Cambridge Audio, NAD, Rega, and Naim. Always verify that your specific component uses a C7 inlet before purchasing; components with a 3-pole C13 inlet require the NRG-Y3 or a 3-pole cable instead.

Where can I buy the AudioQuest NRG-Y2 power cable in Toronto or Canada?

The AudioQuest NRG-Y2 is available at Vinyl Sound, an authorized AudioQuest dealer in Toronto, Canada. Vinyl Sound carries the full NRG Series power cable range in multiple lengths and both 2-pole and 3-pole configurations and can assist with compatibility confirmation and cable selection for customers throughout the Greater Toronto Area and across Canada.

Does the direction of installation matter for the AudioQuest NRG-Y2?

Yes. All LGC conductors and silver-plated drain wires in the NRG-Y2 are tested and oriented for optimal RF impedance directionality. AudioQuest marks direction arrows on the connectors, and the cable should be installed with the arrow indicating flow from the wall toward the component. Correct orientation ensures that RF noise is efficiently drained away from the connected component rather than toward it, which is a core element of AudioQuest's noise-dissipation approach across the full NRG Series.

What lengths is the AudioQuest NRG-Y2 available in?

The AudioQuest NRG-Y2 is available in lengths of 1m, 2m, 3m, and 4.5m, accommodating compact desktop installations as well as systems where components are placed further from the wall outlet. Contact Vinyl Sound Toronto for current stock availability across lengths.
