Burn-In *

We can burn-in your cable for up to 96 hours FREE of charge using our Nordost VIDAR cable burner. This is a £3000 machine that will optimise the performance of your cables from day one. This means the cables will be in optimum performance mode when you receive them, so you'll be able to make a performance assessment quickly rather than waiting 70 hours+ of usage. The result of conditioning cables with the Nordost VIDAR is, improved sound staging, increased detail, and an overall more musical presentation. Please Note: we are unable to burn-in cables with stripped bare ends, BFA-only plugs, or no plugs selected. (This does not apply to BFA/Banana plugs). Cables are burnt-in for the selected period AFTER your order has been processed. This service is offered at Future Shop's discretion and we cannot guarantee all burn-in requests are fully completed during busy periods.

AudioQuest NRG-Z3 Mains Power Cable

 

Following on from the success of the Storm Series NRG power cables (Thunder, Tornado, Hurricane & Dragon), AudioQuest have utilised trickle down techniques to create a new series of affordable, entry level NRG power cables. Featuring the excellent Noise-Dissipation technology employed in the Storm Series, this new range of NRG-Y and NRG-Z cables outperform their old NRG-X and NRG-1/1.5/2 counterparts by a landslide. The NRG-Z3 replaces the NRG-2 however it outperforms previous higher models.

Ideal for video displays, powered speakers, and all electronics, NRG-Z3 (3-pole) cables use direction-controlled Perfect-Surface Copper (PSC) conductors in a Semi-Solid Concentric arrangement in which the individual copper strands are packed more tightly and never change position within the bundle. This construction significantly reduces strand interaction distortion. The astonishingly smooth and pure Perfect-Surface conductors minimize distortion caused by grain boundaries and surface discontinuities that exist in any metal conductor. In addition, NRG-Z3's direction-controlled silver-plated shield conductors efficiently drain RF noise to ground.

Features

  • Zero Characteristic Impedance for Uncompressed Current Transfer
  • Semi-Solid Concentric Perfect-Surface Copper (PSC) Conductors
  • Direction-Controlled Conductors & Silver-Plated Shield Drains
  • Ground-Noise Dissipation Technology

 

Zero Characteristic Impedance for Uncompressed Current Transfer

A non-technical analogy for this might be that if you drop a coin in a tube with shampoo in it, no matter how wide (low resistance) that tube, the shampoo (the Characteristic Impedance) is going to get in the way (compromise current transients). Eliminating Characteristic Impedance (Zero means No in this application) is like having only air in the tube, as close to a vacuum as possible. Whether the amp is running at less than a watt or is fully maxed out, the unrestricted transients are visceral — something the whole body understands, no words required.

Semi-Solid Concentric Perfect-Surface Copper (PSC) Conductors

NRG-Z2 and NRG-Z3 cables take a step further and use Perfect-Surface Copper (PSC in Z3, PSC+ in Z2), in a 7-strand SemiSolid Concentric conductor arrangement. The astonishingly smooth and pure Perfect-Surface processed conductors minimize distortion caused by grain boundaries and surface discontinuities which exist in any metal conductor

Direction-Controlled Conductors & Silver-Plated Shield Drains

All drawn metal has a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise drains away from where it will cause distortion. The Silver-Plated shield drains efficiently remove RF noise from the line and neutral shields via the wall plug’s “ground” pin – which is why even the 2-Pole “2” models have an unexpected ground pin.

Ground-Noise Dissipation Technology

As with the Storm Series AC cables, Z3 includes AudioQuest’s Ground Noise-Dissipation Technology. AC Ground wires over protection from current-wiring faults, but they also act as antennas, picking up radio frequency (RF) noise, which bypasses component power supplies and is typically coupled directly into a system’s most sensitive audio or video circuits.

AudioQuest's Ground-Noise Dissipation System employs a commonmode phase-canceling array that yields unprecedented levels of noise dissipation and reduction across the widest bandwidth (range) of radio frequencies – dramatically lowering distortion in the attached electronics.

About AudioQuest

AudioQuest has been the largest cable supplier to the high-end specialist market for many years. AudioQuest is sold in several hundred outlets in the US and in over sixty countries. Bill Lowe (Founder) is especially pleased that this success has been possible despite his insistence that the foundation of the company, and the foundation of AudioQuest marketing, must be the performance of the product. In the audio world, many professionals have learned that it is not always convenient to listen to the products they sell … they might learn something they don’t want to know! Bill has always understood the challenge of basing the existence of AudioQuest on the performance of the product. However, to Bill, this is the only reasonable way to do business and the only acceptable way to combine his passion for music (and all things high performance), with his need to make a living.

About AudioQuest

Californian cable maker covering analogue, digital, speaker and power cables, with patented conductor and dielectric designs.

AudioQuest is based in Irvine, California, and makes cables for nearly every connection in a system: analogue interconnects, USB, HDMI and Ethernet, speaker cables and AC power cables. Its designs come back to four ideas: solid conductors, directionality, noise dissipation and the quality of the metal.

Read more about AudioQuest Show less

Conductor and metal choices come first

Solid conductors and metal quality are two of the ideas AudioQuest returns to across its range. HyperLitz, a conductor construction patented in 1988, is another. Directionality, the principle that a cable is built to carry signal in one direction, is the fourth.

Noise is treated as a separate design problem

AudioQuest lists its noise-dissipation technologies as ZERO-Tech, RF/ND-Tech and the Dielectric-Bias System, which was patented in 2004. They are applied alongside the conductor work rather than in place of it, and which ones a cable carries depends on the model and its price.

One brand across the whole system

AudioQuest also makes AC power cables, Niagara and PowerQuest power conditioners and DragonFly DACs alongside its analogue, digital and speaker cables. If you are building or upgrading a system, that means every cable in the chain, and the power feeding it, can come from one design approach.

Why we stock AudioQuest

We took AudioQuest on for HDMI. When the 1.4 spec arrived in 2009 they were the first supplier who could actually get the cables to us, at a point when almost nobody could. The power cables turned out to be just as good, and they are now a bigger part of what we sell than the HDMI ever was.

AI Review Summary — Generated from 31 Reviews

The AudioQuest NRG Z3 power cable receives consistent praise for delivering audible sonic improvements across various audio components, including amplifiers, DACs, streamers, and CD players. Customers report significant gains in noise floor reduction, detail retrieval, soundstage clarity, and bass definition, often comparing it favorably to the lower-tier NRG Y3 model and noting the value proposition justifies the cost. Build quality is described as excellent with superior copper and insulation. However, a recurring practical complaint is the cable's stiffness and inflexibility, making installation challenging and requiring careful space planning behind components; some reviewers also request shorter length options. Service from the retailer (FutureShop) receives consistent commendation. One notable criticism identifies stiffness and limited bendability as potential frustration points during setup.

Martin Ebdon
Top class cable for source components 11 September 2026
Having already purchased AudioQuest Monsoon cables for my Shunyata Venom and Power amp, I was looking for a cable of the same quality for my DAC, streamer, and CD Transport.

The AudioQuest NRG Z3 offers the same PSC Copper and noise reduction as Monsoon but with a more slender conductor cross-section, better suited to source components. They offer an immediate uplift in performance and significantly lower the noise floor.

Fabulous cables at a very good price

Well constructed cable 15 October 2025
The cable helps you to get the most out of your system. I have four of these cables in my system after purchasing two from Futureshop, and I am very happy with their performance.

I know some people may think it is a waste of money, but if you have another cable costing nearly 3 times as much in the system, it makes a lot of sense. The sound I hear through the cable is nothing short of spectacular; the bass sounds well-defined even without using the subwoofer, and I can only attribute this to the fuse upgrade. I do not get the same sound with similar cables without the fuse upgrade.

I want to thank Mark for the innumerable hours of help and advice he gave me during the purchase.

The cable is stiff, and I wish Audioquest would consider half a meter length, as 2 meters would be too long for most cases.

A step up from NRG Y3 23 August 2025
Cable is well-made and performs nicely.

A great price-to-performance ratio within the Audioquest lineup! While the NRG Z3 uses better copper than the NRG Y3 and likely has more insulation, it is also thicker and stiffer.

Therefore, you may want to leave more space at the back of your component while using this cable.

Good quality Cable 5 August 2025
This is a review of the NRG Z3 power cable. Thanks to the top service, the delivery was super quick; it arrived the next day. I have learned from experience that cables sound better over time.

With Z3, it was instantly better compared to the Merlin cable. I didn't expect too much, as it is for the power supply of my Innuos music streamer. I am writing this review after about 10 days of playing(I do play music a lot and leave it on 24/7). For some reason, now it feels louder than when I first plugged it in; I don't have to turn up the volume due to better detail. It sounds more intimate, with details projected in a way that is easy to process, and the texture is better.

If it was much cheaper, I would buy Z3 for all my components. Z3 like any audio quest is stiff, so do make sure you have the right measurement, as it doesn't bend well or bend the angle you want, it can be frustrating if it isn't a tight fit to your components(Amps, electronics etc) Ultimately I think Monsoon is the sweet spot but it is a serious stiff cable is a literal sense, but Z3 is truly decent.

It appears to have lowered the noise floor. 1 July 2025
I was pleasantly surprised at how much difference this power cable made.

I imagine it will improve with more hours on it, but I'm happy so far.
Ian Smith ✓ Verified Purchase
Amazing product 23 June 2025
Amazing product as always from Audioquest.

Incredibly well made and makes a welcome improvement to the sound of my DAC.
