QKORE Reviews

We’ve received some fantastic reviews and awards over the years for our products. When we get new reviews, we do our best to make sure that everyone knows. We spread the word through social media, blogs, emails, and tell anyone willing to listen! However, once the press starts piling up, and new products start to get their time in the spotlight, these amazing reviews can tend to be forgotten.

While you always have access to these great reviews, thanks to the Reviews Page on the Nordost website, we want to make sure that if you are considering an upgrade, or just want to learn more about a specific product, you can do so easily. This is especially true with a product like the QKORE. Nordost QKORE Units are parallel grounding devices, which provide an artificial, “clean” earth for hifi audio systems by drawing stray high-frequency noise and voltage-generated magnetic fields to a manufactured earth point through using both an electrical and mechanical approach. There is A LOT to learn about our QKORE units, and the in-depth reviews that these products have received are a great starting point to understanding how they work, and what their benefits are! 

This blog puts together some of our favorite QKORE and QKORE Wire reviews, so that you can access all of these informative articles at once! 


The Absolute Sound: Nordost QKORE Grounding System – Silence is Golden 

“…the elegance, the poignancy, the fragility of a musical line is what conveys the emotion at the heart of music. This is what the Nordost QKORE does so well. I can’t help thinking that to achieve the most from any high-end stereo Nordost QKORE is an essential product to consider” – The Absolute Sound

Stereophile: Nordost QKORE and QKORE Wire – System Grounding Accessories 

“I can’t imagine that anyone who’s invested considerable time and energy and money in a high-end system would want to be without the markedly ‘blacker’ backgrounds, increased transparency and detail, more vivid colors, and greater overall veracity delivered by Nordost’s QKore Ground Units…The law of diminishing returns does not apply; the differences were cumulative, and anything but subtle.”  – Stereophile


Hi-Fi+: Nordost QKORE Ground Units 

“The QKORE was like a quick lesson in ‘time coherence’, giving any sound (even speech) a more accurate sense of rhythmic beat and metre (we often just lump this together into saying it ‘times’ well). There are other benefits, too; the almost clichéd ‘darker backgrounds’ and wider soundstage with better separation of images applied here, too. The treble seemed to integrate slightly better with the midrange and bass as well, but it’s that bass and temporal correctness that wins you over. It’s like your system no longer has to apologise for itself, even if it had little to apologise for before you QKORED it!” – Hi-Fi+

Part-Time Audiophile: Nordost QKORE Ground Units and QKORE Wire

“When the time came for me to remove the Nordost QKORE grounding units from the system, I noticed the difference immediately… I felt my system lost just a bit of its edge and clarity.” – Part-Time Audiophile


Positive Feedback: Nordost QKORE Ground Products

“In advance of installing the QKORE Ground Units, I had imagined what such a product might accomplish. Those daydreams were prophetic—the only surprise was how significant it turned out to be…  it did more to improve my sound than any alternative I can think of at that price.” – Positive Feedback

PF Writers' Choice Award 2020

Positive Feedback: Nordost Premium QKORE Wire

“The major impact of the Premium QKORE wires is purity of the high frequencies. Secondary effects include increased image mass, a boost in dynamics, and dialing in focus. On the subjective side, there’s more drama and impact… If you’ve already invested in the Nordost QKORE solution, this one’s a no-brainer.” – Positive Feedback


High Fidelity: Nordost QRT QKORE6

“…connecting all elements in our system to the artificial ground is equivalent to replacing any of its elements with a superior one. But – and here it starts to be interesting – we get more of everything that we already have in the system, not something completely new. In other words, the sound we worked for, polished and refined, will be improved, not changed.” – High Fidelity

The Audio Beat: Nordost QKORE Grounding System

“[The] purist recordings of small ensembles…made plain QKORE’s contributions, as the recording venue sounded bigger and the musicians more in-the-room present, no ‘maybe’ about it. This occurred across recordings and components, QKORE expanding musical horizons and making everything in them sound more vivid—more grounded, you could say.” – The Audio Beat 

Audio Beat Award

Soundstage! Australia: Nordost QKORE 1 Ground Unit

“What the QKORE1 then does by giving a musical blood transfusion to each and every audio component, and to so clearly and audibly ‘AC lift’ the performance of my entire system, is genuinely astounding.” – Soundstage! Australia 


NOVO: Nordost QRT Power Products Review. Part 2 of 3: QKORE Ground Unit and QKORE Wire

“…the Nordost QRT QKORE6 and QKORE Wires provided enhanced benefits on a scale I would be hard-pressed to live without; benefits that could not be described as anything-less-than significant.” – NOVO 


Le Magazine Son & Image: Nordost QKORE: Benefits of Parallel Grounding

“With either the QKORE1 or QKORE3 unit in place, listening becomes engaging. There is better precision and fluidity along with a less veiled sound. A significant improvement of the sound and musical rendering emerges, an unexpected but very real effect. The results are immediate…Clarity improves across the board, very noticeable in instrumental harmonics. Vocal presence is improved, along with overall musicality from the audio system. Dynamic contrast is heightened, and a more natural and coherent rendering of sound and musical content permeates the listening room.” – Le Magazine Son & Image
