Ground Your System and Rid Imperfections Caused by Bluetooth, Wi-Fi, and Cell Signals: Nordost QKORE Ground Units Lower the Noise Floor, Enhance Harmonics, and Improve Overall Musicality

Nordost QKORE ground units provide your system with the industry's most comprehensive grounding solution, creating a clean earth ground point that rids imperfections in the power domain caused by today's abundant Bluetooth, Wi-Fi, and cell signals. Using an electrical and mechanical approach, the Hi-Fi+ Product of the Year Award-winning and The Absolute Sound Golden Ear Award-winning QKORE defeats airborne pollution such as high-frequency interference, noise, and stray magnetic fields – resulting in a dramatically lower noise floor, enhanced harmonic accuracy, elevated clarity, and improved musicality you'll instantly hear. 100% Music Direct Guaranteed.

Combining Nordost's patented Mono-Filament technology with purpose-built, Low-Voltage Attractor Plates (LVAPs) – and constructed with a proprietary metal alloy and passive electronic circuit as to draw stray high-frequency noise and voltage-generated magnetic fields to a manufactured earth point – the completely passive QKORE provides your system with a clean, balanced reference. QKORE resides in mechanically tuned housing and arrives outfitted with gold-plated WBT binding posts that easily connect each component to an artificial ground. As QKORE establishes a balanced, extremely clean ground point, byproducts of electrical balance imperfections between voltage and ground are no longer added to other pollutants, resulting in increased high-quality circuit performance.

Nordost also designed a designated QKORE Wire constructed to provide the path of least resistance to ground for the stray, high-frequency, low-voltage potentials that can impact the sound of your system. A mechanically tuned cable that utilizes Nordost's patented Micro Mono-Filament technology, QKORE Wire features extruded FEP insulation and a 16 AWG, silver-plated OFC, solid-core conductor. The QKORE Wire can be terminated with the following connectors: spade, banana, male-XLR, female-XLR, BNC, and RCA.

"The main effect was in the bass, which sounded significantly tighter, deeper, and more authoritative. More significantly, QKORE was like a quick lesson in 'time coherence,' giving any sound (even speech) a more accurate sense of rhythmic beat and meter."
—Alan Sircom, Hi-Fi+

"Sure, the blockbuster stuff can be thrilling and will definitely impress your chums. But the elegance, the poignancy, the fragility of a musical line is what conveys the emotion at the heart of the music. This is what the Nordost QKore does so well."
—Jacob Heilbrunn, The Absolute Sound, Golden Ear and Editors' Choice Awards

"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."
—Jason Serinus, Stereophile

"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."
—Peter Katsoolis, SoundStage! Australia

QKORE is available in three distinct models, each created for specific system needs: Offering an effective ground on the primary side of the power supply (QKORE1), offers grounds on the secondary side of the power (QKORE3), and offers grounds to a full system anchored by monoblocks (QKORE6).

QKORE1 is specifically designed to serve as a parallel ground for use with Nordost's QBASE distribution block. Connecting QBASE to QKORE1's singular binding post provides an effective, alternative ground on the primary side of the power supply. Comes with a 2M Banana to Banana QKORE Wire and furnished with one QBASE Ground binding post to ground your distribution block.

QKORE3 is named for its three available binding posts that can be used to ground any component in your system on the secondary side of a power supply (the location of the audio circuit). Provided with a 2M RCA to Banana QKORE Wire. Also furnished with three multi-use binding posts to ground your audio circuitry.

QKORE6 is designed for monoblock users and makes it possible to ground all elements of your sound system on its binding posts – including one ground for your distribution block, two grounds for the left and right channels of your monoblocks, and three grounds for additional audio components. Provided with a 2M Banana to Banana QKORE wire and a 2M RCA to Banana QKORE Wire. Also furnished with three multi-use binding posts for audio circuitry, two binding posts for left and right monoblocks, and one QBASE Ground binding post to ground your distribution block.
