A great deal of the electrical noise in hifi systems is caused by imperfections in the power domain. These imperfections may be generated by airborne pollution on the AC line that are induced, in part, by increasing amounts of Bluetooth, Wi-Fi, and cellular signals. Airborne pollution can take the form of high frequency interference, noise, and stray magnetic fields, which lead to AC line contamination. A poor, or “unclean”, ground causes more performance imperfections than most people realize. Without an effective ground point, the entire foundation of your sound system becomes jeopardized—and unfortunately, most listening rooms simply do not have access to a designated line, attached to a ground rod. In these instances, a simple, effective, and internal option is needed: Nordost’s QKORE Ground Unit.
The QKORE is a parallel grounding device, which provides an artificial, “clean” earth for hifi audio systems using both an electrical and mechanical approach. This unique product combines Nordost’s patented Mono-Filament technology with purpose-built, Low-Voltage Attractor Plates (LVAPs), constructed with a proprietary metal alloy and a passive electronic circuit, in order to draw stray high frequency noise and voltage-generated magnetic fields to a manufactured earth point, leaving a clean reference behind. This passive system is contained in a mechanically tuned housing, and outfitted with gold-plated, WBT binding posts, which easily connect each component to an artificial ground. By providing for a balanced and very “clean” ground point, by-products of electrical balance imperfections between voltage and ground are no longer added to other pollutants, dramatically increasing high quality audio circuit performances.
The QKORE grounding system is the most effective, comprehensive grounding solution in the consumer electronics market. When introduced to a hifi audio system, the results are immediate and dramatic— the noise floor drops, the increase in harmonic accuracy and clarity is unmistakable, and the overall musicality in system performance is elevated. Every aspect of Nordost’s QKORE grounding system is thoughtfully designed and manufactured in the USA to the highest standards in the industry, in order to ensure product quality and customer satisfaction.

But in the end it is the added refinement that the QKore provides that is the most addictive. The more I listen, the more riveting I find the ability of a good stereo to capture the nuances of the music. This is what the Nordost QKore does so will. I can't help thinking that to achieve the most from any high end stereo Nordost QKore is an essential product to consider. more...
