Nordost QRT QKore 3 ground box

I have a used Nordost QKore3 ground box for sale. A total of 3 2M RCA to banana ground cables are included. 

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 QKORE3 is named for its three available binding posts, which can be used to ground any component in your system on the secondary side of a power supply, where the audio circuit is. 

The QKore3 is in very good to excellent condition. It is listed for US$4100 and the 2M ground wire is listed at US$450 each. You can have the whole package for only US$3000 shipped within Cont. USA and Canada.

I accept Paypal F&F option or please add 4% for the fee.
