“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 . . .”

“I am reticent to say it, but once you try them, you might find the QKORE Ground Products as indispensable as I did. This is the kind of upgrade that doesn’t come along every day.”

“These are not “additions”, but as important elements of the audio system as any other ones…I have got used to it and to what it does to the sound of my player so fast and so strongly that I experienced physical pain when I was putting the device back into the box … ”

“The QKore grounding system truly demonstrates that silence is golden. It represents an ingenious attempt to combat the electronic nasties that conspire to corrupt the sound of electronic musical reproduction. Unlike many products that purport to produce a purer sound, the QKore is a non-invasive grounding device that you plug into an unused input on a stereo component; it produces no extra-musical artifacts of its own. What it does is create a much blacker background from which the subtlest of details emerge with elegance and refinement. Every part of the sonic spectrum will also sound fuller and more transparent. For any high-end enthusiast seeking to improve his system, this is an essential component.”
