When you power on your home audio system and turn it up, you don’t just bring the noise, chances are, you’ve got too much of it already in the form of AC-born (-/e) electrical noise. The AC power line is the lifeblood of a home audio system and its quality is critical to a system’s ultimate performance no matter how well designed the power supplies of your individual components. But what you are hearing (and therefore not hearing, as it were) is a function of...

I thought I’d gone about as far as you could to eliminate noise and hash riding on the power lines. It now turns out that I was quite wrong. Nordost’s Michael Taylor visited this somewhat skeptical reviewer, and the conversion process went rather quickly. Facts, as Thomas Gradgrind likes to say in Dickens’ Hard Times, are what boys and girls need. And in this instance, the cold hard fact is that the introduction of the Nordost QKore parallel grounding device into my...

Even with the breakneck pace of advancement in the consumer-electronics industry, high-end audio has remained rather staid, the not too-recent rise of high-resolution file playback notwithstanding.

Sometimes we as journalists are privy to way prior to their launch. Such is the case with Nordost’s QKORE trio of ground units.
