AudioQuest Fog Lifters

Significantly Reduce RF Coupling in Cables

For four decades, AudioQuest has stated as clearly as possible, that pretty much all audio improvements come from reducing "damage" – either by preserving the original information or by not adding misinformation.

AudioQuest’s Fog Lifters are an effective upgrade because of how effectively they address a significant source of misinformation: Radio-Frequency Noise coupled from the floor into audio and AC cables.

"Expressive and Refined"

"A single Fog Lifter under each Dragon PC (for a total of four) moved my sound firmly in the direction of expressive and refined. The temptation to pile them on should be avoided… you don't want to remove all the fog," notes Marshall Nack, positive-feedback.com, September 28, 28, 2020

"The Fog Lifters confuse the fog," reports John Darko is his darko.audio review for April 2023, featured on YouTube. Darko went on to praise the Fog Lifters for their ability to produce "inky black backgrounds" and "treble as sweet as a condensed-milk sandwich."

RF Energy Is All Around Us

A carpet or wood floor, not to mention a concrete floor, might not at first seem like a source of RF Noise, but in fact RF energy is all around us and always wants to go wherever it can find a lower energy state.

Think of lightning or static electricity, especially in winter. You don’t think of yourself as an energy source, but dry heated air can make it painfully obvious that there’s an energy differential between you and the things you touch. That’s not an exact analogy, but very close.

Fog Lifters significantly reduce RF coupling, whether with the floor, or due to misdirected efforts to isolate cable with stands or clamps that themselves have too much mass and are sources of RF Noise.

A Few Inches Can Be Crucial

A few inches might not seem important, but as with light coming from a bulb, the energy falls off exponentially. A few inches can make a big difference and translate into a lower noise-floor and less distortion in attached active circuits.

If you’re thinking "my cables are shielded, so there is no noise problem," you’re partially correct. But at the high frequencies we’re bathed in thanks to cellular, Wi-Fi, and more, conventional shielding does not stop RF Noise from being capacitively coupled into signal-carrying conductors. Also, the shield itself is drained to a ground plane, which is in a sense as sensitive as the signal, because "signal" is the difference between signal and ground.

Fog Lifters come in a package of eight. Try a set and experience this upgrade for yourself. It is an easy and affordable way of improving your audio experience.
