Audioquest Fog Lifters - Cable-Uppers Isolate RF Noise, Opening Up the Sound Field

For four decades, AudioQuest has stated as clearly as possible, that almost all audio improvements come from reducing “damage”—either by preserving the original information or by not adding misinformation.

Decouple your cables from the floor.

Concrete floors eliminate Radio Frequency noise, that enters the power and Speaker cables, this blurs the sound.

Remove the Fog, Audioquest’s Foglifters work.

AudioQuest’s new Fog Lifters address a significant source of misinformation: Radio-Frequency Noise coupled from the floor into audio and AC power cables. Whether the floor is covered with carpet or made of wood or stone, the material capacitively couples RF Noise into the cable to distort the vulnerable audio signal, even when the cables are “100% shielded.”

A 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. Dry heated air can make it painfully obvious that there’s an energy differential between our bodies and the things we touch.

A few inches or centimeters might not seem important, but as with light coming from a bulb, the energy falls off exponentially. A few inches or centimeters makes a big difference—which translates into a lower noise-floor and less compromise to, and distortion in, attached active circuits.

Shielding may help, but at the high frequencies we’re bathed in thanks to cellular, Wi-Fi, etc., conventional shielding does not stop RF Noise from being capacitively coupled into signal-carrying conductors.
