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 work so well because of how effectively they address a significant source of misinformation—Radio-Frequency Noise coupled from the floor into audio and AC cables.
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 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.
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, etc., conventional shielding does not stop RF Noise from being capacitively coupled into signal-carrying conductors—not to mention that 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.
Place an absolute minimum of solid material in direct contact with the cable
Reduce the RF noise that capacitively couples into cables through all solid materials (carpet, stone, wood, etc.)
Preserve low-level audio signals
For use with audio and AC power cables
Each package includes 8 Fog Lifters

After carefully suspending all the power and signal cable connections of the elaborate system, I was amazed at the undoubtedly enormous gain in sound.
