AudioQuest Fog Lifter Kit - Set of 8 Cable Elevators for Hi-Fi Speaker Wires - Reduce Vibration & Improve Sound Quality for Home Theater and Audiophile Systems

Fog Lifter Kit Place an absolute minimum of solid material in direct contact with the cableReduce the RF noise that capacitively couples into cables through all solid materials (carpet, stone, wood, etc.)Preserve low-level audio signalsFor use with audio and AC power cablesEach package includes 8 Fog LiftersDimensions: 5.6” x 5.6” (footprint); 6.25” (height) Features A few inches or centimeters might not seem important, but as with light coming from a bulb, the energy falls off exponentially. 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. Conventional shielding does not stop RF Noise from being capacitively coupled into signal-carrying conductors 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. 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. 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. 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 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.
