AudioQuest - Fog Lifters Cable Uppers to Isolate RF Noise - Black

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.
