That low hum or buzz coming through your speakers usually isn't a failing amp — it's a ground loop. When two components in your system sit at slightly different ground potentials, stray current flows through your signal cables and gets amplified as a steady 60Hz hum, buzz, or static crackle.
What this grounding cable does
This silver-plated grounding cable connects a component's ground point or unused input to a common ground path, giving stray voltage and static a low-resistance route to drain away instead of through your audio signal. The result: reduced hum, less buzz, and a lower noise floor — without touching your source signal.
Works with
Integrated, tube, and power amplifiers
DACs and headphone amps
Phono preamps and turntables
Powered speakers and subwoofers
CD players, streamers, and other line-level sources
Choosing your variant
RCA termination – plugs into an unused RCA input/output on your component. Available with a rosewood or paper-tube barrel.
Y-plug termination – connects to a chassis ground screw or grounding post (ideal for turntables and amps with a dedicated GND terminal).
USB termination – grounds through a spare USB port, handy for DACs, streamers, and desktop audio setups.
Clip-plug termination – alligator-style clip that attaches to any exposed chassis or ground point, no screw terminal needed.
18AWG vs 24AWG silver conductor – 18AWG offers a heavier, lower-resistance ground path; 24AWG is a lighter, more flexible option for desktop setups.
Frequently asked questions
What causes ground loop hum? Multiple components plugged into different outlets or power strips can sit at slightly different ground potentials. Current flowing between them through interconnects is heard as a constant 60Hz hum or buzz.
Will this affect sound quality? It sits outside the signal path, so it doesn't alter your audio signal. Its job is purely to drain noise-causing stray voltage. Results vary with the cause of the noise — grounding accessories are most effective against ground-potential hum and static, less so against RF interference.
How do I install it? Plug the RCA or USB end into an unused port, attach the Y-plug to a chassis ground screw, or clip the alligator end to any exposed ground point. No tools, power, or configuration required.
