The Black Hole GroundGoody by AudioQuest is an innovative grounding cable designed to eliminate noise and significantly enhance the sound quality of your audio system. This high-tech product represents a major advancement in grounding cables, offering an effective solution to hum and radio frequency (RF) interference issues that can affect the performance of your high-end audio equipment.
The Black Hole GroundGoody stands out for its advanced technical design. AudioQuest has developed a conductor made of long-grain copper (LGC) coated with 6% silver. This combination provides exceptional conductivity while minimizing distortions. The unique feature of this cable lies in its “carbon RF trap,” an innovation that uses conductive PVC to effectively dissipate RF noise before it can be induced into the main conductor.
This unique approach allows the Black Hole GroundGoody to function not just as a simple grounding wire but as a true shield against electromagnetic interference. Unlike traditional grounding cables that can sometimes act as antennas and pick up noise, the Black Hole GroundGoody actively neutralizes them.
The manufacturing quality of the Black Hole GroundGoody matches its technological ambitions. The conductors are direction-controlled, ensuring optimal performance in the signal’s flow direction. Connections are made using cold-welded silver-plated spade lugs, guaranteeing a perfect and durable bond.
This attention to detail is also evident in the design of the carbon RF trap. The use of conductive PVC is not only a technical achievement but also a choice that contributes to the cable’s durability and reliability over time.
Using the Black Hole GroundGoody can have a remarkable effect on your system’s sound quality. By effectively eliminating noise and RF interference, this cable allows music to emerge from a quieter background. Attentive listeners will notice:
These improvements are particularly noticeable when listening to vinyl, where the very low signal from the phono cartridge is especially sensitive to interference.
The Black Hole GroundGoody stands out with its carbon RF trap technology and silver-coated LGC copper conductors. Unlike standard cables that can sometimes act as antennas, it actively dissipates RF noise, providing more effective grounding and better sound quality.
Yes, the Black Hole GroundGoody is compatible with most turntables equipped with a grounding point. It can also be used with other audio equipment requiring grounding, such as phono preamps or certain amplifiers.
Direction control ensures that the metal crystals in the conductor are optimally aligned for signal flow. This can reduce micro-distortions and improve the overall signal quality.
The carbon RF trap uses conductive PVC to create a barrier that absorbs and dissipates RF interference before it reaches the main conductor. This allows for more effective noise reduction compared to traditional grounding cables.
For many listeners, the difference is noticeable. Typically, there is a reduction in background noise, improved sound clarity, and a more precise stereo image. The extent of the improvement may vary depending on your system and listening environment.

Unlike in the photo, this ground cable is very thin, really very thin and stiff, but nevertheless it does its job.
