Puritan Audio Labs Ground Master

The Ground Master targets and eliminates ground-line noise, which is often caused by modern switching power supplies in your home. By creating a low-impedance path for this interference to exit, it lowers the noise floor of your system, allowing you to hear finer musical details that were previously masked.

Yes, the Ground Master requires a dedicated earth ground rod to function effectively. It is designed to channel interference away from your equipment and into the earth, so a proper, independent ground connection is essential for the device to perform as intended.

By removing electrical noise, the device helps your system produce a more expansive, three-dimensional soundstage. You will likely notice more precise imaging and a quieter background, which makes the music feel more stable and realistic.

The twelve frequency guides are alternately tuned to target a wide spectrum of noise interference. This multi-stage approach ensures that the device can effectively identify and eliminate various types of electrical noise that standard grounding might miss.

The Ground Master is designed to work with any high-fidelity audio system that suffers from ground-line noise. Because it addresses the electrical foundation of your setup rather than the audio signal itself, it is compatible with a wide range of receivers and amplifiers.
