Ground Master – The Safe and Effective Way To Eliminate Ground Noise

A stable and silent Ground (or Earth) connection is crucial for maintaining the accuracy of your system voltages.

While using a clean, dedicated earth is ideal for eliminating ground-line noise, it often involves complex safety and regulatory challenges. The Puritan Ground Master addresses these issues, providing an easy, economical, and effective upgrade for audiophile systems. Enhance your listening and viewing experience effortlessly with the Ground Master.

Most modern electrical devices use high-frequency switching power supplies that dump interference into the Earth connection. Since substations often serve hundreds of homes, your HiFi Earth/Ground connection may be linked to thousands of interference-generating appliances.

Using the Puritan GroundMaster with up to 3 Ground Rods effectively identifies and channels noise and disturbance frequencies through a low-impedance route to the ground, ensuring their elimination for a cleaner, quieter connection.

• Dedicated Custom Guide Array
• 12 Individual Alternately Tuned Frequency Guides
• Simple Installation
• Kills Ground Noise Dead
• Blacker Silence and Subtler Detail
• Widens and Deepens your 3-dimensional Sound Stage
• Rock Solid, Stable Imaging

Note: Do not connect a Puritan power conditioner and a Route Master to a single Ground Master (use a separate Ground Master for each).

The Audiophile Man
“Of course, some hi-fi users might find the Ground Master impractical. Those living in flats/apartments, for example. For everyone else, as you will see below, the Ground Master can be the beginning of a rather complex array of gizmos that sit in and around the central box. You can buy varying lengths of wire, as you might expect, but you can buy extended rod lengths and you can also add a conductive soil compound in the ground, around the copper rod that, I hear, is also utilised by utility companies. I’m afraid that I was unable to test the latter. This review at least provides a start, a launch pad. From this point you can experiment and tweak to your heart’s content.”

Hi-Fi choice
“the Ground Master connected, there is definitely a noticeable reduction in the background noise in my setup. Silences between tracks seem darker and, overall, I feel that the music has a slightly improved realism. ”
