Puritan Groundmaster

Puritan Ground Master | Advanced Ground Noise Eliminator

Eliminate Ground Noise • Enhance Clarity • Protect Your System

The Puritan Ground Master is the safe, effective, and high-performance solution to eliminate ground-line noise from your Hi-Fi or AV system. Designed to deliver a clean, stable, and silent ground reference, it unlocks the full potential of your equipment — improving detail, dynamics, and soundstage depth.

Why Ground Noise Matters

Your Earth (or Ground) connection forms the absolute voltage reference for your entire system. Any instability or noise here can subtly degrade performance — flattening dynamics, adding harshness, and obscuring fine detail.

Modern homes are filled with switch-mode power supplies that dump high-frequency noise back into the shared Earth line. With substations often serving hundreds of homes, your Hi-Fi’s ground may be linked to thousands of noise-polluting devices.

How the Ground Master Works

Used in conjunction with a dedicated ground rod, the Puritan Ground Master identifies and channels unwanted interference and disturbance frequencies through a low-impedance route to ground — safely and effectively eliminating them from your system.

This means a blacker background, tighter imaging, and a more immersive three-dimensional soundstage.
