Puritan Groundmaster City

Puritan Ground Master City | Ground Noise Eliminator for Urban Environments

Cleaner Ground • Lower Noise • Enhanced Clarity

The Puritan Ground Master City brings the proven noise-elimination performance of the original Ground Master to those who can’t install a dedicated ground rod — such as apartment dwellers or users in dense urban settings. It uses your existing electrical ground connection to provide a cleaner, lower-impedance grounding path, effectively removing noise and interference from your Hi-Fi or AV system.

A Silent, Stable Reference

Your Earth (or Ground) connection is the foundation of all system voltages. Any instability or noise here directly impacts sound and image performance. The Ground Master City ensures that your reference remains as quiet and stable as possible, dramatically improving overall fidelity.

Solving the Ground Noise Problem

Most modern devices use high-frequency switching power supplies that dump electrical noise into the shared Earth line. With substations serving hundreds of homes, your Hi-Fi system may share its ground with thousands of noise-generating appliances.

The Ground Master City intercepts this pollution, providing a low-impedance route for interference to safely dissipate — restoring clarity and stability across your system.

Optimized for City Living

While the original Ground Master requires a dedicated earth rod, the Ground Master City works directly with your home’s existing ground infrastructure. Simply attach it to your Puritan power conditioner or power strip, and enjoy immediate sonic benefits — no special installation or external grounding required.
