GroundMaster – City Master Ultra Ground Enhancer By Puritan Audio Laboratories

Unlock Your System's Full Potential with CITY MASTER ULTRA
Many audiophiles invest heavily in premium components—cartridges, DACs, preamps, amps, and speakers—to achieve superior sound. However, one critical element is often overlooked: the ground line. Ground forms half of the signal path, and without a clean, stable reference, even the finest equipment cannot deliver its full performance.

Why Ground Noise Matters
Ground lines naturally carry noise—subtle interference that distorts the signal. This doesn’t always manifest as a hum or buzz but can mask detail, reduce dynamics, and flatten the soundstage. The result? A less immersive, less accurate listening experience, regardless of gear quality.

Introducing CITY MASTER ULTRA
Building on the success of the original GroundMaster CITY, the CITY MASTER ULTRA offers enhanced noise reduction, especially in environments where installing a dedicated ground rod is not feasible—such as apartments or urban settings. Compact and powerful, it integrates easily into any high-performance audio system, delivering cleaner, more detailed sound without the need for complex installations.

Simple, Effective Integration
Designed for flexibility, the ULTRA works seamlessly with systems using Puritan power conditioners or similar power solutions. With all necessary cables included, setup is straightforward and results are immediate.

For audiophiles seeking true fidelity, the CITY MASTER ULTRA is a game-changing upgrade—improving system integrity where it matters most.
