Grado Prestige Green 4
$140.00
Prestige Series
The Prestige Series delivers the performance and musicality that define Grado, with performance that leads its class. Each model is designed to provide a clear, engaging presentation while maintaining the balance and consistency expected across the lineup.
Prestige cartridges feature diamond and cantilever assemblies paired with high-purity OCC copper coils, housed in a precision die-injection molded body. This construction is engineered to provide stable tracking, reduced resonance, and reliable performance. User-replaceable styli allow for easy maintenance and long-term use, while availability in both standard mount and P-mount versions ensures broad compatibility.
Grado’s cartridge design is rooted in our patented flux-bridger moving iron principle, a path we chose after pioneering and patenting the stereo moving coil cartridge. While moving coil designs have become widely regarded as a reference, Prestige Series cartridges demonstrate that a different approach can deliver musical accuracy and consistency with the output and stability suited for everyday listening.
The result is a series that delivers a natural, balanced presentation with clarity and energy, offering long-term reliability and performance that exceeds expectations within its class.
Green4
Green4 is part of the Grado Prestige Series, delivering the core performance and musical character that define Grado cartridges. Built on decades of cartridge design, it provides a stable and engaging presentation across a wide range of systems.
Utilizing Grado’s moving iron design, Green4 offers a consistent and reliable signal with low moving mass and long-term performance. The die-injection molded housing supports dependable construction and ease of use.
Offered in both standard mount and P-mount configurations, Green4 is designed for broad compatibility.
Performance
Green4 is a high output moving iron cartridge designed for compatibility with a wide range of phono stages.
Its presentation is balanced and musical, with clear detail and a smooth top end. The midrange carries warmth and presence, while low frequencies remain controlled and well defined.
Recordings are presented with coherence and stability, maintaining a natural and engaging character that reflects the music.
Diamond, Cantilever & Stylus
Green4 features a bonded elliptical diamond mounted to an aluminum cantilever.
The elliptical profile provides effective groove contact and reliable tracking, while the aluminum cantilever contributes to a stable and balanced presentation. This combination delivers consistent performance across a wide range of recordings.
The stylus assembly is user-replaceable, allowing for easy maintenance and long-term ownership. All Prestige Series styli are interchangeable, providing flexibility across models while maintaining consistent performance.
Moving Iron Design
All Grado cartridges utilize a moving iron design built on Joseph Grado’s patented flux-bridger principle.
This approach allows the cartridge to generate a precise signal with extremely low moving mass, while keeping the coil structure fixed. The result is a presentation that combines speed, control, and harmonic integrity without the fragility often associated with traditional moving coil systems.
The design also ensures long-term consistency, maintaining performance over time without degradation of the internal signal path.
Coil & Internal Structure
The internal signal path is built using ultra-high purity 5N OCC copper, selected for its conductivity and consistency.
Each cartridge undergoes cryogenic treatment and internal damping to reduce unwanted resonance and preserve signal integrity. The result is a presentation that remains coherent, balanced, and dynamically responsive.
