Grado Gold4

Gold4 Description Gold4 represents the highest level of performance within the Grado Prestige Series. Built on decades of cartridge design and refinement, it delivers a balanced and highly musical presentation while maintaining the consistency and reliability that define Grado cartridges. Utilizing Grado’s moving iron design, Gold4 provides a stable and responsive signal with low moving mass and long-term performance. The die-injection molded housing supports consistent construction while allowing the internal components to perform with precision. Offered in both standard mount and P-mount configurations, Gold4 is designed for a wide range of systems. Specifications Output - 4 mV 5 CMV (45 degrees) Frequency Response-10-55,000 Hz Channel Separation - Average 25 DB, 10-30,000 Hz Stylus - Diamond- Elliptical Input Load 10k - 47k ohms Induction - 50 mH DC Resistance 660 ohms Cartridge Weight - 6 grams Tracking Force 1.6-1.9 grams Compliance - 20 um/mN - Mounting - P-mount or 1/2" Screw Mount Performance Gold4 is a high output moving iron cartridge designed for compatibility with a wide range of phono stages. Its presentation is defined by clarity, control, and refinement. Detail is resolved with precision while maintaining a smooth and composed top end. The midrange carries natural presence and texture, while low frequencies are delivered with definition and authority. Complex recordings are handled with stability and separation, maintaining a coherent and balanced presentation that allows the character of the music to come through naturally. Diamond, Cantilever & Stylus Gold4 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 controlled presentation. Together, they deliver clarity, balance, and consistency 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.

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.
