Platinum4 is part of the Grado Timbre Series, offering a balanced and accessible entry into Grado's wood body cartridge designs. Built on decades of cartridge development, it delivers clarity, stability, and musicality while maintaining the tonal character that defines Grado cartridges.

Utilizing Grado's moving iron design, Platinum provides a consistent and reliable signal with low moving mass and long-term performance.

Offered in both stereo and mono configurations, Platinum continues the tradition of Grado's wood body cartridges.

Performance

Platinum4 is available in both high and low output configurations, allowing for compatibility across a wide range of phono stages.

Its presentation is balanced and controlled, with clear detail and a smooth, natural top end. The midrange carries presence and body, while low frequencies remain defined and composed.

Recordings are presented with stability and coherence, maintaining separation and imaging while allowing the character of the music to come through.

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.

Diamond, Cantilever & Stylus

Platinum4 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.

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.
