Grado Opus4

Opus4 is the entry point into the Grado Timbre Series, introducing the tonal character and construction of Grado’s wood body cartridges. Built on decades of cartridge design experience, it delivers a balanced and musical presentation while maintaining the core performance principles that define Grado cartridges. Utilizing Grado’s moving iron design, Opus4 provides a stable and consistent signal with low moving mass and long-term reliability. Offered in both stereo and mono configurations, Opus4 represents the foundation of the Grado wood cartridge line. Opus4 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 warmth, while low frequencies remain defined and composed. Recordings are presented with stability and coherence, maintaining separation and musical flow while allowing the character of the recording to come through naturally.
