Sonata4 is part of the Grado Timbre Series, representing a refined balance of resolution, control, and musicality. Developed through decades of cartridge design, it delivers a highly engaging presentation while maintaining the tonal integrity that defines Grado cartridges. Built on Grado’s moving iron design, Sonata4 provides a stable and responsive signal with low moving mass and long-term consistency. Offered in both stereo and mono configurations, Sonata4 continues the evolution of Grado’s wood body cartridges. Sonata4 is available in both high and low output configurations, allowing for compatibility across a wide range of phono stages. Its presentation is defined by clarity, balance, and musical flow. Detail is resolved with precision while maintaining a smooth and natural top end. The midrange carries presence and texture, and low frequencies are delivered with control and definition. Recordings are presented with coherence and stability, maintaining separation and imaging while preserving the character of the music.
