Performance<\/h2>

Green4 is a high output moving iron cartridge designed for compatibility with a wide range of phono stages.<\/p>

  • Its presentation is balanced and musical, with clear detail and a smooth top end.<\/li>
  • The midrange carries warmth and presence, while low frequencies remain controlled and well defined.<\/li>
  • Recordings are presented with coherence and stability, maintaining a natural and engaging character that reflects the music.<\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    Diamond, Cantilever & Stylus<\/h2>

    Green4 features a bonded elliptical diamond mounted to an aluminum cantilever.<\/p>

    • The elliptical profile provides effective groove contact and reliable tracking.<\/li>
    • The aluminum cantilever contributes to a stable and balanced presentation.<\/li>
    • This combination delivers consistent performance across a wide range of recordings.<\/li>
    • The stylus assembly is user-replaceable, allowing for easy maintenance and long-term ownership.<\/li>
    • All Prestige Series styli are interchangeable, providing flexibility across models while maintaining consistent performance.<\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

      Moving Iron Design<\/h2>

      All Grado cartridges utilize a moving iron design built on Joseph Grado\u2019s patented flux-bridger principle.<\/p>

      • This approach allows the cartridge to generate a precise signal with extremely low moving mass, while keeping the coil structure fixed.<\/li>
      • The result is a presentation that combines speed, control, and harmonic integrity without the fragility often associated with traditional moving coil systems.<\/li>
      • The design also ensures long-term consistency, maintaining performance over time without degradation of the internal signal path.<\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

        Coil & Internal Structure<\/h2>

        The internal signal path is built using ultra-high purity 5N OCC copper, selected for its conductivity and consistency.<\/p>

        • Each cartridge undergoes cryogenic treatment and internal damping to reduce unwanted resonance and preserve signal integrity.<\/li>
        • The result is a presentation that remains coherent, balanced, and dynamically responsive.<\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
