Developed through decades of cartridge design, it brings a high level of performance to a wider range of systems while maintaining the tonal integrity that defines Grado cartridges.\u003c\/p\u003e\n\u003cp\u003eBuilt on Grado’s moving iron design, Reference4 delivers a stable and highly responsive presentation with low moving mass and long-term consistency.\u003c\/p\u003e\n\u003cp\u003eOffered in both stereo and mono configurations, Reference4 continues the tradition of Grado’s wood body cartridges.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerformance\u003c\/strong\u003e\u003cbr\u003eReference4 is available in both high and low output configurations, allowing for compatibility across a wide range of phono stages.\u003c\/p\u003e\n\u003cp\u003eIts presentation is defined by clarity, refinement, and control. Detail is resolved with precision while maintaining a smooth and composed top end. The midrange carries natural presence and texture, and low frequencies are delivered with definition and authority.\u003c\/p\u003e\n\u003cp\u003eComplex passages are handled with ease, maintaining separation and spatial stability. The overall balance remains even and composed, allowing the structure of the recording to come through naturally.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMoving Iron Design\u003c\/strong\u003e\u003cbr\u003eAll Grado cartridges utilize a moving iron design built on Joseph Grado’s patented flux-bridger principle.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDiamond \u0026amp; Cantilever\u003c\/strong\u003e\u003cbr\u003eReference4 features a nude Shibata diamond mounted to a machined boron cantilever.\u003c\/p\u003e\n\u003cp\u003eThe Shibata profile is highly effective at retrieving detail from the groove, offering exceptional contact and resolution while maintaining a natural, unforced presentation. Paired with a machined boron cantilever—known for its low mass and responsive behavior—the system delivers clarity, speed, and stability across the frequency range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCoil \u0026amp; Internal Structure\u003c\/strong\u003e\u003cbr\u003eThe internal signal path is built using ultra-high purity 6N OCC copper, selected for its conductivity and consistency.\u003c\/p\u003e\n\u003cp\u003eEach cartridge undergoes cryogenic treatment and internal damping to reduce unwanted resonance and preserve signal integrity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHousing\u003c\/strong\u003e\u003cbr\u003eThe Reference4 is housed in an American Osage wood body, selected for its ability to help control resonance and contribute to the cartridge’s tonal balance. The reshaped housing improves visibility of the cantilever during setup, allowing for more precise alignment while supporting compatibility across a wide range of tonearms.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWood Cartridge Upgrade Program\u003c\/strong\u003e\u003cbr\u003eGrado wood body cartridges are supported through our Wood Cartridge Upgrade Program.\u003c\/p\u003e\n\u003cp\u003eThis program allows you to move from your current Grado wood cartridge to another model, with a pricing accommodation provided through the program.
