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\u003eMaster4 features a nude elliptical diamond mounted to a machined boron cantilever.\u003c\/p\u003e\n\u003cp\u003eThe elliptical profile provides effective groove contact and detail retrieval, while the machined boron cantilever—known for its low mass and responsive behavior—contributes speed, stability, and a controlled, natural presentation.\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 Master4 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\u003eWood Cartridge Upgrade Program\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.
