Developed through decades of cartridge design and refinement, it reflects a continuous pursuit of musical accuracy, control, and resolution.\u003c\/p\u003e\n\u003cp\u003eBuilt around Grado’s patented moving iron flux-bridger system, Epoch4 delivers the speed and detail associated with moving coil designs while maintaining the tonal density, stability, and longevity that define Grado cartridges.\u003c\/p\u003e\n\u003cp\u003eOffered in both stereo and mono configurations, Epoch4 is designed for systems where nothing is left to chance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerformance\u003c\/strong\u003e\u003cbr\u003eEpoch4 is a low output moving iron cartridge designed for use with high-gain phono stages.\u003c\/p\u003e\n\u003cp\u003eIts presentation is defined by clarity, separation, and control. Detail is revealed without exaggeration, with a top end that remains smooth and composed. The midrange carries natural weight and texture, while low frequencies are delivered with authority and precision.\u003c\/p\u003e\n\u003cp\u003eComplex recordings are resolved with ease, maintaining separation and spatial accuracy without collapsing the soundstage. The overall balance allows the character of the recording to come through naturally.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFlux-Bridger Moving 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\u003eThe design also ensures long-term consistency, maintaining performance over time without degradation of the internal signal path.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDiamond \u0026amp; Cantilever\u003c\/strong\u003e\u003cbr\u003eEpoch4 features a nude Shibata diamond mounted to a sapphire 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 sapphire cantilever—known for its rigidity and resistance to deformation—the system delivers clarity, extension, 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 OCC copper with gold plating, chosen for its conductivity and long-term reliability.\u003c\/p\u003e\n\u003cp\u003eEach cartridge undergoes cryogenic treatment during both component preparation and final assembly, helping to stabilize materials and optimize performance.\u003c\/p\u003e\n\u003cp\u003eThe internal structure is carefully damped to reduce unwanted resonance and vibration, allowing the cartridge to extract information from the groove with minimal interference. The result is a signal that remains coherent, balanced, and dynamically responsive.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHousing\u003c\/strong\u003e\u003cbr\u003eThe Epoch4 is housed in a Brazilian Ebony wood body.\u003c\/p\u003e\n\u003cp\u003eBeyond its visual presence, the wood plays a role in controlling resonance and contributing to the cartridge’s tonal balance. The structure has been refined to reduce mass while improving compatibility across a wider range of tonearms.\u003c\/p\u003e\n\u003cp\u003eThe form also improves visibility of the cantilever during setup, allowing for more precise alignment.\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.
