{"product_id":"grado-epoch-4-phono-cartridge","title":"Grado Epoch 4 Phono Cartridge","description":"\u003cp\u003eThe Grado Epoch 4 phono cartridge utilises a patented moving-iron flux-bridger generator housed in an acoustically damped Brazilian ebony body to provide reference-grade vinyl playback for discerning analogue listeners. Hand-assembled in Brooklyn, this flagship Lineage Series transducer combines ultra-high-purity copper coils with a low-mass motor mechanism to achieve moving-coil transient speed without excessive moving mass. The assembly couples a nude Shibata diamond to a solid sapphire cantilever, ensuring precise groove tracking and extended high-frequency resolution across complex pressings.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eThe Hi-Fi Centre Team Take\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eLiving with the Epoch 4 transforms domestic playback into an intimate, fatigue-free listening experience that reveals the layered spatial acoustics of familiar pressings. The low 1.0 mV output delivers background quietness and dynamic freedom, allowing fine instrumental textures to emerge naturally during quiet late-night sessions. Its organic tonal balance and structural damping eliminate harsh mechanical resonances, presenting records with consistent composure and physical weight. It is an enduring investment for serious music lovers who demand absolute groove fidelity without sonic colouration.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Acoustic \u0026amp; Design Features\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSapphire Shibata Assembly:\u003c\/strong\u003e Combines a rigid sapphire cantilever with a nude diamond profile to maximise groove contact and high-frequency resolution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlux-Bridger Generator:\u003c\/strong\u003e Employs a low-mass moving-iron architecture to deliver swift transient response while retaining exceptional harmonic stability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrazilian Ebony Body:\u003c\/strong\u003e Utilises dense hardwood construction to dissipate internal mechanical vibrations and preserve natural acoustic timbre.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuthorized Dealer Assurance:\u003c\/strong\u003e Purchased through Hi-Fi Centre as an authorized dealer, guaranteeing authentic manufacturer warranty coverage, dedicated customer support, and factory retipping access.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransducer Type:\u003c\/strong\u003e Low-output moving iron (Flux-Bridger)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCantilever:\u003c\/strong\u003e Solid sapphire rod\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStylus Profile:\u003c\/strong\u003e Nude Shibata diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e Brazilian ebony hardwood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Voltage:\u003c\/strong\u003e 1.0 mV at 5 cm\/s (45°)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 5 Hz – 75,000 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannel Separation:\u003c\/strong\u003e 30 dB average (10 Hz – 30,000 Hz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Resistance:\u003c\/strong\u003e 95 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInductance:\u003c\/strong\u003e 8 mH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Load:\u003c\/strong\u003e 10,000 – 47,000 ohms (non-sensitive to capacitive load)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTracking Force Range:\u003c\/strong\u003e 1.6 – 1.9 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliance:\u003c\/strong\u003e 20 μm\/mN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCartridge Weight:\u003c\/strong\u003e 10.5 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Conductor:\u003c\/strong\u003e Ultra-high purity continuous-cast copper (UHPOCC)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grado","offers":[{"title":"Default Title","offer_id":46006039707701,"sku":"Epoch 4","price":17000.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2246\/9355\/files\/GradoLineage.jpg?v=1789590614","url":"https:\/\/hificentre.com\/products\/grado-epoch-4-phono-cartridge","provider":"Hi-Fi Centre","version":"1.0","type":"link"}
