Hand-assembled in Brooklyn as part of the renowned Prestige Series, this high-output transducer utilises a low-mass moving iron generator that reduces tip inertia compared to traditional moving magnet designs. It tracks vinyl grooves with precision, offering an articulate presentation that extracts rich harmonic detail from both vintage pressings and modern reissues.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eThe Hi-Fi Centre Team Take\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eLiving with the Grado Green 4 transforms everyday listening into a warm, deeply communicative musical experience that avoids listener fatigue during extended evening album sessions. The cartridge presents an organic, midrange-forward character that reproduces acoustic instruments and human vocals with believable body and dynamic weight. Groove noise remains subdued across varied pressings, allowing the listener to settle into the performance without distracting surface friction. The Grado Green 4 achieves an engaging, cohesive balance that keeps the music flowing naturally hour after hour.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Acoustic \u0026amp; Design Features\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlux-Bridger Generator:\u003c\/strong\u003e Patented low-mass moving iron architecture delivering nimble groove tracking and low electrical distortion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElliptical Diamond Stylus:\u003c\/strong\u003e Precision-ground profile mounted on an aluminium cantilever to extract fine acoustic detail without excessive groove wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrestige Series Selection:\u003c\/strong\u003e Hand-sorted unit meeting strict top-tier production tolerances for consistent channel balance and imaging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuthorized Dealer Support:\u003c\/strong\u003e Verified purchase from Hi-Fi Centre providing authentic manufacturer warranty coverage and dedicated specialist guidance.\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\u003eBrand:\u003c\/strong\u003e Grado Labs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Prestige Green 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCartridge Type:\u003c\/strong\u003e Moving Iron (MM phono input compatible)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStylus Profile:\u003c\/strong\u003e Bonded Elliptical Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCantilever:\u003c\/strong\u003e Three-piece aluminium OTL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 10 Hz – 55,000 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Voltage:\u003c\/strong\u003e 4.0 mV @ 5 cm\/s (45°)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannel Separation:\u003c\/strong\u003e 25 dB average (10 – 30,000 Hz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Load:\u003c\/strong\u003e 10k – 47k Ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInductance:\u003c\/strong\u003e 50 mH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Resistance:\u003c\/strong\u003e 660 Ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliance:\u003c\/strong\u003e 20 µm\/mN\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\u003eCartridge Weight:\u003c\/strong\u003e 6.0 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Standard 1\/2-inch\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grado","offers":[{"title":"Default Title","offer_id":46005862006837,"sku":"Green 4","price":200.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2246\/9355\/files\/GradoGreen4.jpg?v=1789575916","url":"https:\/\/hificentre.com\/products\/grado-green-4-mm-phono-cartridge","provider":"Hi-Fi Centre","version":"1.0","type":"link"}
