{"product_id":"gradomaster3lo","title":"Grado Timbre Master3 MI Phono Cartridge (Low Output)","description":"\u003cp\u003eThe Grado Master3 is a Moving Iron phono cartridge from the Timbre series – hand-built in Brooklyn, with an Australian Jarrah wood body and a machine-crafted boron cantilever. This Low Output version delivers 1.0 mV for low-noise phono stages.\u003c\/p\u003e\n\u003cp\u003eWithin the Timbre series, the Master3 sits high up the ladder – only the Reference3 ranks above it.\u003c\/p\u003e\n\u003ch2\u003eWhy the Master3?\u003c\/h2\u003e\n\u003cp\u003eGrado builds on the Moving Iron principle with a dual-magnet (flux-bridge) system: this keeps the moving mass small and inductance low – for an open, fast sound. The machine-crafted boron cantilever and the five-piece OTL construction further reduce tip mass compared to the more affordable Timbre models and bring more control and resolution.\u003c\/p\u003e\n\u003cp\u003eTracking is handled by Grado's own specially cut, bare elliptical diamond. The coils are wound with ultra-pure UHPLC copper, and every Master3 is individually calibrated.\u003c\/p\u003e\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eThe warm, colourful Grado character, but with significantly more precision, calm and fine detail than the smaller Timbre models. The Jarrah body settles resonances and keeps the sound stable.\u003c\/p\u003e\n\u003ch3\u003eWho is the Low Output version for?\u003c\/h3\u003e\n\u003cp\u003eFor anyone with a low-noise, high-gain phono stage who wants that last bit of openness. Plain talk: on a normal MM input it'll be too quiet – then the High Output version with 4.0 mV is the right choice.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe Master3 is high-end analogue sound just below the Timbre summit: wood, boron and craftsmanship from Brooklyn. On a good phono stage, the Low Output version extracts that last bit of openness.\u003c\/p\u003e\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Moving Iron phono cartridge (MI), Low Output, stylus replaceable\u003c\/li\u003e\n\u003cli\u003eSeries: Grado Timbre\u003c\/li\u003e\n\u003cli\u003eBody: Australian Jarrah wood\u003c\/li\u003e\n\u003cli\u003eCantilever: Machine-crafted boron, five-piece OTL construction\u003c\/li\u003e\n\u003cli\u003eDiamond: Grado's own, bare elliptical\u003c\/li\u003e\n\u003cli\u003eOutput voltage: 1.0 mV (5 cm\/s)\u003c\/li\u003e\n\u003cli\u003eInductance: 6 mH\u003c\/li\u003e\n\u003cli\u003eResistance: 70 Ω\u003c\/li\u003e\n\u003cli\u003eRecommended load: 10–47 kΩ\u003c\/li\u003e\n\u003cli\u003eFrequency response: 10–60,000 Hz\u003c\/li\u003e\n\u003cli\u003eChannel separation: approx. 30 dB (10–30 kHz)\u003c\/li\u003e\n\u003cli\u003eCompliance: 20 µm\/mN\u003c\/li\u003e\n\u003cli\u003eRecommended tracking force: 1.6–1.9 g\u003c\/li\u003e\n\u003cli\u003eWeight: 10 g\u003c\/li\u003e\n\u003cli\u003eManufacturing: Hand-assembled in Brooklyn, NY\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eLow or High Output – which version?\u003c\/h3\u003e\n\u003cp\u003eThis Low Output version (1.0 mV) has fewer windings but thicker wire and a shorter signal path – this can sound especially open and clean, but requires a low-noise phono stage with more gain. If you're using a normal MM input, you're better served by the High Output version (4.0 mV).\u003c\/p\u003e\n\u003ch3\u003eIs the Master3 MM or MC?\u003c\/h3\u003e\n\u003cp\u003eTechnically a Moving Iron system. This version works at 1.0 mV on a low-noise phono stage (10–47 kΩ load) and isn't sensitive to cable capacitance – unlike many classic MM systems.\u003c\/p\u003e\n\u003ch3\u003eWhere does the Master3 rank in the Timbre series?\u003c\/h3\u003e\n\u003cp\u003eIn ascending order: Opus3 (maple), Platinum3 and Sonata3 (Jarrah, aluminium cantilever), then Master3 and Reference3 (Jarrah, boron cantilever).
