This High Output version delivers 4.0 mV for any MM phono input.\u003c\/p\u003e\n\u003cp\u003eIt brings technology and manufacturing know-how from the more expensive Grado models at an affordable price – the ideal first step into higher-quality analogue sound.\u003c\/p\u003e\n\u003ch2\u003eWhy the Opus3?\u003c\/h2\u003e\n\u003cp\u003eGrado builds on the Moving Iron principle with a dual-magnet system: small moving mass, low inductance, open sound. The maple body – the same tonewood used in Grado's Heritage and Statement headphones – is thermally aged to dampen resonances.\u003c\/p\u003e\n\u003cp\u003eThe aluminium cantilever (modified four-piece OTL construction) is hand-fitted with an elliptical diamond. A new two-stage shielding process and ultra-pure UHPLC copper coils ensure a clean signal path and low mechanical noise.\u003c\/p\u003e\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eThe typical, slightly warm Grado character with clear, effortless reproduction across the whole frequency range – without harshness. An excellent all-rounder for pop, rock and acoustic music.\u003c\/p\u003e\n\u003ch3\u003eWho is the Opus3 for?\u003c\/h3\u003e\n\u003cp\u003eFor anyone with an MM phono input who wants to give their turntable its first proper step towards high end. Plain talk: if you already have a very fine turntable and a good phono stage, you'll get more enjoyment from a Platinum3 or Sonata3.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe Opus3 is the most affordable way into Grado's wood-bodied cartridges: musical, versatile and honestly made. A splendid starting point – and a clear upgrade for any entry-level turntable.\u003c\/p\u003e\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Moving Iron phono cartridge (MI), High Output, stylus replaceable\u003c\/li\u003e\n\u003cli\u003eSeries: Grado Timbre (entry level)\u003c\/li\u003e\n\u003cli\u003eBody: Maple wood\u003c\/li\u003e\n\u003cli\u003eCantilever: Aluminium, modified four-piece OTL construction\u003c\/li\u003e\n\u003cli\u003eDiamond: Elliptical\u003c\/li\u003e\n\u003cli\u003eOutput voltage: 4.0 mV (5 cm\/s)\u003c\/li\u003e\n\u003cli\u003eInductance: 55 mH\u003c\/li\u003e\n\u003cli\u003eResistance: 660 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: 8 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\u003eHigh or Low Output – which version?\u003c\/h3\u003e\n\u003cp\u003eThis High Output version (4.0 mV) fits any classic MM phono input and is the right choice for most systems. The Low Output version (1.0 mV) can potentially sound even more open on a low-noise phono stage but requires significantly more gain.\u003c\/p\u003e\n\u003ch3\u003eIs the Opus3 MM or MC?\u003c\/h3\u003e\n\u003cp\u003eTechnically a Moving Iron system, operated like an MM: 4.0 mV output, 10–47 kΩ load, on any MM input. Not sensitive to cable capacitance.
