{"product_id":"gradored3","title":"Grado Prestige Red3 MI Phono Cartridge","description":"\u003cp\u003eThe Grado Prestige Red3 is a Moving Iron phono cartridge from the Prestige series, hand-assembled in Brooklyn – with high output voltage for any MM phono input. Within the Prestige lineup, it sits between the Green3 and Gold3.\u003c\/p\u003e\n\u003cp\u003eA versatile all-rounder: detailed and clear, without weakening in any particular discipline – a good first proper cartridge and a sensible upgrade for entry-level turntables.\u003c\/p\u003e\n\u003ch2\u003eWhy the Red3?\u003c\/h2\u003e\n\u003cp\u003eGrado builds its cartridges on the Moving Iron principle – instead of a magnet or a coil, a tiny iron piece moves. This keeps the inductance roughly ten times lower than in classic MM systems and produces a clean, open treble.\u003c\/p\u003e\n\u003cp\u003eCompared to the Green3, the Red3 uses a four-piece OTL cantilever (Optimized Transmission Line) with a Grado-own diamond on a brass bushing – this transmits the groove signal with even less loss and suppresses resonances. A dual-magnet system and ultra-pure copper coils ensure precise channel balance.\u003c\/p\u003e\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eThe typical Grado character with an extra dose of detail and clarity: full, lively and spacious, while still versatile enough for almost any system. Recommended tracking force 1.5 g.\u003c\/p\u003e\n\u003ch3\u003eWho is the Red3 for?\u003c\/h3\u003e\n\u003cp\u003eFor anyone with an MM phono input who wants more than the entry level offers, but doesn't want to jump straight to the top model. Plain talk: if you have a pure MC input with no MM option, you're better served by a moving-coil system – the Red3 wants to see a 47 kΩ MM input.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe Red3 is the golden middle of the Prestige series: more resolution than the entry level, uncomplicated in operation and a cartridge that grows with your system.\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 Prestige (mid-range)\u003c\/li\u003e\n\u003cli\u003eFrequency response: 10–50,000 Hz\u003c\/li\u003e\n\u003cli\u003eOutput voltage: 5 mV (1 kHz, 5 cm\/s)\u003c\/li\u003e\n\u003cli\u003eRecommended load: 47 kΩ\u003c\/li\u003e\n\u003cli\u003eRecommended tracking force: 1.5 g\u003c\/li\u003e\n\u003cli\u003eCantilever: Four-piece OTL construction\u003c\/li\u003e\n\u003cli\u003eDiamond: Grado's own, on a brass bushing\u003c\/li\u003e\n\u003cli\u003eMagnet system: Dual magnet, ultra-pure copper coils\u003c\/li\u003e\n\u003cli\u003eMounting: Standard 1\/2 inch\u003c\/li\u003e\n\u003cli\u003eWeight: approx. 5.5 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\u003eWhat's the difference between Red3, Green3 and Gold3?\u003c\/h3\u003e\n\u003cp\u003eAll three are Moving Iron systems in the Prestige series with 5 mV and 47 kΩ. The Green3 is the entry point (three-piece OTL cantilever). The Red3 uses a four-piece cantilever and sits in the middle. The Gold3 is hand-selected and additionally uses a finely finished generator for more transparency.\u003c\/p\u003e\n\u003ch3\u003eIs the Red3 an MM or MC system?\u003c\/h3\u003e\n\u003cp\u003eTechnically it's a Moving Iron system, but it's operated like an MM: high output voltage (5 mV), 47 kΩ load, connects to any MM phono input. The stylus is user-replaceable – so a later stylus change remains simple.\u003c\/p\u003e\n\u003ch3\u003eWhy buy the Grado Red3 at HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause a cartridge only shows its potential with correct setup.
