Its presentation is balanced and controlled, with clear detail and a smooth, natural top end, a midrange with presence and body, and low frequencies that are defined and well structured. Recordings are reproduced with stability, coherence, separation, and imaging without exaggeration, letting the recording itself define the listening experience. The Master4 is available now at Vinyl Sound in Canada.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cp\u003eThe Master4 pairs a nude elliptical diamond with a machined boron cantilever, prized for its low mass and responsive behaviour, contributing speed, stability, and a controlled, natural presentation. It is housed in an American Osage wood body chosen to help control resonance and shape tonal balance, with a reshaped housing that improves cantilever visibility for precise alignment across a wide range of tonearms. Like all Grado cartridges it uses Joseph Grado's patented flux-bridger moving iron principle, and runs an internal signal path of ultra-high-purity 6N OCC copper with cryogenic treatment and internal damping to reduce resonance and preserve signal integrity.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCartridge Type\u003c\/td\u003e\n\u003ctd\u003eMoving iron, high or low output\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eHousing\u003c\/td\u003e\n\u003ctd\u003eAmerican Osage wood body\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStylus\u003c\/td\u003e\n\u003ctd\u003eNude elliptical diamond\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCantilever\u003c\/td\u003e\n\u003ctd\u003eMachined boron\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Principle\u003c\/td\u003e\n\u003ctd\u003eGrado flux-bridger moving iron\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInternal Wiring\u003c\/td\u003e\n\u003ctd\u003e6N OCC ultra-high-purity copper\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTreatment\u003c\/td\u003e\n\u003ctd\u003eCryogenic treatment and internal damping\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Options\u003c\/td\u003e\n\u003ctd\u003eHigh output and low output\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWood Cartridge Upgrade Program\u003c\/h3\u003e\n\u003cp\u003eAs a Grado wood body cartridge, the Master4 is supported by Grado's Wood Cartridge Upgrade Program, which lets you move from a current Grado wood cartridge to another model with a pricing accommodation.
