{"product_id":"emt-jsd-vm-cartridge","title":"EMT JSD VM Cartridge","description":"\u003cp\u003eThe JSD VM is a reference stereo cartridge with a feature no other cartridge in current production offers: a variable-mass body. The listener can tune the cartridge's resonance behaviour to the tonearm — and to personal preference — in the room, without a workbench trip or a re-cartridging.\u003c\/p\u003e\n\n\u003cp\u003eThe mechanism is three interchangeable inlay bolts, each machined from a different material. Fitted in turn, each bolt shifts the cartridge's mass distribution and its interaction with the tonearm — a small change on paper, an audible one at the seat. It gives the listener a level of control over the front-end resonance that has historically belonged to the cartridge-alignment specialist, not the owner.\u003c\/p\u003e\n\n\u003cp\u003eUnderneath the tunable body, the JSD VM is the most current EMT generator among the Reference-tier products. The stylus is an MR HP diamond — multi-radius, high-polish. The cantilever is sapphire — the same single-material discipline EMT has held to when maximum stiffness at minimum mass is the goal. The coil is pure 4N copper. The magnet is AlNiCo, gold-plated. The body — aluminium, in the variable-mass configuration — ships in the range of 10 to 12 grams depending on the inlay fitted.\u003c\/p\u003e\n\n\u003cp\u003eOutput is 1 mV at 5 cm\/s. Coil impedance is 2 × 24 Ω per channel. Recommended load is 200 to 300 ohms. Tracking force is 2.4 grams. Compliance is 12 µm\/mN.\u003c\/p\u003e","brand":"EMT","offers":[{"title":"Default Title","offer_id":48938913464539,"sku":null,"price":6995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1363\/6553\/files\/emt-jsd-vm-1_orig.jpg?v=1783137542","url":"https:\/\/almaaudio.com\/products\/emt-jsd-vm-cartridge","provider":"Alma Music and Audio","version":"1.0","type":"link"}
