{"product_id":"emt-tsd-sph-cartridge","title":"EMT TSD SPH Cartridge","description":"\u003cp\u003eThe TSD SPH is the Tondose stereo cartridge with a 15-micron spherical diamond — the profile that was general practice in stereo cartridge design before 1980, kept in current production for the listener whose collection is anchored in the earlier era of stereo LP.\u003c\/p\u003e\n\n\u003cp\u003eThe rationale is not nostalgia. A spherical stylus tracks the groove modulation an early stereo cutter drew for it — and it does so without the audible mismatch a modern line-contact profile can introduce on grooves that were never cut to be tracked that way. The cantilever is aluminium. The body is the 2020-revision solid-magnesium Tondose.\u003c\/p\u003e\n\n\u003cp\u003eOutput transfer level is 0.21 mV\/cm. Coil impedance is 2 × 24 Ω. Recommended load is 200 to 300 ohms. Tracking force is 2.5 grams. Weight is 17.5 grams. Compliance is 12 µm\/mN. Frequency response is 20 to 20,000 Hz, with the ±2 dB broadcast window from 40 to 12,500 Hz.\u003c\/p\u003e\n\n\u003cp\u003eThree mount options: EMT Standard, INT, X.\u003c\/p\u003e","brand":"EMT","offers":[{"title":"EMT (Standard)","offer_id":48938914578651,"sku":null,"price":2995.0,"currency_code":"USD","in_stock":true},{"title":"INT (Ortofon A compatible)","offer_id":48938914939099,"sku":null,"price":2995.0,"currency_code":"USD","in_stock":true},{"title":"X (SME compatible)","offer_id":48938914971867,"sku":null,"price":2995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1363\/6553\/files\/Tondose-2020-3-2048x1365_5b3d088f-a1e9-422e-9f4e-a900957d3d55.jpg?v=1783137567","url":"https:\/\/almaaudio.com\/products\/emt-tsd-sph-cartridge","provider":"Alma Music and Audio","version":"1.0","type":"link"}
