LP International Product of the Year 2025\/26.\u003c\/h2\u003e\n\u003cp\u003eThe Mandolin is the cartridge that introduced OTTA to the analog audio world, and won the LP International Product of the Year award doing it. It is a moving-coil cartridge designed in Germany by Eckhard Derks, voiced to put the midrange — the band where the human voice lives, where strings breathe, where a piano's body resonates — at the center of everything else the cartridge does. It is the natural step up from a serious mass-market MC into hand-built territory, in a voice that does not sound Japanese.\u003c\/p\u003e\n\u003ch2\u003eDesign notes\u003c\/h2\u003e\n\u003cp\u003eThe Mandolin is built around a samarium-cobalt motor with a deliberately enlarged magnetic gap and gold-plated pure-iron yokes. The point of the enlarged gap is mechanical — it lets the coil move through a more uniform field, which is the unromantic engineering choice that translates into low intermodulation distortion in the midrange. The coil is a cross-coil geometry wound by hand from certified 6N OCC pure-iron-equivalent wire, with tolerances tight enough that each finished cartridge measures within OTTA's published channel-balance window.\u003c\/p\u003e\n\u003cp\u003eThe cantilever is \u003cstrong\u003eruby\u003c\/strong\u003e — not boron, not aluminum. Ruby is harder than either, and at this scale it is also lighter for its stiffness, which gives the cantilever fast transient recovery without the brittleness ruby gets a reputation for in larger structures. The stylus is a refined elliptical diamond, profiled for accurate groove tracking without the setup-sensitivity of a fine-line cut. The body is CNC-machined black sandalwood enclosing an aluminum motor frame — the sandalwood is naturally air-dried and chosen for its damping behaviour.\u003c\/p\u003e\n\u003cp\u003eEach cartridge is wound, assembled, and measured by technicians with more than twenty-five years of experience in the trade, and is individually QC'd on a real tonearm before it ships.\u003c\/p\u003e\n\u003ch2\u003eHow it sounds\u003c\/h2\u003e\n\u003cp\u003eOTTA's own description of the voicing — and the LP International review's — converge on the same words: \u003cem\u003ecreamy, juicy, emotionally present.\u003c\/em\u003e Holger Barske at LP International called the Mandolin \"incredibly emotional and juicy\" and noted that even sparse, restrained jazz takes on \"life and drive.\" That is the design target made audible. The Mandolin is not a hyper-detail cartridge and is not trying to be — it is a cartridge that gives voices their weight, strings their air, and a small group its sense of being in the room. It is, in other words, a midrange-first MC for people who came to vinyl for the music.\u003c\/p\u003e\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Moving Coil (MC), stereo\u003c\/li\u003e\n\u003cli\u003eOutput: 0.35 mV\u003c\/li\u003e\n\u003cli\u003eInternal impedance: 5 Ω\u003c\/li\u003e\n\u003cli\u003eRecommended load: 100–470 Ω\u003c\/li\u003e\n\u003cli\u003eDynamic compliance: 15 µm\/mN\u003c\/li\u003e\n\u003cli\u003eTracking force: 1.5–2.0 g (1.8 g recommended)\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20 Hz – 25 kHz (±3 dB)\u003c\/li\u003e\n\u003cli\u003eChannel balance: \u0026lt; 0.8 dB\u003c\/li\u003e\n\u003cli\u003eChannel separation: \u0026gt; 26 dB\u003c\/li\u003e\n\u003cli\u003eCantilever: Ruby\u003c\/li\u003e\n\u003cli\u003eStylus: Refined elliptical diamond\u003c\/li\u003e\n\u003cli\u003eBody: Black sandalwood (CNC, aluminum motor frame)\u003c\/li\u003e\n\u003cli\u003eWeight: 8.4 g\u003c\/li\u003e\n\u003cli\u003eRecommended arm mass: Medium\u003c\/li\u003e\n\u003cli\u003eBreak-in: 40 hours\u003c\/li\u003e\n\u003cli\u003eDL-103-compatible mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePairing \u0026amp; setup\u003c\/h2\u003e\n\u003cp\u003eThe Mandolin wants a medium-mass arm (effective mass roughly 8–14 g) and a phono stage with at least 60 dB MC gain. Loading is forgiving across the 100–470 Ω window — most modern MC phono stages will land somewhere in that band. Because the Mandolin shares the Denon DL-103 mounting footprint, it drops cleanly into virtually any headshell or arm that has carried a 103 before — a real convenience for the analog veteran with an existing setup.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003ca href=\"\/pages\/contact\"\u003eContact Alma\u003c\/a\u003e to arrange a showroom appointment.\u003c\/em\u003e\u003c\/p\u003e","brand":"OTTA","offers":[{"title":"Default Title","offer_id":48789016805595,"sku":null,"price":2500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1363\/6553\/files\/otta-front_8601ce64-1fc6-4a5d-9470-273dd48f46a8.avif?v=1779199719","url":"https:\/\/almaaudio.com\/products\/otta-mandolin","provider":"Alma Music and Audio","version":"1.0","type":"link"}
