{"product_id":"line-magnetic-lm-216ia-vollverstaerker","title":"Line Magnetic LM-216IA Tube Integrated Amplifier","description":"\u003cp\u003eThe Line Magnetic LM-216IA is a push-pull tube integrated amplifier with four KT88 output tubes and 2×38 watts of output power. Line Magnetic builds it by hand in Nanjing, point-to-point wired, with components you'd otherwise expect only in reference-class gear: ALPS potentiometers, Realcap coupling capacitors, a custom-wound toroidal transformer.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the LM-216IA?\u003c\/h2\u003e\n\u003cp\u003eThe LM-216IA is the entry point into this craft – and still no compromise device. If you've always thought \"tube\" inevitably meant expensive and fussy, this will change your mind.\u003c\/p\u003e\n\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eFour KT88s in push-pull deliver a solid 38 watts per channel – enough for most bookshelf speakers and many floorstanders in a living room. The sound is typically tube: warm in the midrange, with a soundstage that renders instruments more like musicians than measurement figures. A bias control with a genuine ammeter on top lets you adjust the tubes yourself – tools included.\u003c\/p\u003e\n\n\u003ch3\u003eWho is the LM-216IA for? (and who it isn't)\u003c\/h3\u003e\n\u003cp\u003eFor listeners looking to get into tube technology for the first time, without putting down several thousand francs right away. Straight talk: if you run highly efficient full-range or horn speakers and want an especially quiet noise floor, take a look at the single-ended models in the range instead – the LM-216IA's push-pull circuit is tuned for power rather than ultimate tube purity.\u003c\/p\u003e\n\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eAn honest entry into genuine tube technology, not a tube dummy with transistor innards. If you've been toying with the idea of trying tube sound for a while, this offers a fair entry price with visible craftsmanship.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCircuit design: tube integrated amplifier, push-pull\u003c\/li\u003e\n\u003cli\u003eOutput power: 2× 38 W (ultralinear), 2× 22 W (triode)\u003c\/li\u003e\n\u003cli\u003eTube complement: 4× KT88, 2× 12AX7, 2× 12BH7\u003c\/li\u003e\n\u003cli\u003eFrequency response: 10 Hz – 50 kHz (-1.5 dB)\u003c\/li\u003e\n\u003cli\u003eTHD: 1% (1 kHz)\u003c\/li\u003e\n\u003cli\u003eSignal-to-noise ratio: 87 dB (A-weighted)\u003c\/li\u003e\n\u003cli\u003eInput sensitivity: 220 mV\u003c\/li\u003e\n\u003cli\u003eInput impedance: 100 kΩ\u003c\/li\u003e\n\u003cli\u003eSpeaker outputs: 4 Ω \/ 8 Ω\u003c\/li\u003e\n\u003cli\u003eInputs: 4× RCA (line)\u003c\/li\u003e\n\u003cli\u003eDimensions (W×H×D): 376 × 192 × 345 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 19.6 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eDoes the LM-216IA need a break-in period?\u003c\/h3\u003e\n\u003cp\u003eYes, like any tube amplifier it benefits from a few hours of operation – the sound and soundstage settle in over the first few days. This is normal and not a sign of a fault.\u003c\/p\u003e\n\u003ch3\u003eCan I connect headphones to the LM-216IA?\u003c\/h3\u003e\n\u003cp\u003eNo, the LM-216IA has no headphone output. For tube sound over headphones, the more compact LM-MINI 84IA from the same range is the better choice.\u003c\/p\u003e\n\u003ch3\u003eDo I have to adjust the tubes myself?\u003c\/h3\u003e\n\u003cp\u003eThe bias can be readjusted by hand via the built-in ammeters on top – a short, one-off task after a tube change, not an ongoing chore.\u003c\/p\u003e\n\u003ch3\u003eWhich speakers suit the LM-216IA?\u003c\/h3\u003e\n\u003cp\u003eSpeakers with a sensitivity of around 88 dB or higher pair best with the 38 watts of output power.
