{"product_id":"ortofon-spu-gtx-e-mc-tonabnehmer","title":"Ortofon SPU GTX E MC Cartridge","description":"\u003cp\u003eThe Ortofon SPU GTX E is a moving-coil cartridge in the classic SPU format with a built-in transformer and an elliptical stylus.\u003c\/p\u003e\n\u003cp\u003eThe SPU design dates back to the 1950s and lives on today because it solves a problem MC cartridges otherwise have: the need for a step-up transformer. On the GTX E, it sits right inside the housing — plug into the tonearm cable, done.\u003c\/p\u003e\n\u003ch2\u003eWhy the SPU GTX E?\u003c\/h2\u003e\n\u003cp\u003eWith 4 mV output voltage, the GTX E behaves on any MM phono input like a high-resolution MM cartridge — no separate transformer, no extra cabling. The heavy housing, cast in fiberglass composite, damps resonances and gives the presentation a rich, grounded character instead of a bright, analytical one.\u003c\/p\u003e\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eThe typical SPU character: powerful, warmly voiced, with a midrange that gives substance to voices and brass. Not the ultimate resolver, but a cartridge that lets you listen relaxed for hours and reproduces jazz and classical recordings with pleasant physicality.\u003c\/p\u003e\n\u003ch3\u003eWho is the SPU GTX E suited for?\u003c\/h3\u003e\n\u003cp\u003eFor listeners with an SPU-compatible tonearm (medium-weight to heavy, universal bayonet connector) who want the analog SPU sound without having to buy an extra transformer. Straight talk: anyone after maximum detail resolution is better served by the nude styli of the Cadenza or Windfeld series — the GTX E deliberately plays musical rather than analytical.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe pragmatic entry into SPU sound: built-in transformer, elliptical stylus, rich sound. If you want an SPU but don't want to buy an extra transformer, this is the one.\u003c\/p\u003e\n\u003ch2\u003eTechnical data\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: MC cartridge with built-in transformer (SPU design)\u003c\/li\u003e\n\u003cli\u003eStylus: elliptical, r\/R 8\/18 µm\u003c\/li\u003e\n\u003cli\u003eOutput voltage (1 kHz, 5 cm\/s): 4 mV\u003c\/li\u003e\n\u003cli\u003eInternal impedance (DC): 610 ohms\u003c\/li\u003e\n\u003cli\u003eRecommended load impedance: 47 kOhm, 150–600 pF\u003c\/li\u003e\n\u003cli\u003eChannel separation (1 kHz): 20 dB\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20–20,000 Hz (±3 dB)\u003c\/li\u003e\n\u003cli\u003eTracking force: 4.0 g\u003c\/li\u003e\n\u003cli\u003eTracking angle: 20°\u003c\/li\u003e\n\u003cli\u003eCoil wire: OFC (oxygen-free copper)\u003c\/li\u003e\n\u003cli\u003eHousing: fiberglass-reinforced plastic with built-in transformer\u003c\/li\u003e\n\u003cli\u003eWeight: 38 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eDo I need a separate transformer for the SPU GTX E?\u003c\/h3\u003e\n\u003cp\u003eNo. The transformer is already inside the housing, so a normal MM phono input is enough. That's the whole point of the GTX E compared to classic SPU cartridges without a built-in transformer.\u003c\/p\u003e\n\u003ch3\u003eWhich tonearm suits the SPU GTX E?\u003c\/h3\u003e\n\u003cp\u003eA medium-weight to heavy tonearm with a universal SPU\/bayonet connector, such as classic Ortofon, EMT, or Jelco tonearms offer.
