{"product_id":"nuprime-evolution-sta-se","title":"NuPrime Evolution STA-SE – Stereo Power Amplifier","description":"\u003cp\u003eNuPrime Evolution STA-SE is a reference-class stereo power amplifier delivering 2 x 400 W into both 8 and 4 ohms. A dual-mono design with independent power paths for each channel provides minimal crosstalk and maximum focus in the soundstage.\u003c\/p\u003e\n\u003cp\u003eAt its core is NuPrime’s ODC technology (Only Distortion Cancellation), a Class D design that extracts the error signal directly from the MOSFET circuits and output filter instead of using a global feedback loop. The result is distortion of 0.002% THD+N and completely neutral, transparent reproduction. The 650 kHz switching frequency provides resolution approaching that of the finest analog designs.\u003c\/p\u003e\n\u003cp\u003eThe power supply is based on GaN semiconductors (gallium nitride) with active noise reduction, which counteracts interference on the mains voltage in real time—the same principle used in noise-cancelling headphones. The power section handles 40 A of current with 52,000 µF filter capacitors, while the RCA inputs are Furutech FP900 and the speaker terminals are high-conductivity types. The result is an amplifier with Class A-like warmth in the midrange and the power of a transistor amplifier, without the heat or weight of either.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOutput power (RMS): 2 x 400 W at 8 ohms and 4 ohms\u003c\/li\u003e\n\u003cli\u003eGain: x21\u003c\/li\u003e\n\u003cli\u003eSensitivity: 2 Vrms\u003c\/li\u003e\n\u003cli\u003eInput impedance: 47 kohms\u003c\/li\u003e\n\u003cli\u003eOutput impedance: 4 mohm\u003c\/li\u003e\n\u003cli\u003eTHD+N: 0.0025% at 5W, 0.007% at 50W, 0.01% at 100W\u003c\/li\u003e\n\u003cli\u003eSignal-to-noise ratio: 95 dB at 5W, 105 dB at 50W, 110 dB at 100W\u003c\/li\u003e\n\u003cli\u003eFrequency response: 10 Hz to 50 kHz (-3 dB)\u003c\/li\u003e\n\u003cli\u003eSwitching frequency: 650 kHz\u003c\/li\u003e\n\u003cli\u003eConnections: Furutech FP900 RCA inputs, Eichmann speaker terminals, trigger in\/out\u003c\/li\u003e\n\u003cli\u003eStandby: 1.5 W at 115V, 1.7 W at 230V\u003c\/li\u003e\n\u003cli\u003eMains voltage: 115VAC \/ 230VAC with switch\u003c\/li\u003e\n\u003cli\u003eFuse: slow-blow 7A, 250VAC\u003c\/li\u003e\n\u003cli\u003eDimensions (HxWxD): 57 x 430 x 375 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 9 kg\u003c\/li\u003e\n\u003cli\u003eWarranty: 3 years\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NuPrime","offers":[{"title":"Black","offer_id":53796336337234,"sku":"537963363372","price":66490.0,"currency_code":"SEK","in_stock":true},{"title":"Silver","offer_id":53796336370002,"sku":"537963363700","price":66490.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/9454\/6667\/files\/NuPrime_Evolution_STA-SE__02.jpg?v=1781866497","url":"https:\/\/maxxteknik.com\/en\/products\/nuprime-evolution-sta-se","provider":"Maxxteknik","version":"1.0","type":"link"}
