Thanks to its dual-mono design, with completely separate power paths for each channel, crosstalk is kept low and the focus of the soundstage remains precise.\u003c\/p\u003e\n\u003cp\u003eAt the heart of the design is NuPrime’s ODC technology (Only Distortion Cancellation), a Class D solution that extracts the error signal directly from the MOSFET circuits and output filter instead of using a global feedback loop. This results in 0.002% THD+N and completely neutral, transparent reproduction. With a switching frequency of 650 kHz, its resolution approaches that of the very best analogue designs.\u003c\/p\u003e\n\u003cp\u003eThe power supply uses GaN semiconductors (gallium nitride) with active noise reduction, continuously counteracting interference in the mains voltage—much like noise-cancelling headphones, but on the power side. The power section handles 40 A with 52,000 uF filter capacitors, while the rear panel features Furutech FP900 RCA inputs and highly conductive speaker terminals. The result is an amplifier with Class A warmth in the midrange and the power of a transistor amplifier, without bringing along 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":57153145504068,"sku":"571531455040","price":66490.0,"currency_code":"SEK","in_stock":true},{"title":"Silver","offer_id":57153145536836,"sku":"571531455368","price":66490.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0919\/1306\/0676\/files\/NuPrime_Evolution_STA-SE__02.jpg?v=1787753771","url":"https:\/\/www.mychifi.se\/en\/products\/nuprime-evolution-sta-se-stereoslutsteg","provider":"MYC HiFi","version":"1.0","type":"link"}
