NuPrime has been advancing Class-D amp performance over the last decade, and the innovative ODC approach takes its amplifiers to the highest level of achievement.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe Evolution STA gives your music a wide and deep soundstage with no loss of clarity at the greatest depth. The natural and pure presentation is distinguished by a clean background and Class A-like warmth. The STA offers substantial muscle for hi-fi or home theater, providing rated RMS power of 230 watts at 8 ohms and 310 watts at 4 ohms. Peak power output is 270 watts at 8 ohms and 360 watts at 4 ohms.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eBringing your favorite music to life, NuPrime's hybrid Class D technology retains the merits of both Class A and Class D amplification, for warmth, speed, and power. The high-speed 650 kHz switching frequency allows exceptional resolution to be achieved.\u003c\/p\u003e\n\u003ch4\u003eNo-Compromise Power Supply\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe power supply can make or break a power amplifier. NuPrime went all the way with the Evolution STA to support uncompromising sound quality. The custom designed iron core linear power supply has a dual routing for dual outputs, with dual wire per output, to function as two power supplies for dual-mono implementation. High quality copper PCB trace instead of the usual cables connect the power supply to the amplifier’s circuitry, maximizing power delivery.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe 550W high-power ultra-thin toroidal transformer power supply has been enhanced to deliver clean and extremely stable power with a very low noise floor. The entire power path fully supports 40A ultra-high current and low resistance terminals with dynamic current capability. The power supply filter capacitors are rated at total of 52,000uF.\u003c\/p\u003e\n\u003ch4\u003eOnly Distortion Cancellation (ODC) Design\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eDelving deep under the hood, here is a quick summary of NuPrime's breakthrough Only Distortion Cancellation (ODC) Design. A typical feedback error correction design inverts the output signal for summation with the original input signal to derive the negative error signal – which adds to the next cycle of the input signal to form a more accurate output signal.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eNuPrime’s ODC Class-D design has a significant advantage. It derives the error signal from MOSFET devices and the output filter circuit directly, significantly reducing the negative feedback signal. This results in a substantial reduction in distortion, with THD+N of 0.002% at 1 kHz (5W) and less than 0.005% THD+N at 1 kHz (2W-100W). This breakthrough improvement in Class-D design results in a pure and natural audio experience.\u003c\/p\u003e","brand":"NuPrime","offers":[{"title":"New","offer_id":45982006771885,"sku":"NEW-NPEVOSTA-SIL","price":4995.0,"currency_code":"USD","in_stock":false},{"title":"Demo","offer_id":45982006804653,"sku":"DEMO-NPEVOSTA-SIL","price":4299.99,"currency_code":"USD","in_stock":false},{"title":"Open Box","offer_id":45982006837421,"sku":"OPEN-NPEVOSTA-SIL","price":4299.99,"currency_code":"USD","in_stock":false},{"title":"Cosmetically Blemished","offer_id":45982006870189,"sku":"BLEM-NPEVOSTA-SIL","price":4299.99,"currency_code":"USD","in_stock":false},{"title":"Factory Refreshed","offer_id":45982006902957,"sku":"RFRB-NPEVOSTA-SIL","price":4299.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/3708\/1773\/files\/NPEVOSTA_SIL_01-Large__10312.1724172665.1280.1280_ce460de4-14e6-47c4-a7e4-d7cab99968b4.jpg?v=1778103485","url":"https:\/\/www.audioadvisor.com\/products\/nuprime-evolution-sta-stereo-amplifier-silver","provider":"Audio Advisor","version":"1.0","type":"link"}
