{"product_id":"naim-nap-500-dr","title":"Naim NAP 500 DR","description":"Our design brief for the NAP 500 required an amplifier that could drive any load down to 2 Ohms for prolonged periods, deliver over 100W into 8 Ohms and sound - at the very least - as good as our reference at the time, the NAP135.\u003cbr\u003e\u003cbr\u003eNaim has always understood the importance of reducing supply-induced intermodulation distortions and mains harmonic electrical noise from an amplifier, and has always used regulated supplies in its premier amplifiers. It was considered likely that improvements in these areas would yield further large gains in performance. Each channel of the NAP 500 includes ten stages of local regulation. To reduce interference from the mains supply further, the transformer and first stages of the power supply are in a separate enclosure (the same size as a Supercap), which provides twelve raw d.c. supplies for the power amplifier. Hence, the NAP 500 system consists of two boxes, a stereo amplifier and a separate power supply.\u003cbr\u003e\u003cbr\u003eThe performance of the finished amplifier exceeds the design brief in all areas. Power output per channel is over 140W into 8 ohms and compared with the NAP 135, which in itself already provided exemplary measurements, the NAP 500 has five times the internal bandwidth, a quarter of the distortion and a one hundred times reduced operating noise floor.\u003cbr\u003e\u003cbr\u003eNeedless to say, every aspect of the NAP 500's sound quality is truly exceptional.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eSpecifications\u003cbr\u003ePower output continuous [8 Ohm] 140 Watts\u003cbr\u003eVoltage gain + 29 dB\u003cbr\u003eInput impedance 18 kOhm\u003cbr\u003eFrequency response -3dB @ 1.5Hz \u0026amp; 100kHz\u003cbr\u003eNAP 500 dimensions (H x W x D) 160 x 432 x 374mm\u003cbr\u003ePower supply dimensions (H x W x D) 87x 432 x 314mm\u003cbr\u003eFinish Black","brand":"Naim Audio","offers":[{"title":"Default Title","offer_id":57407194038604,"sku":"NAIMNAP500","price":18332.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/naimnap500.jpg?v=1777455381","url":"https:\/\/www.stoneaudio.co.uk\/products\/naim-nap-500-dr","provider":"Stone Audio","version":"1.0","type":"link"}
