{"product_id":"moonriver-audio-model-404-integrated-amplifier","title":"Moonriver Audio Model 404 Integrated Amplifier","description":"\u003cp\u003eThe Model 404 is Moonriver Audio's Swedish-built integrated amplifier, the outcome of three years of research and hand-assembled in Sweden. It pairs a fully discrete preamp section with a dual-mono power stage fed by five separate power supplies, delivering 50 watts per channel into 8 ohms, with volume attenuation handled by the blue ALPS potentiometer. Its modular architecture accepts an optional MM or MM\/MC phono stage and an optional DAC module, while classic touches such as balance control, a stereo\/mono switch and a tape monitor loop are retained by design. The chassis pairs massive aluminium knobs with solid walnut cheeks, and through-hole components are used throughout the analog circuits.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003ePower output\u003c\/th\u003e\n\u003ctd\u003e50 W per channel into 8 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eFrequency response\u003c\/th\u003e\n\u003ctd\u003e10 Hz to 50 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eTotal harmonic distortion\u003c\/th\u003e\n\u003ctd\u003e0.05%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eSignal-to-noise ratio\u003c\/th\u003e\n\u003ctd\u003e85 dB (line)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eInputs\u003c\/th\u003e\n\u003ctd\u003e5 (line 1 and 4 optionally occupied by phono stage and USB DAC, 1 x tape loop)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e430 (W) x 390 (D) x 135 (H) mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e12 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eOptions \u0026amp; Upgrades\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em;font-weight:400\"\u003ePhono stage module, MM\u003cbr\u003e\u003csmall\u003eFactory-fitted moving magnet phono input\u003c\/small\u003e\n\u003c\/th\u003e\n\u003ctd style=\"white-space:nowrap\"\u003e+$689\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em;font-weight:400\"\u003ePhono stage module, MC\/MM\u003cbr\u003e\u003csmall\u003eFactory-fitted moving coil \/ moving magnet phono input\u003c\/small\u003e\n\u003c\/th\u003e\n\u003ctd style=\"white-space:nowrap\"\u003e+$849\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em;font-weight:400\"\u003eSPDIF DAC module\u003cbr\u003e\u003csmall\u003eDSD and MQA support, up to 24-bit\/192kHz\u003c\/small\u003e\n\u003c\/th\u003e\n\u003ctd style=\"white-space:nowrap\"\u003e+$999\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003e\u003csmall\u003ePrices shown are for the base configuration.
