{"product_id":"moonriver-audio-model-404-reference-integrated-amplifier","title":"Moonriver Audio Model 404 Reference Integrated Amplifier","description":"\u003cp\u003eThe Model 404 Reference builds on the design platform of the standard Model 404, with the power supply section improved to the maximum. Total capacitance rises from 57,000 uF to 107,000 uF, of which 21,000 uF is reserved for the preamp alone, and WBT nextgen speaker terminals carry the output stage's current to even difficult-to-drive loudspeakers. The chassis adds absorbent materials and better integral mechanical support to further reduce resonant vibration, while the fully discrete preamp, dual-mono power amplifier, balance control, stereo\/mono switch and tape monitor loop carry over. It holds a place in Stereophile's Class A Recommended Components and accepts the same optional phono stage and DAC modules as its sibling.\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\"\u003ePower supply capacitance\u003c\/th\u003e\n\u003ctd\u003e107,000 uF total (21,000 uF reserved for the preamp)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eSpeaker terminals\u003c\/th\u003e\n\u003ctd\u003eWBT nextgen\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\u003e13 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.
