{"product_id":"audio-research-reference-phono-10-phono-stage","title":"Audio Research Reference Phono 10 Phono Stage","description":"\u003cp\u003eThe Reference Phono 10 is Audio Research's ultimate phono stage, a true dual-mono design across separate amplification and power supply chassis, with independent signal paths, separate high- and low-voltage transformers per channel, and twenty stages of electronic regulation including separate vacuum-tube regulation for each channel. The fully discrete, pure Class-A, zero-feedback audio circuit uses eight 6H30 tubes, with high-gain, extremely low-noise FETs in place of a step-up transformer. Two independently configurable inputs offer switchable gain, seven loading options and selectable RIAA, Columbia and Decca equalization, all accessible by remote control.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eConfiguration\u003c\/th\u003e\n\u003ctd\u003eTwo-chassis, true dual mono\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eEqualization\u003c\/th\u003e\n\u003ctd\u003eSelectable RIAA, Columbia, Decca\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\u003eWithin 0.2dB of RIAA, 10Hz to 60kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eGain\u003c\/th\u003e\n\u003ctd\u003eSelectable 51dB (low) or 74dB (high) balanced at 1kHz, MC and MM compatible\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eLoading\u003c\/th\u003e\n\u003ctd\u003eSelectable 1000, 500, 200, 100, 50 ohms and Custom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eTopology\u003c\/th\u003e\n\u003ctd\u003eFully balanced, pure Class A, zero feedback\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eTube complement\u003c\/th\u003e\n\u003ctd\u003eEight 6H30P dual triodes, plus two each 6550C and 6H30P in power supply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eOptions \u0026amp; Upgrades\u003c\/h3\u003e\u003ctable\u003e\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em;font-weight:400\"\u003eDiscrete mono input\u003cbr\u003e\u003csmall\u003eDedicated mono input option, Reference Phono 10 only\u003c\/small\u003e\n\u003c\/th\u003e\n\u003ctd style=\"white-space:nowrap\"\u003e+$1,500\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/table\u003e\u003cp\u003e\u003csmall\u003ePrices shown are for the base configuration.
