{"product_id":"audio-research-reference-phono-10","title":"Audio Research Reference Phono 10","description":"\u003cp\u003eThe Reference Phono 10 is Audio Research’s flagship phono preamplifier, designed to deliver extraordinary analog realism and musical immersion. Its fully balanced, dual-mono, pure Class-A design uses separate power supplies and extensive tube regulation for exceptional dynamics, detail and low noise. Eight 6H30 tubes and ultra-low-noise FETs provide remarkable clarity, holographic imaging and lifelike musical presence. Supporting multiple gain settings, cartridge loading options and RIAA, Columbia, and Decca equalization curves, the REF Phono 10 offers extensive flexibility for vinyl enthusiasts. Remote-controlled and engineered without feedback, it sets a new benchmark for high-end analog playback performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e ± .2dB of RIAA, 10Hz to 60kHz; 3dB points below 0.3Hz and above 300kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDistortion:\u003c\/strong\u003e Less than .002% at 1.0V RMS 1kHz output\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGain:\u003c\/strong\u003e Selectable 51dB (Low), 74dB (High) at1kHz BAL; 45dB (Low), 68dB (High) at1kHz SE.
