{"product_id":"audio-research-s-100-stereo-power-amplifier","title":"Audio Research S-100 Stereo Power Amplifier","description":"\u003cp\u003eThe S-100 solid-state amplifier was designed to deliver the musical engagement and purity traditionally associated with Audio Research’s Reference tube amplifiers. Featuring a fully balanced dual-mono Class A\/B design with dual toroidal transformers it offers strong dynamics and doubles its power into 4-ohm loads. Bipolar transistors were selected for their transparency and natural sound quality. Housed in a sleek machined aluminum chassis with modernized Audio Research styling the S-100 combines refined aesthetics with advanced engineering. Built and voiced by ear in Minnesota alongside the company’s flagship tube products it emphasizes musicality as much as technical performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Output:\u003c\/strong\u003e 100 Watts channel into 8 ohms ; 200 Watts channel into 4 ohms\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTHD:\u003c\/strong\u003e \u0026lt;.1% from 0.25W to rated output into 8 ohms @ 1Khz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Sensitivity:\u003c\/strong\u003e 1.4V RMS Balanced for rated output\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance: \u003c\/strong\u003e100kΩ Balanced or Single-Ended\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGain: \u003c\/strong\u003e26dB\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Sensitivity:\u003c\/strong\u003e 1.8VRMS for rated output\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNoise:\u003c\/strong\u003e \u0026lt;60µV output\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e +\/- 0.1db from 20Hz to 20KHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDamping Factor:\u003c\/strong\u003e ?? from 20Hz to 1KHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Requirements:\u003c\/strong\u003e @120VAC ; Standby: 0.25W.
