{"product_id":"audio-research-reference-10-line-stage-preamplifier","title":"Audio Research Reference 10 Line-Stage Preamplifier","description":"\u003cp\u003eAudio Research has long set benchmarks in preamplifier design, from the SP3 (1973) to the limited-edition Reference Anniversary (2010). Building on continued innovation, the Reference 10 line stage represents its most advanced design yet. It delivers lifelike scale, deep and controlled bass, and exceptional clarity, revealing fine details and spatial cues in recordings. The sound is natural, dynamic, and highly refined, enhancing both large ensembles and subtle nuances. Its dual-chassis design includes a dedicated power supply. With premium materials and craftsmanship, the Reference 10 offers a significant leap in performance, creating a more immersive and authentic listening experience.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e +0 -3dB 0.1Hz to 200kHz at rated output.\u003cbr\u003e(BALANCED, 200k ohms load.)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDistortion:\u003c\/strong\u003e Less than .006% at 2V RMS Balanced output\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGain:\u003c\/strong\u003e Main output (SE or BAL input)12dB Balanced output,\u003cbr\u003e6dB Single Ended output.
