{"product_id":"audio-research-reference-160s-stereo-power-amplifier","title":"Audio Research Reference 160S Stereo Power Amplifier","description":"\u003cp\u003eThe Reference 160S stereo power amplifier brings the award-winning performance and design of the REF160M monoblocks into a single chassis. Featuring eight KT150 output tubes, dual GhostMeters™, proprietary auto-bias, switchable Triode and Ultralinear modes, balanced and single-ended inputs and output tube monitoring, it combines advanced functionality with striking aesthetics. Its four-layer circuit board helps deliver exceptional clarity, dynamic impact and low-noise performance from a jet-black background. Weighing 100 pounds, the REF160S captures the musical purity, resolution and finesse of the REF160M in a more accessible stereo design built for serious music lovers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Output: \u003c\/strong\u003e140 watts continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 140 watts, below 0.04% at 1 watt. (Note that actual power output is dependent upon both line voltage and “condition” i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not critical)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Bandwidth:\u003c\/strong\u003e (-3dB Points) 5Hz to 70kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response: \u003c\/strong\u003e(-3dB points at 1 watt) 0.5Hz to 110kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Sensitivity:\u003c\/strong\u003e 2.4V RMS Balanced for rated output.
