An amplifier is the workhorse of any system. It is responsible for receiving small signals from a preamplifier or source component, and developing them into larger currents to control a loudspeaker. To that end, the GS150 has been designed to seamlessly integrate into any system and steadfastly perform its task. Challenging source material and difficult speaker loads are met with control and finesse to present a musical landscape of breathtaking proportions.About this unit
Fantastic condition store demo Audio Research GS150 amplifier. Unit has a silver faceplate, silver sides, a black body, and black handles. Unit comes in original box and packaging with owner’s manual, and power cord.
Unit is rated 8/10 for light use and minor cosmetic wear consistent with use, including a few minor nicks/scuffs visible only from the back of the unit (see photos).SpecificationsPOWER OUTPUT
155 watts per channel continuous from20Hz to 20kHz. 1kHz total harmonic distortion typically 0.6% at 155 watts, below 0.03% at 1 watt.Approximate actual power available at ‘clipping’ 160 watts (1kHz). (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 very critical.)
(-3dB points) 5Hz to 80kHz.
(-3dB points at 1 watt) 0.5Hz to 120 kHz
2.0V RMS BAL for rated output. (24 dB Bal gain into 8 ohms.)
