Audio Research GS150 Amplifier, Factory Refurbished [Expired]


no longer for sale


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.

Three meters across the front panel provide a window into the operation of the amplifier and give the amplifier a striking façade. The selection of premium parts internally is reflected in the beautiful metalwork of the chassis and exquisite finishes. The circuit features the new KT150 power output tubes for 150 watts of effortless power delivery. A reflection of the past yet clearly a guiding light into the future of music reproduction, the GS150 is poised to deliver years of musical enjoyment.
