The Audio Research Reference 160 S Power Amplifier is a masterclass in audio design, blending cutting-edge technology with the time-honored traditions of vacuum-tube amplification. This amplifier continues the legacy of the internationally acclaimed 160M monaural amplifier, offering the same stunning sonic performance in a more attainable stereo format. The Reference 160 S has been meticulously designed for music lovers who appreciate purity, resolution, and dynamic impact in their sound reproduction.

The Reference 160 S Power Amplifier delivers 140 watts of continuous power from 20Hz to 20kHz, providing a wide frequency range that captures every nuance of your music. This amplifier is built with dual GhostMeters™, a signature feature of Audio Research’s Reference series, which offers a visually striking floating meter display. Beyond aesthetics, the 160 S is engineered with auto-bias circuitry to ensure optimal tube performance, even as tubes age or powerline voltage fluctuates.

One of the key features of the 160 S is its Triode or Ultralinear mode switching, giving users the flexibility to tailor the amplifier’s sound based on personal preference or speaker requirements. Whether you’re using it in Triode mode for a warmer, more intimate sound or Ultralinear mode for greater power and dynamic range, this amplifier adapts to your needs seamlessly. The Reference 160 S uses balanced and single-ended inputs for maximum compatibility with various audio systems, and its fully balanced design ensures minimal distortion and ultimate clarity.

Another standout feature is the four-layer circuit board, which allows the amplifier to project music against a jet-black background, making even the finest details of the recording come to life. The sound is projected with astonishing resolution and depth, allowing listeners to feel as if they are in the presence of a live musical performance. The 160 S pairs exceptionally well with high-end speakers from brands like Wilson Audio, Sonus faber, and Magnepan, making it a versatile choice for serious audiophiles.

Built for the Music Lover in Mind

Crafted by hand in Audio Research’s Maple Grove, Minnesota facility, the Reference 160 S Power Amplifier is designed to bring music to life in every sense. From the smallest whisper to the loudest crescendo, the 160 S excels at capturing the full dynamic range of your favorite recordings. The amplifier’s four KT150 output tubes and four 6H30 tubes in the gain stage contribute to its extraordinary performance, offering both power and finesse.

The amplifier is not only a sonic powerhouse but also a visual masterpiece. It shares the same dimensions as the Reference 160M, featuring a sturdy chassis that includes rear handles to make positioning easier. In addition, it has 120mm low-profile fans integrated into the bottom cover plate to provide silent and efficient cooling, ensuring reliable performance even during extended listening sessions.
