The Audio Research I/50 Integrated Amplifier, launched in September 2021, is a high-fidelity, all-vacuum tube amplifier from the legendary American manufacturer. It delivers 50 watts per channel (6550WE power tubes) for compelling audio reproduction. This modular unit includes Audio Research’s optional Phono Module, providing 42 dB of gain for both Moving Magnet (MM) and high-output Moving Coil (MC) cartridges, enabling direct turntable connection. It also features three RCA inputs, one XLR input, and a 1/4″ headphone jack.

Distinguished by its vibrant Cerakote finishes (six colors) and unique LexieTubes® display, the I/50 combines striking aesthetics with user-friendly operation. Hand-crafted in Minnesota, its robust build and powerful, transparent sound make it an ideal centerpiece for discerning audiophiles seeking a complete, high-performance analog system.

- The I/50 Integrated Amplifier is the first product in an all-new series from Audio Research. Functionally simple, visually engaging, and musically sublime – the I/50 takes music listening to a whole new experience.

- Hand-crafted in Minnesota, the I/50 is built with the same attention to detail as all other Audio Research products – each one even gets its own listening test with sonic designer, Warren Gehl.

- The high current, 50 watt per channel amplifier is capable of driving a wide variety of speakers. A headphone jack allows for personal listening time.

- The I/50 is designed to be easy to use, and has three controls on its top panel – Power, Input, and Volume. Two LexieTubes® provide display information for input selection and volume.

- A full-function metal remote control provides further functionality and operation. An optional tube cage will be available.
