Audio Research I/50 Integrated Amplifier

With 50 watts per channel, the I/50 performs best with speakers of moderate to high sensitivity. Because it features selectable impedance taps for 4, 8, and 16 ohms, it is highly versatile and can drive a wide range of bookshelf and floorstanding speakers effectively.

Yes, the I/50 features a built-in, audiophile-grade phono stage designed to handle moving magnet cartridges. This allows you to connect your turntable directly to the amplifier without needing an external preamp.

As a tube-based amplifier, the I/50 requires periodic replacement of the vacuum tubes to maintain optimal sound quality. While this is standard for high-end tube gear, the unit is designed for straightforward access to ensure the process is manageable for the user.

Yes, the I/50 includes a high-fidelity headphone output on the front panel. It is engineered to provide the same level of transparency and detail as the main speaker outputs, making it an excellent choice for private listening sessions.

The I/50 is equipped with an integrated digital-to-analog converter that supports high-resolution audio playback. It is designed to bridge the gap between modern digital sources and the classic warmth of a tube-based analog signal path.

The integrated design combines the preamplifier and power amplifier into one chassis, reducing the need for extra cables and minimizing potential signal interference. It offers the signature Audio Research sound in a more compact, simplified footprint that is easier to integrate into a living space.
