Available in six colors, the I/50 features Cerakote finishes for a beautiful and long-lasting look. The modular design allows for the installation of two audio modules – a Phono Stage (£798), and a D/A Converter (to come in 2023).

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.

The performance of the I/50 belies its compact design. 50 watts of all-vacuum tube power energize your speakers with beautiful and lifelike music. Designed by the Audio Research engineering team and fine-tuned by our sonic designer, the I/50 has been given the same level of care and attention as our Reference Series products. .
