Product Highlights

Optional DAC and Phono stage not installed.


"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 Warren Gehl, the I/50 has been given the same level of care and attention as our Reference Series products. The ability of the I/50 to reconstruct a musical experience will thrill and excite all who hear it. Thanks to the substantial power supply and high current design, the I/50 provides controlled and dynamic playback – even on challenging speakers." - Audio Research

There are also some light nicks around the top and sides of the chassis and transformer case.
