Brand: Audio research
The Audio Research D-111 is a high-end integrated amplifier that was introduced in the early 1990s. It features a power output of 60 watts per channel into 8 ohms and a range of inputs and outputs, including four RCA and one XLR input, and a tape monitor and a preamp output. The D-111 has a dual-mono construction, meaning that each channel has its own power supply and signal path, which helps to reduce interference and improve overall performance. It also uses Audio Research's famous "black boxes" technology, which are heavily regulated and filtered power supply modules that help to eliminate noise and distortion. The Audio Research D-111 is highly regarded by audiophiles for its natural, detailed sound and is considered a classic in the high-end audio industry.
