Description
The Audio Research Reference 3 is a preamplifier known for its musical transparency and impressive soundstage. It offers a wide frequency range and low distortion level, resulting in clear and detailed music reproduction.
The Audio Research Reference 3 was developed according to the “High Definition” design philosophy of William Z. Johnson, founder of the brand. The preamplifier uses selectively chosen audio tubes (6H30) and high-quality components such as audio-grade capacitors. The internal wiring is hand laid and the housing is aluminum, for optimum vibration damping. Everything is assembled by hand in Minnesota, USA.
Audio Research was founded in 1970 in Minneapolis, Minnesota, United States, by William Zane Johnson. The company began developing electronic tube equipment, starting with the SP-1 preamplifier. Over the years, the brand introduced several products, including the D-150 power amplifier in 1974 and the original REF1 in 1995. Audio Research moved its headquarters to Maple Grove, Minnesota, in 2007. In 2020, the company was acquired by AR Tube Audio Corporation, led by former employees. Audio Research manufactures all of its products in the United States and focuses on manual assembly of equipment. Repairs and maintenance can be done in-house. The company uses hand-wired point-to-point wiring combined with printed circuit boards. Documentation and schematics of products since 1970 are available through the company, and parts are kept in its own warehouse.
