Audio Research is one of the oldest continually operating manufacturers in American audio. The company was founded in 1970 in Minneapolis with one goal in mind: to advance the state-of-the-art in music reproduction. Today, Audio Research remains a performance-oriented company by philosophy and design, they don’t use valve technology as a craze or a fad, and they are future classic audio products in their own right. New product introductions are driven only by genuine advances in technology and performance -- the HIGH DEFINITION that is the hallmark of the company's products. Much more than a mere carriage-trade brand name, the Audio Research marquee has come to represent stellar performance and lasting value for music lovers and audio enthusiasts everywhere.
