Audio Research has made history with industry-landmark preamplifier designs such as the SP3 in 1973, and again in 2010 with the Reference Anniversary preamplifier. In particular, The Reference Anniversary was a special limited-edition product commemorating our 40th year.
 
At the time, it was acclaimed by many as the finest preamplifier available and a fitting tribute to all the classic Audio Research products that were introduced since the company’s birth. We were met with disbelief that we would only accept orders for this special product during the anniversary year, yet we considered the limited time frame appropriate. But in the years that followed, research and advancement inexorably reached further. The result is the best preamplifier Audio Research has yet devised, the Reference 10 line stage.
