Power Amplifiers

At the heart of our Power Amplifiers is decades of proven Audio Research vacuum tube technology, a legacy unrivaled by any other manufacturer of tube electronics. Developed through hundreds of hours of critical listening, the carefully selected components comprising our Power Amplifiers combine to provide an array of amplifiers which transcends traditional hi-fi, instead relaying music with realism and tangibility.


Audio Research has produced some of the finest components for music reproduction; this is especially true with regard to preamplifiers. In 1973, the SP3 was hailed as the best preamplifier available, and this tradition of excellence has continued ever since. The Reference Series from Audio Research was first introduced in 1995 and has been the ultimate representation of performance, musicality and power.
