About Audio Research
When Audio Research was founded in 1970 by Bill Johnson, he had one goal in mind: to advance the state-of-the-art in music reproduction. Today, Audio Research remains true to its roots as a performance-oriented company driven by proven philosophies and superior design. Many industry observers consider Audio Research one of the true originators of the concept of “high-end” audio, offering an unsurpassed level of performance that can easily be heard and appreciated by all. Over its first half-century, Audio Research has grown from a small operation in the back of Bill’s shop to a modern, self-contained factory with dedicated R&D, testing, manufacturing, quality control, and listening facilities. Manufacturing is done by hand in-house, from the ground up, in our Minnesota facility. (Contact us for a tour if you are near Minneapolis, it’s fascinating to meet the people and see the process in action.) 330M Monoblocks Launched May 2024

GhostMeters™
REF160S carries-over the stunning look of the 160M, with dual GhostMeters™ that float in front of the eight KT150 output power tubes. Also continued is the the feature set introduced in the 160M, including a proprietary auto-bias circuit, switchable Triode or Ultralinear modes of operation, balanced and single-ended inputs, and an output tube monitoring mode. The 160S also uses a four-layer circuit board, allowing music to emanate from a jet-black background. With a weight of 100 lbs. the REF160S distills the astonishing resolution, dynamic impact, musical purity and finesse of the 160M into one beautiful and attainable chassis. It was designed for the music lover in all of us.
