In 2010 Audio Research announced the Reference Anniversary preamplifier, a special limited edition product commemorating their 40th anniversary. It was acclaimed by many as the finest preamplifier available and a fitting tribute to all of the classic Audio Research products that were introduced during the forty years that preceded it. Since that time, Audio Research have learned a few things, and the result of that knowledge led to the development of the Reference 10. Included are critically chosen new components, proprietary custom-made capacitors, wiring, and new connectors that cumulatively provide a level of performance never before achieved. Key Audio Research design traits remain: The signal path is fully discrete, all-tube, pure Class-A, with zero feedback. Other attributes and choices remain, too: Each unit is completely hand-soldered and hand-constructed in their Minnesota facility using the finest materials, with major components such as custom transformers, plated-through circuit boards, and casework sourced locally. All engineering is performed in-house.

The Reference 10 follows a new aesthetic path as well. It has a very modern and elegant finish that will attract new admirers without alienating fans of our older products. The front panel of the main control unit has a new, large round volume knob on the right side, with two buttons under it for Power and Mute - the only two buttons on the unit - and a large display on the left. The left side of the front panel contains an interactive touch-screen display that allows the user to intuitively control almost all functions.

The power supply chassis, connected to the main unit via two umbilical cords, simply has one green LED under its offset Audio Research logo. All of the side panels are finished identically to the front panels: Natural anodized, one quarter-inch thick, with no screws visible. The entire chassis (including rear panel) is painted silver to complete the look. There are beautiful new, clear acrylic covers with a revised perforation pattern. And, there is no printing on the front panel of either chassis.

After the single 20A power cord, the Reference 10 is completely dual-mono from the power supply through the audio circuit. There are dual, separate low- and high-voltage transformers for each channel; there is dual-mono vacuum-tube regulation (one 6H30 and one 6550WE per channel), dual-mono audio circuits (four 6H30 per channel), and enough energy storage for a serious power amplifier.

Just as the Reference Anniversary was shockingly better than its predecessors, the Reference 10 offers a further level of resolution, refinement and dynamism that vividly improve the musical experience in every way. As Audio Research have said before, words can only fall short of your own experience; to understand how much more profound listening to your favorite recordings can be, you must hear the Reference 10. It is stunning.
