Audio Research Reference 10 Preamp Mint as New [Expired]


no longer for sale

Here we have a Mint condition never being used before REF10 PREAMP from Audio Research in Silver. I would say it is a New item but since it is opened box I would put a 10/10 Mint condition.

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. Our logo is above the knob on the right, making this the first asymmetrical Audio Research pre-amplifier ever. 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 we 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.
