Audio Research Reference 10 Preamp Mint as New

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.
