REFERENCE PHONO 3

VACUUM TUBE PHONO PREAMPLIFIER

When Audio Research was founded in 1970, analog vinyl playback was the de facto
music source of the time. Audio Research has either incorporated or
built stand-alone phono stages since the very beginning, and has
continuously provided phono preamplification, even during the height of
digital music. The Reference Phono 3 is the next advancement of analog
playback.

The Reference Phono 3 is a continuation of the work which has been
evolving other components in the Audio Research Reference Series over
the past year. In mid-2015, all of the amplifiers received significant
performance enhancements with the SE updates - new output tubes,
components, and other parts ushered in a new level of sonic accuracy and
musicality. This exposed a need for higher resolution and dynamic
capabilities in components upstream from the amplifiers, and in October
2015 the Reference 6 was introduced. The Reference Phono 3 is the next
step in our pursuit of musical realism.
Like the Reference 6, the
tube count in the analog section Reference Phono 3 has been increased
from four to six. The power supply has been redesigned to accomodate the
additional tubes, as well as provide a greater dynamic range. Numerous
other components and parts, including proprietary coupling capacitors,
wiring and cryogenically-treated pieces advance the playback experience
to a level reminiscent of master tape playback for a realism and
palpability previously unavailable.

The Reference Phono 3 phono
preamplifier is housed in a single chassis paneled in custom-machined
aluminum. The vacuum tube audio stage utilizes six 6H30 vacuum tubes
(three per channel), and one 6H30 and a 6550WE provide regulation in the
power supply. The large, vacuum fluorescent display on the front panel
shows all functions relative to the selected input. A row of six buttons
control power, mute, input, and menu controls. Menu functions include:
auto shutdown, gain and load settings, display brightness, equalization
settings, and tube hour reset. High and low gain settings, as well as
six fixed and one custom impedance setting, accomodate most any moving
magnet or moving coil cartridge. Two single-ended inputs provide
connectivity to two turntables. There are two main outputs providing
both balanced and single-ended outputs. RS-232 and IR input allow for
additional control options. The Reference Phono 3 ships with a
full-function metal remote.
