Reference Phono 2 Vacuum Tube Phono Preamplifier
After our original Reference Phono preamplifier was discontinued in 2005, the demand for a Reference-level
successor never declined. Not satisfied with introducing a replacement that would be incrementally better, we were
determined to develop an all-new vacuum-tube phono preamplifier that would truly advance the state of the art.
Years of development have come to fruition and we are proud to introduce the fully balanced Reference Phono 2.

Physically, the Reference Phono 2 is similar to our other Reference preamplifiers, with slab side panels, a vacuum-
fluorescent display, and the same height and depth as its predecessors. The front panel has six control buttons for
Power, Input, Gain, Load, RIAA and Mute. New silver handles are standard on natural-anodized units, while black
handles come with black-anodized units. For owners wanting to match other Audio Research components, black
handles are available, just as new silver handles will be available for most other Audio Research components.

The feature set of the Reference Phono 2 is extensive. There are two separate sets of inputs, with gain selectable
between Low (51dB BAL / 45dB SE) and High (74dB BAL / 68dB SE). There is a choice of seven loading selections
including 47K, 1000, 500, 200, 100, 50 ohms, and Custom, which we can factory-set according to your need. (If not
specified, the Custom load is 47K.) In addition to standard RIAA phono equalization, the Reference Phono 2 also
includes early stereo Columbia and Decca equalization curves. The display will show all selected functions (Input,
Gain, Loading, EQ, Mute, Tube Hours), and its intensity can be adjusted to one of six levels, plus off. When the
display is off, nine small pixels will remain lit in the center as a discreet reminder that the unit is powered on – touch
any button, and the display comes on for ten seconds. The microprocessor will remember the independent settings for
each input, and the supplied remote will control all of these functions.

The Reference Phono 2 is a fully balanced design with an input circuit that allows its RCA inputs to operate in a
balanced configuration without requiring an inverter. It shares the same tube complement as the Reference 3 and
Reference 5 line-stages, and also the Reference CD8 compact disc player; four 6H30s in the gain stage with a 6550C
and 6H30 in the power supply. The Reference Phono 2 also features the same basic analog stage as its acclaimed
siblings. Rather than using a step-up transformer, special high-gain, extremely low-noise FETs are used in the high-
gain section. This approach is costlier than using a transformer, but it is well worth it for the dramatic increase in
performance. There are new, proprietary capacitors throughout, the transformers are new, and there are eleven stages
of power supply regulation.

Connections on the rear panel include two sets of RCA inputs with ground post, XLR and RCA outputs, and a 20A
