conrad-johnson It just sounds right.
The ET2 is a remote-controlled vacuum-tube
preamplifier designed to serve as the control
center for high-performance audio and audio/
video systems. The ET2 features a sophisti-
cated level control circuit designed to allow
precisely repeatable level and balance settings
with adjustments made in .5db increments.
With seven inputs, the ET2 will accommo-
date even quite elaborate audio systems. The
ET2 includes a Theater Loop which provides
a locked unity gain setting, making it the
ideal component for listeners who wish to
integrate home theater into their stereos with-
out compromising the performance of their
primary music system.
The ET2 zero-feedback line-stage circuit con-
sists of a single-ended triode amplifier using a
high current vacuum tube. A direct coupled
buffer stage provides a low output impedance
to insure that the ET2 can comfortably drive
virtually any combination of interconnect
cable and power amplifier. This circuit’s sim-
plicity pays dividends in tonal integrity and
seductive musicality while offering flexibility
in system matching.

The ET2 is optionally available with a choice of two built-in phono equalization preamplifier stages (a high gain stage and a low gain stage) to provide the additional gain and RIAA equalization that phono cartridges require. The phono circuit uses two tri-ode amplifier stages for voltage gain. A passive net-work of precision components accurately provides the required frequency compensation. A direct coupled buffer stage isolates the phono stage from external
cables and components connected to the EPL and Theater outputs. The circuit employs no negative feedback loop, eliminating feedback induced timing errors that compromise dynamics and imaging. The high gain phono stage is suited for use with low to medium output moving coil cartridges with rated output of 1.0 mV or less. The low gain stage is recom-mended for cartridges with output above 1.0 mV.
