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.
