At conrad-johnson, development of our flagship products has traditionally led
to important enhancements of our entry-level offerings. The ET3 preamplifier is
a case in point. The ET3 line-stage is a “baby” version of our flagship
line-stage preamplifier, the GAT. The family resemblance is much more than skin
deep. With voltage gain provided by a triode vacuum-tube, the zero-feedback
line-stage circuit of the ET3, along with its DC voltage regulators, closely
replicates the circuit of the GAT. Finally, and especially noteworthy, the ET3
features a relay operated discrete stepped attenuator level-control circuit of
the type found in the GAT and CT5, absent only the balance control function
found in those more costly models.
Functionally, the ET3 provides highly flexible I/O facilities with six
separate line-level inputs (including one “tape” loop), plus a theater loop that
facilitates use in a home theater system. In addition, the ET3 offers the
convenience of infrared remote control of all functions.
For vinyl enthusiasts, the ET3 is optionally available with a vacuum-tube
phono stage that borrows its zero-feedback audio circuit from our reference
quality TEA1 phono stage. Customers can choose between high gain (recommended
for cartridges with a rated output of 1.0 mV or less) and low gain (recommended
for cartridges with rated output greater than 1.0 mV) versions of the phono
stage. Input resistive loading is switch selectable over a range from 47 kOhms
down to 200 Ohms. The ET3 phono stage is built to the same high quality standard
found in the ET3 line-stage
It would be fair to say that the only thing “entry-level” about the ET3 is
its price. Arrange to audition one at a conrad-johnson dealer to find out for
yourself – you’ll be surprised at just how affordable true high-end performance
can
be.
