ET3 Valve Line Preamplifier w/Remote

At conrad-johnson, development of their 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 their 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.


It would be fair to say that the only thing “entry-level” about the ET3 is its price.  You’ll be surprised at just how affordable true high-end performance can be.
