CONRAD-JOHNSON - ET3 line preamplifier (15.06.2010)

Conrad-Johnson has announced a new entry level preamplifier, the ET3. The ET3 is described as a "baby" version of the GAT (flagship line-stage preamplifier from CJ). The line-stage circuit of the ET3 is virtually the same as that of the GAT. DC regulators patterned after those used in the GAT provide stable DC voltage to the audio circuits. Finally, and especially noteworthy, the ET3 features a relay operated discrete level-control circuit of the type found in the GAT and CT5 line stages.

The ET3 provides six separate line-level inputs (including one tape loop), plus a theater loop that facilitates use in a home theater system. Infrared remote control of all functions is also provided.

Premium quality component parts are specified for the ET3 to optimize performance and reliability of the circuit designs. Precision, metal-film resistors yield low noise performance. Polypropylene capacitors, used exclusively in the audio circuits and the regulated plate voltage supplies, ensure temporal accuracy.

For vinyl enthusiasts, the ET3 is optionally available with a phono stage card that borrows its circuitry from Conrad-Johnson TEA1 phono stage, with the same standard of parts quality as the line stage. For customers seeking higher level of refinement, a Special Edition will be available which will include upgraded I/O connectors, teflon bypass capacitors, and extensive use of Vishay resistors.
