Description Freakuence!
Delicious and honest. A smooth preamplifier with an “ear for detail. The unit is beautifully built. Plays naturally and musically, with exceptional detail and dynamics. The built-in phono stage provides some extra fun for the record fanatic!
General description
The Conrad-Johnson ET6 SE is a tube preamplifier that closely follows the design of the GAT, Conrad-Johnson’s flagship product. With a triode vacuum tube for voltage amplification and zero-feedback line-stage circuitry, the ET6 SE offers sound quality far beyond what you would expect in this price range.
The preamplifier features six separate line-level inputs, including a “tape” loop and a theater loop, facilitating integration into a home theater system. In addition, there is an infrared remote control for all functions.
For vinyl enthusiasts, an optional phono stage is available, based on the zero-feedback audio circuit of the TEA1-S3 phono stage. You can choose between a high-gain version for cartridges with an output of 1.0 mV or less, and a low-gain version for cartridges with a higher output. The input resistance is switchable between 47 kOhm and 200 Ohm.
The ET6 SE uses high-quality components such as CJD Teflon capacitors and metal foil resistors at critical points in the circuit. This contributes to low noise and clear sound reproduction.
With its flexible connection options and attention to detail in design, the ET6 SE is a preamplifier that will appeal to music lovers and audiophiles alike.
Brand history
Founded in the mid-1970s in the US by two friends with anything but musical backgrounds. In fact, Dr. William Conrad and Dr. Lewis Johnson were economists by trade…. but with a very strong audiophile passion. Conrad-Johnson products are implemented with simple circuitry, but built with the highest quality custom components.
Questions & Answers
How is the volume adjusted on the ET6 SE?
Volume is controlled via a discrete, relay-controlled step-attenuator, similar to those in the GAT and ET7 models, but without balance control.
What connection options does the ET6 SE offer?The ET6 SE features six line-level inputs, including a “tape” loop and a theater loop for integration into a home theater system.
Is the ET6 SE compatible with both MM and MC cartridges?Yes, the optional phono stage is available in a high-gain version for MC cartridges and a low-gain version for MM cartridges.
How many tubes are used in the ET6 SE?The ET6 SE uses a single 6922 triode vacuum tube in the line stage.
What is the output impedance of the ET6 SE?The output impedance is 100 ohms, ensuring compatibility with a wide range of amplifiers.
Can the ET6 SE be operated with a remote control?Yes, all functions of the ET6 SE can be controlled with an infrared remote control.
What are the dimensions of the ET6 SE?The dimensions are 16 inches deep, 19 inches wide and 3.75 inches high.
What is the frequency range of the ET6 SE?The frequency range at unity gain runs from 2 Hz to over 100 kHz.
Is the ET6 SE equipped with a theater bypass function?Yes, the ET6 SE has a theater loop that allows integration into a home theater system.
