GAT Triode Preamplifier

The GAT Preamplifier embodies conrad-johnson’s latest advances in line-stage preamplifier technology. We believe that it will quickly be recognized as the new industry-wide reference standard for line-stage preamplifier performance, a role filled for more than a decade by its legendary predecessor, the ART preamplifier. Like the ART, the GAT Preamplifier will be available in a numbered, limited edition of 250 units which will be sold through selected conrad-johnson dealers.

The GAT Preamplifier is a vacuum-tube, line-stage preamplifier that looks as good as it sounds. It is also notable for convenience and ease of use. The unit features input selection and level adjustment by microprocessor-controlled relays. Level and balance can be adjusted in 100 steps of approximately .7 dB per step. All functions can be controlled by the hand-held wireless remote control.

ET5 Enhanced Triode Preamplifier

Introduced in 2009, the GAT Preamplifier continues conrad-johnson's dominant position atop the rankings of reference preamplifiers. An important benefit of pursuing state-of-the-art designs is that the circuits and techniques developed in our flagship products are frequently directly applicable to our entire line of products. In this instance, we have embodied the technology of the GAT Preamplifier in the more cost effective ET5 enhance triode line-stage preamplifier at a more affordable price.

ET3 Vacuum-Tube Preamplifier

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.

The Classic-2 Vacuum-Tube Preamplifier

For more than thirty years, conrad-johnson has refined the concept of high end audio through its relentless pursuit of excellence. For as long as the company has been producing its world-renowned state of the art audio instruments, it has also been adapting the technologies and construction techniques responsible for those products and applying them to more affordable components designed for the music-lover who requires musically satisfying performance but whose budget does not encompass the loftiest of current offerings. The conrad-johnson Classic-2 vacuum-tube preamplifier honors this thirty-year heritage of musically accurate, moderately priced preamplifiers which have displayed the conrad-johnson name.

The Classic-2 faithfully reproduces the harmonic structure of complex musical passages, preserving the distinctive tonal character of each instrument and voice. The space of the sound stage and the ambience of the concert hall are conveyed in realistic, three dimensional perspective. Individual instruments are precisely located within that three dimensional space. Musical transients are reproduced naturally, with realistic impact, but without the artificial enhancement which characterizes so many "hi-fi" components. Never imposing its own distractions, the Classic-2 invites the listener to enjoy the musical performance.
