Conrad Johnson CT5

Description

Description Freakuence!

Thick thing. The tubes nicely planned in a horizontal vault. Very immersive reproduction without the sharpness of some solid-state amplifiers.

General description

The Conrad-Johnson CT5 is a line preamplifier known for its musical honesty and listening pleasure. Its design is focused on delivering rich and solid sound reproduction, with attention to the energy and presence of musical instruments and voices.

The device uses a composite-triode circuit, a technique that switches multiple devices in parallel to achieve optimal performance. This contributes to the CT5’s balanced and musical coherence, enabling it to accurately reproduce the color and texture of a performance.

The CT5 is equipped with a relay-controlled discrete volume control, similar to that found in Conrad-Johnson’s GAT and ACT2 models. This provides accurate and consistent volume control, contributing to overall sound quality.

With its solid and purposeful design, the CT5 exudes confidence. It is a device that focuses on long-term satisfaction and listening pleasure, without being swayed by trends or fads.

Background information

The Conrad-Johnson CT5 was designed by Bill Conrad and Lew Johnson, with a philosophy focused on musical accuracy over technical perfection. The preamp uses high-quality, carefully selected components such as Teflon capacitors and discrete resistors. The internal wiring is done by hand for optimal signal transmission. The cabinet is simple but robust, designed to combat microphonics and minimize electrical interference. Everything is assembled by hand in the USA.

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.
