Our design philosophy is the culmination of more than 40 years of research and development. conrad-johnson products are executed with simple circuits, constructed with the highest-quality custom components. Our products benefit from the use of proprietary components (CJD film capacitors, audio and power transformers), military-grade parts (precision audio resistors), and in-house designed elements (circuit boards, chassis and dress metal)—all sourced from North American vendors.
All c-j components are designed and built by hand in the USA.
Our products are a manifestation of our passion. Performance cannot merely be measured; it must be heard. It just sounds right.
This latest rendition of our enhanced triode circuitry incorporates the power supply circuit upgrade from the GAT Series 2 (and subsequently found in the ET7). The ET6 also features upgraded I/O connectors and beautiful new casework.
The ET7-S2 enhanced triode line-stage preamplifier has been designed to incorporate the advances made with the Series 2 upgrade to our flagship GAT into a more affordable model.
The conrad-johnson design team is committed to adapting the advances from our state-of-the-art pursuits to more affordable offerings accessible to a wider range of music lovers.
For more than 4 decades, our vacuum tube preamplifiers have set the industry standard for performance, garnering worldwide acclaim and a place in many a reference system.
Since our first amplifier, the MV75 of 1978, c-j vacuum tube and solid state amplifiers have defined the state of the art. Our line features power amplifiers to fit nearly any requirement.
