Think outside the box and achieve performance. This is Solen’s philosophy.
Rather than simply optimising traditional designs, Solen strives to imagine new approaches, explore alternative architectures, and challenge established norms. Equal importance is given to the aesthetics of its products. This spirit of research and creativity guides every stage of the design process.
Solen amplifiers are entirely made in France. The metal enclosures are precision-machined locally, and both power and output transformers—specifically designed for Solen’s Circlotron technology—are wound to Solen’s exact specifications. Final assembly takes place in Grenoble.
The CV40-E84 Tube Amplifier is Solen’s fully tube Circlotron amplifier, combining the natural musicality of valves with the speed and control of transistor designs. Powered by a quad of EL84 tubes delivering 40 watts, it offers exceptional dynamics, precise imaging, and effortless loudspeaker control.
Designed and built entirely in France, the CV40 features custom-wound transformers, a dual-mono power supply, automatic tube biasing, and an all-aluminium chassis—bringing together innovation, craftsmanship, and timeless aesthetics.
