Devialet was founded in Paris in 2007 by three engineers — Quentin Sannie, Pierre-Emmanuel Calmel, and Emmanuel Nardin — who asked a question that most of the audio industry considered settled: was it truly impossible to build an amplifier that combined the power and dynamic range of Class A/B solid-state with the harmonic purity of pure Class A, in a form factor small enough to live in a modern home? Their answer, after years of development, was a patented circuit topology they called Analog Digital Hybrid (ADH) — and the result was an amplifier unlike anything that had existed before. Devialet's Paris headquarters now employs more than 200 engineers, all working on the same fundamental problem: how to make extraordinary sound reproduction physically accessible. ENGINEERING PHILOSOPHY Devialet's ADH technology combines a digital switching amplifier — which provides power efficiency and thermal management — with an analogue Class A amplifier that handles the output signal. The digital stage provides power; the analogue stage provides purity. The result measures at distortion levels below 0.001% and signal-to-noise ratios that exceed anything achievable through conventional analogue design. The Phantom series takes this further, integrating the amplification, digital processing, and acoustic driver system into a single sealed enclosure, eliminating the cables, connectors, and impedance mismatches that compromise conventional component systems. The SAM (Speaker Active Matching) system applies a unique equalisation profile derived from physical modelling of the acoustic drivers, allowing the system to operate closer to the physical limits of the drivers than any passive crossover could achieve.

Unique, compact and extreme design. Devialet Astra epitomises the fusion of form and functionality. While staying true to the slim silhouette, signature of the Expert series, Devialet Astra's design has been thoroughly modernised to enhance both aesthetics and usability. Sound. Like you never felt it. With these proprietary technologies, Devialet Astra not only adapts to your current audio setup but evolves with your changing preferences. Analog Digital Hybrid Devialet Astra embarks the latest generation of our proprietary ADH® technology, unlocking the widest frequency range possible. Central to Devialet's legacy, this technology works by simultaneously harnessing all the linearity and refinement of analog amplification (Class A) and all the power and compactness of digital amplification (Class D), delivering Hi-Res sound that stands out both in impact and precision. Precision in Hand. Devialet Astra also comes equipped with a redesigned remote. Matching Devialet Astra's sleek casing, it features a built-in screen for real-time feedback on actions like volume setting and playlist navigation. And its central knob allows for ultra-precise volume control in 1 dB increments. The remote is battery-powered and can be easily charged via USB-C. Speaker Active Matching SAM® next-gen technology precisely matches the audio output to the specifications of passive speakers, preserving their acoustic signature in real time. This advanced technology ensures even finer adaptation of the sound signal and perfect time alignment between the recorded signal and the sound pressure generated by the speaker's drivers: the secret to more impactful bass. Record Active Matching RAM® technology allows dynamic equaliser adjustments tailored to the characteristics of your turntable or vinyl records, seamlessly adapting the phono stage for optimal performance. A bijou of French engineering. Devialet Astra's amplifier redefines expectations with its radical form factor. Strikingly sleek, thin, and compact, it stands in a world of its own, delivering bleeding-edge technology in a form that enhances any space.
