The Expert Pro series features many renowned Devialet technologies. 

ADH: Analog-Digital Hybrid

This technology delivers the musicality of analog and the power of digital. Devialet are the acknowledged masters of refining class D amplifier topologies and creating truly dynamic, musical, and breathtaking experiences. ADH, or analog-digital hybrid, uses class-A circuitry with class-D output stages resulting in an incredible damping factor for exceptional speaker control.

SAM: Speaker Active Matching

A game-changing innovation, SAM® enables Expert Pro to produce a signal ideally suited to your exact speaker model, thanks to advanced mathematical modeling of its acoustic architecture determined by SAM Lab. With perfect temporal alignment and greater extension into low-end frequencies, the sound stage is exquisite. Revolutionary, SAM® technology ensures you get the best from your speakers while providing permanent protection from overload. 800+ speaker models are now SAM-ready, and yours are certainly among them.

RAM: Record Active Matching

The most advanced phono stage ever created. With next-generation RAM® technology, your Expert Pro phono stage becomes instantly and endlessly configurable, working in real-time to custom fit the exact characteristics of your turntable or vinyl records.

RAM offers over 250 different combinations to perfectly suit your cartridge, and also allows you to adjust EQ dynamically and with unrivalled accuracy.

Magic Wire® DAC

By inventing Magic Wire® technology, Devialet was able to achieve the shortest signal path ever reached between DAC and connected speakers: just 5 cm. A world record. Magic Wire® works by avoiding potential audio signal imperfections, providing seamless impedance matching and keeping unwanted noise to an absolute minimum.
