Devialet Expert 440 Pro Dual

All the Promises of an Expert Pro System


The Expert 440 Pro combines two Expert 220 Pro units and offers up to 16 physical inputs and 440W of power per channel, for a Dual-Mono set-up without any compromise.



Incomparable Performances.

Expert Pro is the world’s most advanced audiophile system, meant for music lovers in search of a refined and emotional listening experience. Designed to replace traditional Hi-Fi systems, Expert Pro delivers all the core elements of playback – preamp, amp, DAC, streamer, phono stage – in a single and ultra-compact unit.


Entirely Configurable.

By rethinking sound reproduction at every turn, Devialet engineers have been able to achieve the best performance ever measured, at all power levels. Entirely configurable and upgradable, Expert Pro reveals your music’s full potential, whatever the source or speakers. Utter connectivity for the most demanding audiophiles. The Expert 220 Pro embeds the full set of Devialet technologies, as well as an ultra-configurable phono stage, designed for vinyl enthusiasts. The Configurator is Devialet's online user setup tool, allowing for phono stage loading in the phono preamp, crossover filters for specific speakers, and other vital audio settings. 3 different user settings can be saved to the included SD card that uploads the settings into the Expert Pro Amplifier.  


A Score of Leading-edge Technologies.

ADH® hybrid amplification delivering the musicality of analog and the power of digital, SAM® real-time speaker active matching, on-the-fly phono stage configuration with RAM®, Magic Wire® DAC to eliminate thermal distortion, free and regular upgrades through the EVO® platform…Exclusively developed by Devialet engineers, these technologies radically enhance every aspect of Expert Pro’s architecture. And with Core Infinity, Expert Pro’s new intelligent core, streaming your music without compromising sound quality is both simple and accessible.

From a mathematical model of your speakers, SAM® Speaker Active Matching enables your Expert Pro to adapt accurately the signal transmitted to them. For the first time, it is then possible to obtain a perfect time alignment between the recorded signal and the sound pressure generated by the speaker drivers to achieve the emotional power of music; just as the artist intended.

SAM® is an electro-acoustic revolution. For the first time ever, Devialet SAM technology guarantees a seamless match between your amplifier and connected speakers. Almost all multi-way loudspeakers generate delay caused by the bass diaphragm reacting slower to the audio signal than the tweeter does. Mechanical and technical measures help to minimize delay that would otherwise disrupt the evenness and spatial quality of sound. Preliminary laboratory work carried out via SAM® Lab enables us to identify sixty or more different parameters per speaker model.

SAM® analyzes transducer characteristics using laser technology. These include displacement, deformation, maximum displacement, speed and acceleration. By measuring passive filters, we can determine resonance (event bass-reflex and passive radiators) while factoring in the overall impact of casing and damping. Once this data is compiled, SAM® is able to produce a full physical behavioral model. The collected data also allows us to calculate the transducer SOA (Safe Operating Area). By doing so, SAM® offers permanent protection from overload, letting users reach higher volumes than ever before.

Similar to transfer function, this physical model is inverted in real time using digital signal processing technology before digital-analog conversion occurs. The result: acoustic pressure in the air perfectly matches the signal registered by microphones during the recording process.


The World's Most Advanced Phono Stage

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.
