Devialet Expert Pro is the ultimate audiophile system, for the most discerning of music lovers.

Well above and beyond an ordinary amplifier, Devialet reinvents and combines for the first time all of the key components of expert playback (pre-amplifier, amplifier, DAC, streamer, phono stage) in a single and extremely thin slab.

Your Devialet Expert Pro is unlike any other: set each of the thousands of possible configurations for a unique musical experience.

Regardless of the source. Regardless of the speakers.

Unmatched performance

Dual-Mono: 2 x 440 Watts @ 6Ω

Exceptional architecture and performance.

The Dual-Mono Expert Pro configuration is able to achieve new heights in performance, in particular with a distortion divided by 2 compared to the stereo system, more power for each channel and an extreme variety of connectors for the most demanding acoustic architectures.

The Expert 440 Pro includes all Devialet exclusive technologies as well as major innovations developed for the new Expert Pro range.

0.0005%THD+ noise (harmonic distortion) at full power
0,00025%THD at 10W/6Ω
0.001Ω Output impedance
133 dB Signal-to-noise ratio
Devialet inventions

ADH® analogue-digital hybrid amplification, SAM® system for real-time adaptation of the signal transmitted to the speakers, free, regular updates using the EVO® platform, HD audio stream (wired or wireless) via AIR®, DAC Magic Wire®, RAM® Phono stage… The Expert Pro system is an engineering gem.

All Expert Pro systems incorporate all of Devialet’s audiophile technologies. 107 patents. 62 awards. The most award-winning audio system of all time.

In addition to these technologies exclusive to Devialet, Expert Pro benefits from many major innovations developed for this new line to push once again the extreme limits of audiophile performance:

New ADH Intelligence®

Each element of the ADH core has been carefully rethought in order to design the most advanced version of the ADH Intelligence® which provides significant performance improvements at all power levels. The THD is then reduced at lower sound levels. The sense of the Class A amplifier has been improved from 8 bits to 10 bits (or 1024 levels instead of 256), multiplying the precision of the ADH core’s control by 4.In addition, thanks to a new and more performant control algorithm, the regulation of the ADH loop is even more responsive.

New Magic Wire® DAC

The pure performance in digital – analogue conversion sets a new world record with a THD improved by more than 6dB and a noise floor lowered by 2.5dB. Less transistors have also been used to guarantee the most accurate reproduction of your music.

New Class A Amplifier

The design of the Class A amplifier has been simplified: the signal crosses two silicon junctions less to reduce the THD even more. In addition, zero current goes through the Class A in standby mode for a minimal power consumption of the system.

New Class D Amplifier

Enhanced with the new Class D amplifier introduced exclusively on the Original d’Atelier, Expert Pro systems are capable of transmitting more power, without any size variation thanks to a 50% increase of the power supply, local decoupling and an increase from 12 to 14 filter inductors per channel, achieving more gain in the ADH loop.

New Power Supply

In addition to reaching 4000W of peak power (formerly 3000W), the new power supply improves the local decoupling from the mains network by 15dB. Load transients are handled 2x faster and their restitution on all frequencies reaches new heights for the ultimate listening experience. The finest textures of your music are revealed.

New Thermal Management

The heat dissipation is 2x faster on Expert Pro Systems thanks to a heat exchange surface muliplied by a 2.5 factor. This allows for better performance during longer listening sessions at high power levels.

Ready for Devialet OS

Thanks to its unique architecture, Expert Pro is capable of integrating hardware and software innovations that will be introduced by Devialet engineers in the future. Among other major improvements, the Expert Pro Line will integrate the new Devialet OS in 2017. A free upgrade will soon open the path for many uses of music such as UPnP/DLNA.

Your Devialet Expert unlike any other

Vinyl turntable, CD player, tuner, computer, smartphone, tablet, NAS, online music services, television : the Expert Pro system elevates all of your music.

The Configurator enables you to adjust, with absolute precision, each setting of your audiophile set up. From defining active sources to setting the specifications of your phono cell, create a system unlike any other in the world.

A unique listening experience, whatever your preferences may be

Regardless of your source and regardless of your speakers, Expert Pro renders your audiophile setup breathtakingly. From the most delicate of turntables, to the highest quality file of your digital library, Expert Pro allows you to rediscover all your music.

Speaker Active Matching SAM®

For the first time, your speakers operate at peak performance levels whilst being perfectly protected.

No speaker models are exactly the same. Expert Pro sends a signal that is precisely adapted to their acoustical architecture. Displacement, driver excursion, acceleration and speed… with the SAM® technology, the Expert Pro system has perfect knowledge of how your speakers behave.

723 speakers can already benefit from the revolutionary SAM technology

The sensoriality of audiophile refinement

A technological gem, the fully omnidirectional Devialet remote enables you to control your installation with the tips of your fingers, with no latency.

An incredible experience.

The Range

The Devialet 130 Pro and the Devialet 230 Pro are the two fully configurable Devialet stereo systems. They incorporate all Devialet audiophile technologies (ADH®, SAM®, AIR®, EVO®, DAC Magic Wire®).

A dual mono Devialet configuration further pushes the envelope of the limits of acoustical engineering: distortion is divided by 4, connections are multiplied by 2, limitless possibilities for evolution, extreme power. The Devialet LE400 and LE800 are the two dual mono systems that provide 400 Watts or 800 Watts per channel.
