Enquire about this product

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

This Expert Pro 440 is unlike any other: set each of the thousands of possible configurations for a unique musical experience.

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.

Key technical outsputs include: 
THD+N : 0,00025% (440W / 6ohms)
THD : 0,0001% (10W / 6Ω)
Signal-to-Noise ratio: 133dB
Advanced Phono stage
New ADH Intelligence®

Unmatched performance
Devialet technologies reinvent each step of the musical signal chain for never before achieved levels of performance. Pure sound. Explosive dynamics. Absolute silence. Perfect audiophile playback, completely transparent. A rare emotional experience. The performance delivered by Expert Pro 440 is the best ever measured, at all power levels.

Your Expert Pro 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.

Ready for Devialet OS
Thanks to their unique architecture, Expert Pro systems are capable of integrating hardware and software innovations that will be introduced by Devialet engineers in the future.

Among other major improvements, Expert Pro will be able to integrate the new Devialet OS in 2017. A free upgrade will soon open the path for many uses of dematerialised music such as UPnP/DLNA.

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.

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.
