In this passionate quest, we thoroughly reviewed the electronics of our products to develop the new Expert Pro line.
Devialet Expert 440 Pro is a dual-mono amplifier powered by two 440W channels at 6Ω. With half the distortion of stereo, this configuration gives an enhanced power supply to each channel alongside many connectors so even with demanding acoustic structures, the audio will be flawless.
Devialet’s innovations reinvent each step of the acoustic signal path for unprecedented levels of performance. The perfect audiophile playback that is completely transparent offers a rare sensational experience. HD audio can be streamed (wired or wireless) via AIR, DAC Magic Wire or RAM Phono stage. Free, regular updates are available using the EVO platform.
Audiophile Grade Sound
Expert Pro is the flaghship system for audiophiles who demand nothing less than the highest quality available. The Devialet exceeds the performance of an ordinary amplifier by reinventing the combination of audio components for audiophile quality reproduction (i.e. the pre-amplifier, amplifier, DAC, streamer, and phono stage) in a single and extremely thin slab. The Expert Pro has the ability to be configured in thousands of ways to ensure that the audio output signal is as the original artist intended irrespective of the source or speakers.
The Expert Pro systems incorporate all of Devialet’s audiophile technologies, which are protected by 107 patents and hold 58 awards. In addition to these Devialet-exclusive technologies, Expert Pro benefits from many major innovations developed for this new line including ADH (analogue-digital hybrid amplification) Intelligence, Magic Wire DAC, Class A and Class D Amplifier, new power supply and Thermal Management.
Speaker Active Matching
With SAM technology, the Expert Pro system has perfect knowledge of how your speakers behave from the displacement and driver excursion to acceleration and speed. The results of SAM technology means that your speakers will be driven at peak performance levels whilst being perfectly protected. Since as each different speaker model has a different frequency and phase response, the Expert Pro can accounts for these differences and consequently alters the output signal as a function of the architecture of the individual speaker.
The Expert Pro 440 amplifier benefits from triple SHARC 400MHz DSPs as well as one 16 MHz, four 40 MHz and one 64MHz RISC processors.
Expert Pro delivers the best performance ever measured at any power level.
