DEVIALET Expert Pro 220 – The ultimate audiophile system


The best of both worlds. Our pioneering hybrid amplification technology combines all the linearity and sophistication of Analog (Class A)
with all the power and compactness of digital (Class D). Working in parallel, they deliver unbeatable performance. At every turn.

SAM® Speaker Active Matching works by recognizing the exact specs of your speakers. So Expert Pro can tailor the sound signal to fit their precise requirements. In real time. A major audio breakthrough, SAM lets your system achieve perfect temporal alignment between the recorded signal and the acoustic pressure generated by your loudspeakers. For the first time ever.

Pure emotion. Extreme fidelity. All your music, just as the artist intended.

Take the shortest route. Invented by Devialet, Magic Wire® dramatically reduces the distance between DAC and speaker output. Right down to 5 cm. A world record. Designed to keep external threats to the sound signal to an absolute minimum.
