Additional information


The prowess of Dual-Mono amplification finally accessible.

The Expert 210 Pro combines two Expert 140 Pro units and lets you soar to whole new levels of performance, with a distortion rate divided by 2 and an increased power reserve for each channel.

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. By rethinking sound reproduction at every turn, Devialet engineers have been able to achieve the best performance ever measured, at all power levels. With a precise and natural attack, explosive dynamics, naked silence and beautifully true timbre, the experience is breath-taking.

Entirely configurable and upgradable, Expert Pro reveals your music’s full potential, whatever the source or speakers.
