Expert 210 Pro Dual is the base-level Dual-Mono configuration in the Devialet Expert Pro range.

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 two, and an increased power reserve of 210 Watts for each channel.



Expert 210 Pro Dual

210 is the base-level Dual-Mono configuration in the Devialet Expert Pro range.

Delivering 2x 210 Watts of power under 6Ω, the prowess and quality of proper Dual-Mono amplification is finally accessible via two Expert 140 Pro units in linked configuration.

So why is the output power not double? The ideal situation is to have no limitation in terms of thermal dissipation and current availability, however With the class D board of the 140 Pro limits the current availability in this case, and therefore the output power can only multiplied by 1.5.

More information



Devialet was born in 2007 as a response to the paradox that whilst music has never been so accessible in terms of volume, the quality of the sound itself, and the way technologies manage to restitute it, remains questionable. The purity and detail that make music what it is, continues to elude us.

The company name is a reference to engineer Guillaume Vialet, a companion of Diderot and contributor to the French Encyclopedia. Vialet is widely known as one the intellectuals who, through their intellectual, cultural and scientific commitment, contributed to the betterment of the world.
