Devialet Expert 440 Pro Dual Amplifier

Description

Expert 440 Pro Dual

The Expert 440 Pro Dual amplifier is the mid-level Dual-Mono configuration in the Devialet Expert Pro range.

Expert 440 Pro combines two Expert 220 Pro units and offers up to 16 physical inputs and 440W of power per channel, for a Dual-Mono set-up without any compromise.

So why is the output power not always double? The ideal situation is to have no limitation in terms of thermal dissipation and current availability, however with the 220 Pro, the casing is limited by thermal dissipation in dual-mono mode and therefore the output power is only multiplied by 2.

Brand

Devialet

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.
