OVERVIEW
440 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.
EXPERT PRO SERIES
The world’s most advanced audiophile system, Devialet Expert Pro is 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.
