Devialet Expert 440 Pro Dual

Exceptional architecture and performance.
Manufacturer: Devialet
Manufacturer part number: Devialet Expert Pro 440 Dual
£13,400.00

The Dual-Mono Expert Pro configuration is able to achieve new heights in performance, in particular with a distortion divided by 2 compared to the stereo system, more power for each channel and an extreme variety of connectors for the most demanding acoustic architectures.

The Expert 440 Pro loads all Devialet exclusive technologies as well as major innovations developed for the new Expert Pro range.

Well above and beyond an ordinary amplifier, Devialet reinvents and combines all of the key components of an audiophile system (preamplifier, amplifier, DAC, streamer, phono stage) into a single and extremely thin slab.

A dual-mono Expert Pro configuration further pushes the envelope of the limits of acoustical engineering: distortion is divided by 2, connections are multiplied by 2, limitless possibilities for evolution, extreme power. Two systems that provide 2x440W or 2x1000W.
