440 Pro from Devialet
440 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. 440 pro is the audiophile system for the most discerning of music lovers.
Well above and beyond an ordinary amplifier, Devialet reinvents and combines for the first time all of the key components of expert playback (preamplifier, amplifier, DAC, streamer, phono stage) in a single and extremely thin slab. Devialet technologies reinvent each step of the musical signal chain for never before achieved levels of performance.
Pure sound. Explosive dynamics. Absolute silence. Perfect audiophile playback, completely transparent. A rare emotional experience.
