About the Expert 250 Pro

The Devialet Expert 250 Pro is designed to replace traditional Hi-Fi systems by integrating all core playback elements—preamp, amplifier, DAC, streamer, and advanced MM/MC phono stage—into one compact and elegant unit. It features a hand-polished casing carved from a single aluminum block with a 100% pure copper bottom plate for optimal thermal dissipation. The amplifier delivers 2 x 250 Watts RMS under 6Ω with ultra-low distortion (0.0005% THD+N at full power) and a high signal-to-noise ratio of 130 dB. It supports a wide range of digital inputs including USB Audio 2.0 asynchronous, 4x RCA S/PDIF, optical TOSLINK, and mini TOSLINK, as well as analog inputs with adjustable sensitivity. Streaming services supported include Roon Ready, UPnP, AirPlay®, and Spotify Connect. The system is fully configurable and upgradable, with daisy chaining capability for up to 8 units. It incorporates Devialet's exclusive technologies such as ADH®, SAM®, RAM®, AIR®, EVO®, DAC Magic Wire®, and Core Infinity, ensuring precise, natural attack, explosive dynamics, and true timbre. Dimensions are 400 x 400 x 40 mm, and it weighs approximately 9.7 kg.
