The Devialet Expert 220 Pro Core Infinity is a high-end integrated amplifier with built-in DAC, phono stage, and streaming capabilities, based on Devialet's ADH hybrid amplification architecture. It delivers 2 x 220 W RMS into 6 Ohms with ultra-low distortion (0.0005% THD+N at full power, 0.00025% at 10 W) and an exceptionally high signal-to-noise ratio of 130 dB, ensuring highly transparent and dynamic playback. Exclusive Devialet technologies include ADH, SAM, RAM, AIR, EVO, and DAC Magic Wire, combining advanced amplification, speaker optimization, and digital processing for precise control, very low output impedance (0.001 Ohm), and a damping factor of 8000. The Core Infinity streaming board adds modern network and streaming support and runs Devialet OS on a Quad-core ARM 1 GHz CPU with 1 GB DDR3 RAM, 4 GB Flash, FPGA-based optimized audio routing, a second DSP, and multiple asynchronous sample-rate converters. Connectivity includes Ethernet (100/1000 Mbps), dual-band Wi-Fi (2.4/5 GHz 802.11ac), USB Audio 2.0 asynchronous, multiple digital inputs (coaxial, optical, AES/EBU), and configurable analog RCA inputs including an advanced MM/MC phono stage. The chassis measures 383 x 383 x 40 mm and weighs 5.9 kg, with premium metal construction and a dark metallic finish.
