Devialet Astra integrated amplifier features a built-in digital-to-analog converter and streamer, and has a full set of inputs (coaxial and optical digital inputs, USB-C, MM/MC phonostage, line inputs, Ethernet and Wi-Fi). Devialet Astra is based on the iMX8 processor and a new version of Devialet Operating System, DOS3 with new Configurator system and offers Devialet’s proprietary amplification ADH technology (Class A and Class D combination), offering the widest frequency range possible. A Speaker Active Matching (SAM) module is also on board, as is the company’s new RAM technology, which allows dynamic equalizer adjustments based on the characteristics of your turntable and adapting the phono stage for optimal performance.
