One unit, many functions. That’s the seduction of the 21st century’s integrated amplifier. Adding DAC and/or phono stage to amplification casts a powerful spell. Side effects may include lower box count; fewer interconnects; fewer power cords; tidiness. French company Devialet have taken this concept to the next level with their Expert series of amplifiers which, stop sign alert, are so much more than just amplifiers. The €6’990 Expert 200 wants for nothing but a headphone socket. Everything else is taken care of within. Just add loudspeakers and maybe a turntable. The multiple personalities of our mirrored box don’t arrive from hardware module options à la Vinnie Rossi’s LIO. They live in software. The Expert series’ operating system dubbed EVO is our first example of this manufacturer’s unabashed love affair with three-letter abbreviations. (Stand by still for SAM, ADH, RAM and AIR). EVO runs on an Analog Devices SHARC chip and is field upgradeable. It talks to your local network via Ethernet or WiFi.
