A low-profile design with plenty of power
The Devialet Expert 140 Pro Stereo is a minimalist audiophile's dream. Its sleek low-profile chassis — just over an inch and a half tall — generates an impressive 140 watts per channel, plenty to drive the most demanding speakers. Proprietary technology, clever amplifier design, and flexible user interface software make it a unique centerpiece for a top-notch two-channel setup.
Hybrid amplifier technology
ADH® combines Class A and Class D amplification technology for distortion-free performance at all power levels. Signal passes through a Class A voltage amplifier to reduce distortion, then on to a Class D current amplifier designed for high gain. Devialet's engineers also made sure heat dissipates quickly, so you can listen louder and longer.
Smart setup with the configurator
Devialet's online setup utility is called the configurator. It allows you to create up to three system configurations, save them on the included SD card, and upload them to your machine. It's a fun interactive tool that lets you dial in cartridge loading for the phono preamp, custom crossover filters for specific speakers, and other vital settings.
One of the coolest options is the ability to configure AXD®, Devialet's proprietary digital signal processing technology. The company partnered with some of the world's best-known speaker manufacturers to create an exciting feature known as SAM® (Speaker Active Matching). SAM uses active crossover filtering to tailor the receiver's signal to match brand-specific speaker profiles, for maximum performance.
Phono settings can be similarly specific, with pre-loaded profiles for most cartridges, listed by brand and model.
Convenient connections
The 140 Pro is compact, but it doesn't skimp on inputs. There's a Toslink digital optical input, and two dedicated S/PDIF digital coaxial inputs. If that's not enough, the inputs for the phono stage an also double as a pair of additional coaxial digital inputs, or as an analog RCA stereo line input. If you store high-res files on your computer, the Type-B USB input on the back panel will let you connect that, too.
Speakers can be connected via a pair of binding posts that also accept banana plugs.
