Devialet Expert 440 Pro Dual Streaming Amp Chrome Black

When Devialet entered the hi-fi world with the D premiere over 10 years ago, the innovative technology and fascinating design of the French amplifier represented a real revolution. And this still applies to the successor models of the Devialet EXPERT series PRO - thanks to constant further development, Devialet has always managed to be (at least) one step ahead of the competition.

With the two-part Devialet EXPERT 440 PRO, Devialet is taking a huge step towards the ultimate high-end. The real dual-mono architecture completely separates the amplification of the two channels from each other and thus enables even lower distortion, even more power and, above all, even better sound. This is where the ADHV2® hybrid amplifier technology can show its advantages even more impressively.

Of course, the Devialet EXPERT 440 PRO also has the SAM® speaker management system and can therefore be optimally adapted to each loudspeaker. The developers at Devialet record the properties of numerous loudspeakers from different manufacturers in a constantly growing loudspeaker database. The resulting speaker profiles and all other settings can be conveniently set up in an online configurator and transferred to the device on an SD card.

With the Devialet EXPERT 440 PRO, Devialet also uses its own converter technology called DAC Magic Wire®. This is integrated into the infrastructure of the device in such a way that the distance between the D / A converter and the loudspeaker connections is a mere record-breaking 5 cm. This means that there is no chance of damaging influences on the sensitive analog signal.

The connections of the Devialet EXPERT 440 PRO correspond in scope and quality to the Devialet EXPERT 220 PRO. This also applies to the integrated high-quality phono pre-stage, which can be matched extremely precisely to the pickup used. The Devialet EXPERT 440 PRO receives music data via LAN cable or wirelessly via WLAN, and Devialet has its own app to control streaming. Everyday operation is via what is currently perhaps the most beautiful remote control in the industry. In addition, the Devialet EXPERT 440 PRO can be connected to up to 8 other Devialet devices via the network.

Like all devices in the Devialet EXPERT series, the Devialet EXPERT 440 PRO is based on the Evo® platform from Devialet and can thus be adapted to future technical developments, new standards or formats via software updates.
