Description
Every Expert 250 Pro input is configurable, meaning an unlimited amount of settings at your disposal, whether they be analogue inputs, digital inputs or outputs of either kind, the Expert 250 Pro adapts to your needs.
The built-in EVO card enables free, regular updates of the internal software that offer you the ability to improve the performance of your Devialet or to take advantage of new features in just a few clicks.
The 250 Pro comes with the latest Core Infinity firmware, which allows you to stream from the Devialet in a number of ways whether it be by Airplay, UPnP or via Roon. This means you are able to stream with ease from services like iTunes, Spotify, Tidal and Qobuz.
Like all Expert devices, the 250 Pro is fully controlled by software that allows you to configure it via their online configuration tool. Customise each of your inputs according to the sound source to achieve the best possible results.
On its own, the Devialet 250 Pro is an exceptional stereo system but it can also be upgraded at a later date by adding another 250 Pro and creating the flagship dual-mono 1000 Pro system.
