Devialet Expert 250 Pro with Core Infinity – Flawless Single-Box Audiophile Mastery
- The Definitive All-In-One: Replaces a rack of messy components by combining a world-class DAC, a highly customizable phono stage, a robust network streamer, and a high-current power amplifier into a single 4cm-thin chassis.
- Massive, Effortless Power: Pumps out a conservative 250 Watts per channel into 6 Ohms (and handles tricky 2 Ohm loads down to 340W), giving it the current and headroom to comfortably drive virtually any high-end loudspeaker on the market.
- Core Infinity Board Installed: Fully upgraded with Devialet’s latest Linux-based smart streaming board. Out-of-the-box support for Roon Ready, Apple AirPlay, Spotify Connect, and gapless UPnP streaming.

- SAM® (Speaker Active Matching): Access Devialet’s online database to download a custom mathematical profile tailored precisely to your specific speaker brand and model, delivering tighter bass and total driver protection.
- Bespoke RAM® Phono Stage: Perfect for vinyl lovers. The Record Active Matching stage allows you to configure exact resistance and capacitance parameters on the fly to perfectly suit your MM or MC cartridge.
Visual & Premium Appeal
- Statement Design: Housed in a gorgeous, mirror-polished dark chrome chassis carved from a single block of solid aluminum.
