Product Description

This expertly matched package merges two of the very finest hifi components we've ever heard in our showroom; KEF Blade and Devialet Expert 440 Pro to create the ultimate system for committed audiophiles who want nothing less than the best.

KEF Blade

KEF Blade speakers aim to perfect a revolutionary concept and are the world's first single apparent source loudspeaker with impressive sonic capabilities. Featuring a modern architecture that achieves the ideal point source, the KEF Blade's four complex 9" bass drivers are configured to occupy exactly the same point in space as the Uni-Q HF/MF array so the sound appears to emanate from a single seamlessly coherent source.

Devialet Expert 440

Devialet Expert 440 Pro is a dual-mono amplifier powered by two 440W channels at 6Ω. With half the distortion of stereo, this configuration gives an enhanced power supply to each channel alongside many connectors so even with demanding acoustic structures, the audio will be flawless.
