I upgraded to Expert Pro with Core Infinity, and my key impressions are: greater transparency; superior timing; fantastic imaging, both laterally and in relation to depth.

Operationally the Expert remains a pleasure to use and to own; both AIR and Core Infinity appear stable and the sound quality is consistently superb.

Devialet, in my view, continues to redefine the audio state of the art - and with a delightful domestic appearance.
