Devialet 140 Expert Pro

I can’t help feeling that Devialet’s biggest concern with the Expert Pro in all its guises is nothing to do with the performance. It is, in microcosm, an existential crisis endemic to the audio business entire: the lack of new blood. I suspect practically everyone who wanted a Devialet... has one by now, and the number of new people coming along to buy a new Expert 140 Pro is dwindling. Sure, Devialet has got this covered with the Phantom, but I’m not sure if there will be many converts from Phantom to Expert in reality. Core Infinity is an outstanding step-change for Devialet, but I can’t help but think most people who will get to hear it will do so on an Expert model they may have bought half a decade ago. And if Devialet can’t get new people buying its product, who can?  

I don’t want to end on a down note because that’s not what the Expert 140 Pro deserves. This is an exciting product, made all the more exciting by the Core Infinity updates. Devialet has made a huge change to its product in the shape of Core Infinity, and it makes the amplifier lead the field in detail retrieval and precision once more. Existing Export owners should make sure their system isn’t pitched into brightness before committing to an upgrade, because they will find the amount of detail on offer an intense experience. But, many will make the change, and make changes to the system because that’s how good the Expert 140 Pro really is.
