Jeff said: In some ways, buying a Devialet is like replacing your ancient flip phone with an iPhone 6: you won’t believe everything it can do, how it performs every function, and how it looks and feels in your hand while doing it all. It’ll seem kind of like magic. The question is: Are you ready for it? If you’re like me, once you hear the Devialet 400, there will be no going back. I’m as surprised as you that I’m saying this, but the Devialet 400s produced the best sound I’ve ever heard.
