“As to how the Expert 1000 Pro stacks up against other Devialet models, I can say without hesitation that it’s better -- but not night-and-day better. It’s a refinement of the Devialet sound, not a departure from it or a great leap forward. The last-generation Devialets I’ve heard -- the 120, the 200, and the 400 -- are still super products. The Expert 1000 Pro is just a little bit better in ways that might mean more to some listeners than to others.”
