Audio Science Review of Expert 200.

Well, perhaps there's more to the story? Devialet: "We'll repair it at no charge, just sign this NDA...".

There is perhaps a lesson to be learnt here.  If at some time in the future someone has on old out of warranty Pro model that appears to be developing a fault, just send it to Amir for testing, he will break it, you will then get it back repaired for free by Devialet.  Something to keep in mind.
