Expert Pro sound quality

[Antoine]

Nothing yet.

Yeah Hermans sounded convincing enough (to perhaps be from inside Devialet?).

But if you can extract 200w extra in dual mono after a complete revamp of case heat sink and major electronics, surely the single box would at least benefit in some way?

I also asked them if the still consider it a current model (in that it's not on their website).

Perhaps it's Devialet inside information or perhaps these values are printed on the PCB's. We really don't know and should ask him.

Most probable explanation on your question: the previous limit (before Pro) in dual mono was a thermal limit, the limit in the single box is a electrical limit. We can also conclude from all this that the dual mono Pro models at 1000W@6Ohm per amp are now also on/very near the electrical limits.
