Goodbye to Devialet - after upgrade program

[Axel]

I would have to agree with Guillaume.  I recall talking to Mathieu Pernot shortly after the launch of the D400.  I asked which was best, the D250 (Which Mathieu knew I owned) or the D400.  I kind of expected Mathieu to be diplomatic about my lovely (and very expensive) D250, but no, his answer was direct, the D400 is better because the dual mono allows much lower distortion.

As for power, a while back I would have agreed with the view that beyond a sensible limit, power is not important.  However, during the 1000 Pro launch Mathieu Pernot explained for about half an hour why in fact it was the most important thing (Ian G posted about this in the 1000 Pro launch thread.)  It is an interesting topic, and far more complex than you might first think, but for sure there is a lot more to this subject than looking at the back of your speakers and seeing the little maximum power label and comparing this with the amplifier power.

I agree here: power is important. 
What I got when I added a 200 companion, was a sense that the amps exerted more grip and control to the bottom end in particular. Bass notes seemed to start and stop with more definition, with no hangover or flap.
