I agree, Devialet's choice of the words 'at least' are a mistake and the word 'maximum' should have been used: At its rated output and their stated 85% power supply efficiency, the D250 consumes 588 watts RMS into 6 ohms (250wpcx2ch)/.85 and 889 watts RMS into 4 ohm loads (378x2)/.85. If one assumes +6db of dynamic headroom (6-9 db is typical in high end SS amplifiers) the peak power requirement is between 2352 watts (6 db headroom) to 4704 watts (9 db headroom) depending on the design of the power supply and the ADH amplifier.
So Devialet's assertions are far from cow dung.
For me music is all about the dynamics! So if one ignores the real world power requirements of your amplifiers (and other components), you do so at your own peril. In this case it is never about the RMS power. It is about the peaks.
I was off this thread branch, but misunderstandings are rampant.
