Just one final response to wrap it up from my side. I think Manoet is right in his post in the suggestion box, we're going very off topic here. 
Unfortunately we're really missing the detailed specs here. The P3 for example can supply up to 9200W of short term peak power (P=V*I, 9200=230V*40A) we however don't know for how long. The tightly digitally controlled power supply inside the Devialet could use up to 3000W in peaks, again we don't know for how long. I'm also not sure under what real world conditions this may happen but I don't feel it'll happen at every kickdrum at volume levels that are just tolerable. But of course I don't have the numbers and measurements so I could be wrong and of course it is system dependent as some loudspeakers are easier loads than others. "Mitigating factors' to prevent current starvation is the power storage inside the Devialets (13.200μF of capacitance) but I suppose the possible energy reserves inside the P3 are already taken into account in the mentioned 40A.
Fortunately I have never noticed a shortage of power/restriction of dynamics but my situation is even more difficult than just described as I also use an active subwoofer which of course also has it's own internal power storage reserves. And finally my Devialet has a 2nd order high pass filter active @ 80Hz so doesn't have to work as hard in the lower frequencies compared to a setup without an active sub.
