I'm guessing there are good tech reasons behind it, but it just doesn't seem to make sense. Has Devialet offered an explanation on this? Just curious.
Actually this is the wrong way around. Assuming sufficient current is available from the power supply, a bridged amplifier can produce 4 times the power of it's stereo equivalent. So a 250 watt amp producing 800 or 1000 watts is possible. However, a 200 / 220 watt amp 'only' doubling to 400 / 440 watts is a little low, and indicates other restrictions. Probably thermal in the case of a Devialet.
Some light reading....
