Instead of addition (1+1=2) it might be more accurately seen as division: the specifications of a single Devialet are divided either between two speakers with a D200/D250 or just one speaker with dual-mono D400/D800.
When driving only one speaker (dual-mono) the power can double (or more) but there are also many other benefits. Channel separation (and thus soundstage, imaging, etc.) is improved since the entire unit is driving one channel (left or right) rather than both. The DAC can use its multiple channels to reduce distortion rather than drive multiple channels. The entire signal chain is focused to one channel, and thus improved.
At least that's one way of seeing it. Hearing the difference is a much better metric, so read the above threads or audition one for yourself.
