I also don't think it's the 10% increased steady long term maximum output power but rather the way power is delivered: faster load transients with higher peak power and lower losses.

For me the improvement is due to the loss of the Power-Filter-Board as it was a Riser-Board with this tiny pins to connect to the power supply. All the power through just some of this pins? No way to get enough juice through for the amp. Easy to improve...and they did. The same with the tiny filter elements in the IEC. Way too small for high currents. So they now build it on their own and use bigger electronic components (see Antoine's system pics with open 250PRO). Easy too. That's it (mostly) for the power.
