The D250 and the D250Pro are both limited by the maximum voltage the Amp can deliver (slightly below 40 Volt per channel - if bridged it can deliver nearly 80 Volt)
=> 40 V are leading to about 266 W in 6 Ohm
=> 80 V are leading to about 1066 W in 6 Ohm
These values are the same for the D200 and the D220PRO but they are artificially limited to about 35 V for the D200 and about 36.5 V for the D220 to take into account their limited heat sinks.
The heat sinks of a D250 is limiting by about 800 W; the D250Pro is now optimized to handle up to 1000 W
