I wonder why it is the lonely duck?
Can someone help me understand this slight on the wonderful Le250?
cheers

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
