QSC GXD 8 4500-Watt Amplifier with Built-In Processor
for the price, usually around £650, you get 1200 watts per channel into 4 ohms. The build quality seems very good, the performance is excellent, and they'll happily drive a single E18SW (800W rms) per channel to high output levels. I have now used these for a number of events in the last couple of years and they have performed flawlessly. The built in DSP is very capable, and useful if you have more than one type of speaker in use. Being switch-mode, they're light, which is nice when you have seven of them in a flightcase. They seem to be built to a slightly better standard than the GXD4 - one of which I've had fail.
The only negative thing I can think of is that they lack air filters behind the grilles so after a summer of events they become quite dusty inside. Routine maintenance should include taking the lids off and cleaning them every so often.
