What are you really going to learn from a "review" of an amplifier? Any good quality amp should be transparent, they do not affect or change the sound, and someone who has just got one can't know how long it's going to last (or how good the quality is).
For things like this you just have go by the company's reputation, and DD/AQ has a great one.
That amp does 1200w. According to DJ from audioque it is slightly underrated but not much.
Which makes perfect sense when you consider: the 1200d is built on the same board as a hifonics 1606d, but obviously uses better quality components. Hifonics claims 1600w for that amp, and they are know to be ~20% overrated so ~1250w for that amp.
