I would look into a Hafler or a used Bryston. Nothing against the Mackie 1400i because in their price range for a PA amp, they aren't too bad. However, the Mackie 1400 series especially has a very slow reaction that won't give you any punch or ultra clarity and speed. Almost sounds like it has a built in overeasy compressor (and yes I have checked numerous times on the 20 or so Mackie 1400x amps I have used to make sure that the limiter was not engaged).
