My problem with active speaker designs is that they are not user serviceable after the warranty runs out. You cannot adapt the sound of the Speakers to your own taste either.
Plate Amplifiers won't last twenty years without dying to my knowledge. Just look at all the great Subwoofers form 20 to 25 years ago. The plate Amps are dead and a swap in from Parts Express doesn't work or fit all the time. Will the manufacturer even support repairs should it fail ?
Stick with separates unless you are on a tight budget or with a manufacturer who'll support an out of warranty dead Amplifier after many years of service.
