Mike,
There are three 250-watt RMS amps in the base unit, one for each of the PAS segments. One for each section of the tower, and one for the sub. The peak power rating is 1,400-watts based on industry standards.
As for the power and sound quality, I defer to my audiences--they're the ones I must please. Everyone, regardless of audience size, has raved about the system and how wonderful everything sounds. Now the folks in the back of a large hall can hear the same volume and quality as the folks sitting 15 feet in front of the stage. It's a whole new dimension of sound systems available today, and if the Bose cost $3000 I would have still bought it withing blinking an eye. I more than a half century of working with sound systems, there is absolutely nothing that even comes close. And, now that I think of it, I spent nearly as much money on a pair or Barbetta Sona 32-Cs when you include the heavy-duty speaker stands and custom made cables. The difference between the systems was just about $350--big deal. I've spent $350 on high quality mics, and that was years ago. Damned I'm gettin' old!

Cheers,
Gary
