Ok, so the question is surrounds practicality of bridged mode vs. stereo in terms of power amps. Does a poeramp run more efficiently in bridged mode or stereo mode? Following this question is a situation: I play in a band where we setup our PA gear most of the time. We need a poweramp for the FOH because we are currently under powering our speakers (500watt speakers) with an amp that only outputs 275 watts stereo. We can easily buy an amp say like a Crown XLS-802, but it seems that you're mostly paying for bridged power vs stereo power. The other solution was to buy two (2) Crown XLS-202's and run them both in bridge mode considering that it will be about $100 cheaper.
