For my Synchrony's, which are 4 ohm speakers, the XPA-3 delivers 300 Watts RMS per channel. I would call that power to spare. The XPA-3 is neutral-sounding (which is good), and has been reliable and trouble-free since I purchased it over a year ago. And driven hard, it barely gets warm to the touch. In summary, I like it a lot, and recommend it highly.
