Can you give us more details as to your room size, speakers, listening habits, etc.? You may find your Denon is more than adequate in the power category. I have a very large room 31ft x 30ft x 9ft ceilings, so adding powerful amp has helped me with being able to fill the room at louder levels with no clipping or distortion. If you have an average to smaller room, your Denon most likely would be fine, unless you like listening at very loud levels.
