Naw, Charles; no Denon, including your 3300, clips at a number below its power rating unless it's defective. At the rated number all receivers have distortion below audibility and are nowhere near clipping.
I see your "Naw" and raise you one HT Labs Measurement from Home Theater Magazine, November 1999. Maybe they don't mean clipping, I don't know. But it explains (to me) why my experience with more clean power has not jived with your knowledge of the controlling equations. I could have misunderstood it, no doubt about that.
