I'm running a pair of m 80's and a vp 150 center off an Onkyo 787 receiver and for movies it was fine.for music at louder levels the m 80's were triping the auto-protect off and the receiver would shut it's self down.this was not at ear blistering levels but louder than h/t.so I ended up buying a seperate amp and now everything is music bliss.I've also noticed that my center and rears sound more dynamic possibly from freeing up some power from the front two channels.I like the Onkyo for the features for the money and I absolutly love the m 80's but despite what some people will post on these boards stateing that the m80's will do fine with an a/v receiver I'm here to tell you it just 'aint gonna happen.well you'll probably be allright if you pick up the $3500.00 dennon but for that kinda green I would go for the seperates.
