So the consensus is, for volume levels below "risk of long term hearing loss" I won't hear a difference between what the Denon can pump out and what the Denon+Amp can pump out to the M80's and I'll have plenty of extra room.
For example, I read a review for the DVD-A disk of the 1812 Overture. It warned of speakers not being able to handle the sudden volume change that accompanies the cannon fire. If I pair the M80's with a Denon 33xx/43xx receiver I won't have to worry about things like that correct?
M22's x 3, QS8's x 4 SVS PC12-Plus, Denon 3311ci Ear-to-ear grin? Priceless!

I think my next receiver will be a Denon $1k+ because it seems to have more options built in than the Pioneers do.

Reading a Denon manual and understanding it are two wholly separate things. I'll probably never own a Denon, but I'm tempted to give their manual a shot, just to see if it really is as bad as everyone makes it out to to be. Perhaps then I could be a little more helpful in Denon related threads too. But for now I have datasheets, and reference implementations for HDMI 1.4 chipsets to read up on. Denon manuals aren't as bad as they are made out to be. They have the information you need, but you have to know how to interpret it. Much like any code book. Like the NEC, you need the guide book to go along with it. Unfortunately, Denon doesn't supply a guide book, but batpig has done well his. As to the OP's original question, you don't NEED the outboard amp. It's a matter of WANT. I would pass on the Emo stuff though, if you really WANT an amp.

Correct. Using this calculator we see that at 100Db average volume with 10 Db of head room the M80s will use 198 W of power. Note this is using Axiom's in room response of 95 db to account for room gain. I believe that the 43ll you were looking at will deliver this quite easily into 4 Ohms. Turn that down to a much more reasonable but still loud level of 85 db and you are using 6 watts. Give yourself 20 Db of headroom that may be demanded by the most dynamic of classical recordings (like the 1812 Oveture??) and you are using a whopping 62 watts peak. That means your 4311 will have around 140 watts in reserve that you will never use unless you move your system into a much bigger room. I don't know why people so happily ignore simple physics in their quest to spend thousands of dollars on amplification that, as John always points out, will not be used.

Scamp, keep in mind that if it's an older CD (like, when the format was just emerging), sometimes those "warnings" were put on the discs as a marketing point. What early adopter could resist a warning that the recording was "so real, and so dynamic, that you have to be careful with it"?
I have a Billy Cobham CD like that....

Fredk:
That's exactly what I was looking for, err... Had I know what I needed to be looking for. Much thanks.
Physics. It works Bitches!

If you don't have to have all the latest bells and whistles, they are blowing out the Pioneer SC-27 (it is now last years model) for less than $1000 U.S. Just a heads up for anyone looking for a good deal on a pretty powerful receiver.
I picked one up recently and I like it very much. It has the 140 watt Class D amps and drives my M80's very well. It seems to have a lot of dynamic power on tap, it never seems to run out of steam.
The latest Denon's do have a lot more bells and whistles though.
