There are a couple of other receivers in that price range which get discussed and used a lot with Axioms. A number of Axiom owners have / had HK AVR 130s, and the ones who have replaced the 130 have tended to stay with HK as they move up. No on-screen display, no pre-amp outs, but very flexible crossover and moderate but sufficent power.
The Pioneer 1014 is a recent arrival here but a couple of people have them and seem to like them. Lots of power, lots of features.
The Denon and HK seem to be happier driving 4 ohm loads if you ever want to move up to M80s or (maybe) VP150. The 150 is 6 ohm so I think most receivers can drive it OK.
If you search the board for each of the receivers you will find some good comments from owners. The best thing seems to be to search for something like :
search string : yamaha 650
search type : AND
etc...
[EDIT] You will find conflicting views here re: whether there is any need to match receiver "sound" to speaker "sound". Consensus seems to be that there is a bit of difference between brands but VERY subtle and probably not enough to be the deciding factor when you buy your receiver.
A bigger question is what kind of listening you are going to be doing (HT vs. music, rock vs. jazz vs. classical, loud vs. moderate etc...). That will help you get more useful feedback, since some receivers (eg. Yamaha) are respected for having great decoders while others (eg. HK) are respected for having great power amps.
I don't want to trivialize what probably seems like a very important decision, but if you're anything like me you're going to end up buying the receiver which has the features you want and looks most like what you think a quality receiver should look like
