Just to clarify, you've bought the Denon but not the speakers yet? Sorry if this seems like a daft question, but quite a lot of people come and post what they've bought, and then ask if it will be any good (maybe they want some assurance to assuage their buyer's remorse?) which seems a little too late. If you have bought both the Denon and the speakers, have a listen to them, give them some good time to run in and for you to get used to the new system, then tell us how it is (and if you don't like it, I'm sure people will have suggestions to remedy your problem).
On paper they should be decent match. You might get lucky and get a reply from someone who has heard this specific combination
