NAD 320/325BEE, Cambridge Audio Azur 540A, other ideas???

I'm looking to upgrade my current system and I am searching for insight to find the best match for my components. Out of high regard for TAS' opinion and research, I bought the Oppo HD970 as my universal player. I also own a pair of Klipsch RF-62 speakers. I am pleased so far with these two components, but the Denon receiver I am running them through is incompatible with the sound I am searching for. The Klipsch's are very revealing speakers, and can be quite forward in the treble, as well as boomy in bass. I would like a 2 channel amplifier that will warm my system and give it a more refined, laidback sound; with excellent midrange detail. I certainly do not want to purchase any components that will further obviate my Klipsch's favor of bass and forward presentation. I do not have many hi-fi stores in my area, so I am needing some thoughtful advice. So far, I have narrowed my focus to the CA Azur 540A in addition to the NAD 320/325BEE. Would anyone be able to help me? I would certainly appreciate your advice.
