First of all,are you looking for stereo or surround?I notice in your info that you only have 2 speakers,if so you don't need a reciever at all.Get yourself a nice little integrated amp and that will fill your needs.For stereo that is,for surround things get a little more complicated.If your denon has 5.1 inputs,get yourself a current processor and worry about a power amp later,use your denon for now.That way your processor is a little more modern.I went this route adding an Anthem processor to a Cambridge Audio reciever and the difference was incredible.
So what i am saying is that there are many options,depending on your system and what you want to do with it.
