You didn't state what your goal is, or how you intend to use your system. In a nut shell, if your system will be used more for theater, a good quality receiver such as the Denon you refer to would be a very good choice. In fact, it would be a good choice for anchoring a music reproduction system as well. I wouldn't suggest separates or external amplification unless you're really serious about music reproduction, and will be using your system far more in this role than in a theater role strictly because of the cost factor involved. In my particular application, my ratio of music vs theater is probably 90% or more for music, and the remaining few percent for theater. This is why my home theater set-up is drastically lopsided in favor of audio reproduction vs video. Not only do I use my receiver like most people do, but I also use it as a pre-amp for several (basically 8 mono-block & 3 LFE sub) amps which power additional speakers within each channel. Obviously this setup is drastic overkill for theater, but sounds exceptional for music reproduction. So use your goal or intended use to determine how far you should go on the audio side.
