I have a pair of f228be that I bought a little over a month ago that I use in a combined 2 channel + HT system. In my case I use an integrated amp for 2 channel listening via vinyl, tuner, CD or streaming. The integrated amp uses home theater passthrough to run the fronts for HT use.
I chose this approach not so much for improved sound quality as just for personal preference. Something about the integrated amp is more satisfying to me (maybe just 'prettier' or 'more fun') for 2 channel listening than the AVR, and my use is much more 2 channel than HT. My AVR is the least expensive one I could find with front preamp out and 12v trigger which were necessary for HT passthrough use. Your Denon has both of these so it would work for HT passthrough if you were to consider going this route.
You mentioned liking to play at higher volumes sometimes. FWIW, I usually listen at around 70 dB (as measured with SPL meter on phone from listening position), and according to the meters on my integrated amp this is about 2 watts at peaks, and well below 1 watt most of the time.
Of course there are plenty of good reasons to just use an AVR for both music and HT. Easier sub integration and room correction / DSP probably being the biggest advantages. But, if you are like me and prefer a dedicated two channel setup for music, HT passthrough is a nice seamless way to achieve it.
