I was in a similar situation, wanting to double-duty my audio system for 2-channel listening and H/T. I also have a Denon AVR (X-4000). Because my main speakers are Magnepan MMGs that require more power than the Denon has to adequately drive them, I added a separate power amp (B&K EX-442 Sonata at 350 wpc/4 ohm) AND preamp with H/T bypass (Parasound P5). I also have a powered sub (Rythmik F12G).
The integrated setup you’re considering would combine my two separates (amp/preamp) into a single unit. Not sure of the ultimate sound of what you might end up with, but I’m exceedingly happy with the performance of the system I put together for the money that’s into it. The Key to the Kingdom for a sound system to do double duty is a H/T bypass feature.
On a strange side note, when I’m passing through my preamp with it powered on and the bypass engaged, the system sounds better than if I pass my signal through it when it’s powered off, as it will pass the signal either way. I get some measure of signal bump, so it’s always on - which is where you’d be with an integrated any way. I expect my next move might be an integrated, if I can find something that matches the B&K/Parasound output I’m getting now.
