My experience has been the opposite of your opposite..:dumbcrazy:I would not say Denon or Onkyo are better than HK, just the opposite.
The reason I generally don't recommend HK is that I've had 2 receivers fail on me. There wasn't anything odd about my setup, lightning didn't strike, etc, but two failed, one taking out my front left and right speakers. :teeth:
It also seems that I've had the suspicion confirmed by someone on this board that repairs electronics for a living. I can't seem to recall who or when, so take that one with a grain of salt.
I don't think that any particular receiver is going to sound "better" than another at a given price point, and agree that it's the feature set and construction that should be examined/reviewed.
As for your system, again, it depends on what you think. Do you think it sounds good? The only item I think I can unequivacally say I'd change is the sub. SVS or Hsu are going to give you a better bang for your buck than just about any brick&mortar store.
