joerod,
Joe, there's no question you have a reference theater which some of us would drool to have so I have no doubt your speakers do a fantastic job for you

What I think some people bottom line really are asking is how well this will work with tall speakers, more like full towers or in my case, planars & electrostats. Can you possibly set up such an evaluation in your HT?
Given that my fronts are 6 ft tall, I'm skeptical (or at least don't have any idea) how much difference I'll hear with 2 small sats for heights with only 2.5 ft clearance above the fronts to work with.
I'm glad you gave heights a good review, since the 3 published reviews I've read so far are not as favorable. This means there's "hope" that it can make a difference. We need more owners to chime in here.
And on that note, I'm actually quite surprised not one person in the Denon 4310 thread and not many Onkyo posters are commenting on it at all. Believe me, I'm asking. And it's crickets

I really appreciate you taking the time to let us know your experience with it, because almost no one else is. And I trust your experience in a real world HT rather than some arranged demo using games

No offense to Dolby, but movies is the NO.1 primary interest not people playing shooter games on their HT's.
In addition to concerts, I'd like to know how it helps or hurts various music recordings and some other effects-laden movies.
Thanks much for all your contributions. You are indeed cutting edge, man
