Thanks for the input. I was really wondering if the physics of sound waves would show that if I compromised the sound from a centralized listening point, and changed speaker positioning to decentralize as well, then while that one spot would suffer, but everyone else's listening experience would get better.
Like for instance, what if I pointed the L/R fronts so that instead of pointing directly at the optimal seat, they pointed just to the opposite sides of it? The sound from both speakers would still get to that seat, but the sound waves would cross in front, making it more likely that the side seats would hear the opposite side fronts better. I don't know if that makes any sense. Again, I am not an audiophile, but I'd prefer better listening for the entire room than for a single seat. It just seems like every one talking about optimizing their HT is optimizing it for a very acute listening area. No one is talking about optimizing it for the entire listening area.
Oh, and about the AVR, it's a HK 254, so it doesn't have Audyssey, but something similar. And I for sure will run it.
