Thanks again for everyones input. I've spent the better part of a few hours playing around and got great results. I do feel like an idiot as I should have known better, and should have done this months ago.

I started by setting the M60s and VP150 to small and setting my crossover to 60hz. As you can see in the pictures the main 3 speakers are in a bit of an alcove. I pulled my towers forward so that they were at the opening of the alcove,and toed them in a bit to help disperse the sound into the room instead of straight out.
Then I increased the output to the QS8s.

All of these things seemed to have helped open up the sound field immensely. The volume level is down to between -32/-26 now and the sound field does seem much much wider and full. All without the ear fatigue that I had experienced with the Klipsch.
I'm going to play around a little bit more, but as it stands, I feel like my speakers just got 10x better. As much as I liked the convenience of the Yamaha speaker set up, it seemed to really limit what the settings should have been set to.
Thanks again for everybodies help and input.
