Just to add to the topic of the original question, in my experience Meridian speakers integrate best with each other when of the same type. My priority would be to use the same across the front, then from front to rear.

This may matter less with DSP8000’s/DSP7200’s, but it does seem to matter with their smaller speakers. I found the tonal difference quite noticeable when I had a Meridian surround system.
