@erik_squires , i could be wrong about this. But, i sense that when a native mixed DTS X or Dolby Atmos movie track is downmixed by a receiver to 7.1 or 5.1 because a user had fewer speakers, dialogue can lose intelligibility. Same goes for a native mixed 7.1 track downmixed to 5.1 by a receiver because the user had fewer speakers and so on.... This is quite possibly a limitation/inaccuracies in downmixing algorithms. Some manufacturers do better than others. I sense that Yamaha currently seems to have a slight edge on this from comparisons i have made with different receivers. Pioneers & Denons seem to do worse!
Why don’t you give this Uni-fi 2.0 center channel with the concentric driver a shot? Elac just released this model (a week ago) with the "trickled down" mid/tweeter from the more expensive Adante series.

I paid 1500 for the Adante center channel and 200 for a dedicated stand back then. This is a really good price ($399) on the Uni-fi 2.0 for the same performance pretty much. You may want to factor in the cost of a dedicated stand as well.
