Thank you both for excellent points.
I appreciate the point about esthetics being enough of a reason for upgrade. I think that is really what is driving me more than improving on the performance.

Based on what I am reading the M5HP would be a very nice set of mains on the wall beside my TV. The center speaker may be an interesting decision as I love the look of the VP180 but if it overshadows the M5HP then I might have to see if I can audition it first.
Again, thank you so much for your input.
