Sorry for the late reply; what did you end up doing? I'm probably too late for my comments, but here they are.
I've only heard Emotiva's in fellow enthusiasts' homes and can't really comment; the system context were totally different. One of my friends does have Dunlavy speakers as well, and I thought the Emotiva's a bit to bright for me (I have Dunlavy's as well).
I've always liked the Rotel sound. I had a Rotel RMB-985 as a "loaner" in between upgrading to tubes and it was fantasic (maybe I was biased at the price: it was a free loaner!
). Smooth, detailed on the top end.
However, I've never taken them head-to-head, so take what I say a little with a grain of salt.
