My pick would be the Aerial 7b's of the 2 you've mentioned. Excellent build quality. It's a good speaker although I'm a first order guy and use Vandersteen's. As mentioned above, the amp is a good match with the Steens.
The 7b's are my favorite non time aligned - phase coherent speaker in their price range.
