Dan - I would much prefer the 1.3 mk2's taken as an issue by itself. That said, I think you'll find the 52's a better match for the Rotel. That's a nice receiver, but the discontinued Contour's (such as the 1.3's) REALLY soak up the current. Unless you're planning on upgrading the receiver in the fairly near future, I think you'll like the 52's better.
I do like the sound of the 1.3's better than the 52's and, no, I don't think there is a tonal balance problem. -Kirk
