I really like NHT for HT, while still being good for music. I used to own the 2.9's for my fronts - very good for HT. Their VT-2.4's should be very good. Very dynamic and relatively easy to drive.
I'm not familiar with the Marantz 6300, so I don't know what it can realistically drive. Paradigms have a great reputation. Another line that you don't mention is Infinity - again, good for dual-purpose, IMO.
