Ben:
Given that your NHT SW10 sub is a powered one at 150 watts, receiver power should not be much of an issue. Also, the Marantz 7300 was designed for "high current" power, so it should be able to drive the NHT ST4's.
Both the NAD and Marantz generally get high marks for musicality, with the Marantz usually getting the edge in the British press.
You may wish to break out those CD's that have complex and/or unusually fast passages (Mark O'Connor's "In Full Swing" and Mahler's 2nd Symphony come to mind) and listen to both receivers again.
I have owned both brands and consider them both a cut above the Onkyo/Sony/Denon/Panasonic offerings at the same price.
Regards,
Rich
