Katee, you inherited quite a setup! The NAD is a fine amp. Driving speakers is not whether or not they will or will not, but more about the room and how loud you like it. The question really: I have a small/medium/large room and like to listen to rock/jazz/rap/classical/folk and I like it at soft/medium/loud volumes. I have not heard many NAD amps, but the reviews are good. 88 dB sensitivity which is not high. They are known for being detailed. The NAD should be fine in an average room with good volume. As Riley stated, now you decide if you like the way it makes music. A great start! Have fun!
