Looks like the speakers connect to regular speaker posts and the sub is a powered sub, so yes, you can use the speakers/sub with any of the newer models you are considering. 75W should be more than sufficient to power the speakers. Choose the model that best meets your budget and feature requirements. Although note that upgrading to the next higher Denon model, 1613 will provide both networking and Audyssey MultEQ (auto EQ for the speakers). Pick up the phone and "call" AVS sales or Electronics Expo for their best price on the 1613.
