LSi9/7 System reciever

Need some help here on purchasing a new receiver for my LSi9,LSi7, LSi Center system. I am upgrading my old Pioneer receiver that has a blown amp. Right now I am looking at Denon 4500H, Marantz 6013, and Pioneer SC701. Having asked around about power requirements to drive these 4 ohm monsters I am being pushed toward another Pioneer like the SC701 due to the power and efficiency of the Class D3 amps. On my old SC1523 I was not impressed with MACC calibration and much preferred my Audessey Cal on my Onkyo in the Den. My Heart is thinking the Marantz which has AB amps, but do I need the power of the Pioneer D3 amps to get the most from these speakers.
Any thoughts are greatly appreciated,
