Looking for a good amp and speaker combo

I currently own an old Marantz AVR that is flaky on overheating and shutting down. It was pushing Paradigm LCR speakers.
So am looking for an better solution. Want to replace the entire sound and speaker ensemble. Decided on the Denon - AVR3700H as the AV system. But want another separate amp to drive the front speakers and maybe the center as well. Any suggestions on a separate amp that may meet my needs? I plan on using my B&W 602's as front speakers to replace the paradigm, but not sure what center will work best. The Paradigm surrounds with be replaced with Ascend bookshelf's. So welcome suggestions and if I should look at other options. Thanks
