What is best center speaker?

I have an HT set up with bryston 4b amps (4 ) an AV 9000 marantz a 65in HDTV and Piega P10 as fronts Piega P5 as back and the Piega Center. I have now blown the center twice and am tired of sending it back east to be fixed. I need a center that will fit in with the Piega and will take 200 to 400 watts and sound outstanding. Does a center like this exist? (The Piega center is a wimp)Thanks for your input.
