Thats a big room Bill. With a lot of highly reflective surfaces too.
If it was me, I would get the Parasound A31 at 250 wpc to drive the CM9's and Center. 3K and your done. Comes in Silver or Black. Keep your Yamaha RX1020 as your processor and also use it to drive the surrounds.
Then consider some room treatments or your going to have one very bright sounding system. And the amplifier you choose won't have anything to do with it. Good luck.
