Help: processor upgrade from Aragon Soundstage

I am ready to make the leap to 1080p, blue-ray and HDMI. My current setup is an Aragon Soundstage powered by a Pass Labs x350 and Aragon 8008x3. My upgrade will require changing the processor, projector and purchasing a blue ray play. I am looking for processor that will do good job managing the video switching but it must also do an excellent job on 2 channel audio. I will also be purchasing a mid level projector and a PS3 for blue-ray.

Any help with identifying a handful of processors to evaluate would be greatly appreciated.

Thanks.
