Outstanding 5.1 pre/pro with comp. video switch'g

Looking for an outstanding 5.1 pre/pro with excellent component video switching. Doesn't necessarily have to be a great 2 channel preamp as I am purchasing a nice 2 channel tubed preamp. I currently have an arcam av8 pre/pro which is 7.1 ch. with all the bells and whistles but I don't use them. All thoughts and comments are greatly appreciated. My speakers are the piega c8ltd ribbon hybrid speakers, which are stereophile class a rated. Thanks.
