Best Preamp processor

I need a new pre-amp processor and want to know what would best fit my system. I want to listen to music and home theater.

I have a BAT multichannel amp, Wilson speakers, Audio Control Diva (I have a terrible room) and Runco projector. I have the Lumagen Radience XE+ video processor but have had problems with it working properly with the projector.

Thanks for your thoughts.
