Best dd 5.1/dts processor for around 2k used

Hello all
looking to upgrade my proceed avp-s
wondering if anyone has any thoughts on the best combo pre-surround processor that does dd5.1, dts and limited video switching in a system that does 50/50 duty as a home theater and 2 channel set-up??
I have revel performa speakers all around, a rel sub woofer. proceed amps and an ecp 8000 projector fed by a faroudja vp201
my source is a cal audio cl2500 combo cd/dvd player
thanks
