I have pretty much the exact same speakers as you in a 5.1 setup, and have been using a McCormack DNA 5-channel amp with satisfaction. I was also considering some of the same processors as an upgrade from my old Rotel RSP-1066, but looking to spend no more than $7,000. My narrowed down choices were the Classe SSP800, Arcam AV888, Integra DHC 80.1, Anthem AVM50v, and Marantz AV8003, but I decided to order the Arcam AV888. I'll let you know my thoughts once I get it calibrated and fired-up in my theater room.
