Help me decide: Best 5 channel AMP for me

I have about $2000 to spend.

I'm about 70% music(2ch & 5ch)/30% movies

Speakers: 4x EPOS ELS3 monitors, 1x EPOS ELSC Centre, 1x Velodyne CHT10 sub
Componets: I've got a Marantz DV8400, ICBM Bass Manager, Audio Refinement PRE-5

What would you recommend. I'm probably going to go for an AMP5 or a Bryston 5x120. I am not interested in Outlaw, or Sherbourn.

Anyother suggestions before I pull the trigger?

Thanks,

Jason
