Amp suggestions to mate with EAR 864 pre

Welcome any suggestions/experience with a power amp to match with an EAR 864. I'm leaning toward a SS amp...Pass, Rowland, etc. but would also consider a tube amp (currently have a BAT VK75) that is dependable and user friendly. Listen to alot of female vocals, rock, some classical.

Associated equipment: BAT VK5DSE CD player and Wilson Benesch ARC speakers. Planning to add phono with new system.

Thanks!
