Which Amp for my NHT 1.5's

I am running 5 Parasound 1200A monoblocks with my ht system which includes the 2500u Parasound processor and NHT 1.5 speakers. What would be a good amp to drive my front mains. I was thinking of the Parasound HCA 1000a or HCA 1500a and using the monoblocks to drive the zone.
