Keep the 5803 and buy a nice 2 channel amp for the right and left or a killer 5 channel. If you go with 2 channel amp for now, it will free up some power in the 5803 for the other channels. Just get a 2 channel that you can mate with another 3,4 or 5 channel in the future?
Personally, I'd say go with a really nice 5 channel with those speakers. They deserve it! Sunfire, Sherbourn, Anthem and on and on...
