ATI 2005 or Emotiva EPA-5

I need an amp to power my center and surrounds. I have a Classse CA2200 for stereo and want to fill in the rest. I like made in in North America but not if I'm wasting money. The numbers for the ATI are great, the Emotiva's are good and the price is better. I would like an amp with enough power to enable me to have flexibility down the road for any speakers I use. What do you think? $2000 or less, used is ok.
Thanks.
