Need a processor and matching amp for about $1k

Have been playing with horns lately and got a pair of Klipsch KLF-20 speakers (horn tweeter and mids w/two 10 inch woofers). The whole family seems to enjoy them as we have been using them in a 2.0 HT system watching movies. (I have a totally separate system for 2 channel music) Works great if you are sitting dead center but pulls to the closest speaker otherwise. So I found a center KLF-C7 (large horn and two 8 inch mid/woofers) to match to try a 3.1 set-up. As I am a 2 channel guy I need some advice. Got $650 in the Klipsch speakers and have an Outlaw LFM-1 EX 12 inch Subwoofer. I have searched for used sets of pro/amps but they are either not paired up or the processor has no HDMI ports. I am currently using an NAD 2 channel C270 amp (120 watts) and preamp set and am pretty happy with the balance. It is set up in our living room that is about 12’ x 28’ with a vaulted ceiling, we are 10 feet away from the 55 inch LCD. Left side is closed to form an actual corner, with an opening behind us to the kitchen, and the right opens up to the front of the house/dining room behind us in a split foyer home. The Klipsch are very dynamic and have good clarity for dialog and we have no problem with having enough power. Thinking they need be mated to electronics that are a tad on the warm side of life. I am trying to keep the price down to $1000. Is the Outlaw 975 pro/5000 amp combo a good fit?
