I am currently using an Emotiva XPA5 - 200 x 5. I may upgrade. I would keep the current amp for the center and rears and get a 2 x 250 - 2 channel or mono blocks for the mains. I would probably again get the Emotiva unless I saw a good deal on used.
I use this for mostly music, either 2 channel or 5.1 with sacd's or audio DVD'S with an occasional movie.
