I finally made up my mind
This is what I ended up with:
Replaced my Sony fronts (small satellites) with Infinity P152's
Replaced my Sony center (small satellite) with Infinity PC250
Replaced my Sony sub with 2 Emotiva Ultra 10's
I may use the leftover Sony satellites for rear
I went to the Emotiva location after finding out it was 15 miles from my house, they demo'd the sub. I got one and liked it so much, and the price was so good, that I bought another one (with my wife's permission

) the next day. The people at Emotive were great, the demo room was full of awesome equipment.
I am very pleased with how this sounds.
