Multi-Channle Amp Dilemma

I am trying to decide between the following amplifiers for my HT set-up: Theta Dreadnaught II, Pass X150 (front r&l) and an X3 for rears and center, Bat 6200 and a Classe CAV-180. I use a Krell 7.1 for my processor and have B&W N803's for the fronts, the HTM2 center and N805s for the rears. I recently sold my Bryston 9B because I did not think it brought out the best in my speakers. I would like to make the best choice, so that I can sit back and enjoy the music and movies. By the way, I use the system 70% for HT and 30% for 2 channel.

As always, your thoughts are very much appreciated.
