Amp and wiring for theta Casablanca 5.1

I would like to keep my budget in the 2K range.
I also got a great Krell KRC signature pre that I'm not sure if I can integrate into the system
My speakers are JM labs electra. What would be a good center?

1) You can use two channel but bbe sure you set up the internal menu to let it know it's all coming out of two channels. I use one 2 channel for main speakers, and a 5 channel for the rest.
Recommendations on amps depends on $, speakers, room siz, etc. etc.
2) Only jacks on the back of power amp will be input - left and right - they need to be connneected to appropriate l-r outputs on the pre.

Ricco9, more info needed, what is your budget for a amp(s) and what speakers will you be using? You will need a 5 channel amp or a 2 channel and 3 channel amp for home theater.
