Amp for use with Jm Labs Electra 946's

Any amp suggestions for use with the 946's? I'm currently looking solid state and would appreciate suggestions for both power amps and integrated. I've been considering the Krell 400ix, Krell Mono's as well as some of the Mac's. Room is fairly large, living room dining room combo, coverted to pool room and listening area. 23 ft. ceilings and fairly open.

I'd appreciate any adivce.

Thanks.
