Which amp for the audio physic caldera

i am glad to own the audio physic caldera (three box version). i use the tweeter of the audio physic cerubin instead of the original one which is much better. i although have two audio physic rhea and a wadia 861 se which i use as cdp and preamp. so i am just looking for a good poweramp. i would like to have two mono amps and at the moment i´d go for the kronzilla dm. is there anyone who has experiance with this setup and has another idea, please tell me.
