Amps for Klipschorn speakers

I have been looking at the Atma-spheres particularly the M60 mono blocks and the MP-3 pre amp. They seem to get rave reviews but I am a little worried about the heat they might put off and just having an amp with that many tubes so I am still on the fence with that one.

Another option I am considering is an ARC VS115 with a REF-3 pre amp.

I read some threads on the Cary SLI-80 several of you suggested and that also seems like a unit I might would want. I just moved to a new house and really need to upgrade my living room as well as a master bedroom so the Cary looks like it may be a good fit there.

How can I run a center speaker with my Khorns? I have a pair of Cornwalls I could use. Would I have to buy an amp with a center out and if so do many have them?

I am still looking up all of the amps suggested. I do appreciate the help.

Good information, guys. So far, all of the SS amps I have tried on the Khorns have been too bright. I brought over a friends Marantz 8b today but it only worked on one channel and one tube started glowing so I turned it off so I didn't really get to hear it. I am going to have a look at the small amps as you guys have suggested.

Mark, I don't know enough to know what I am looking at. Can you tell me why I should consider this amp? Thanks...
