There are few amps that can deal with the Kappa 9's vicious load. I believe it dips to under 2 ohms. I'm actually impressed the Adcom keeps running as that says alot for the Adcom. Two amps I know that will drive that speaker well, my choice would be an Innersound ESL, it's going to drive anything and sound relaxed doing so, it will drive 1/2 ohm!
Another amp is the Parasound HCA 3500. Do a search here on Audiogon as this has been brought up before. It seems like one guy was having most amps he tried shut down. That speaker is one of the most difficult loads I'm aware of.
