Candela perhaps? I want one of those too!
Klaus's website is pretty out of date but he does have a new one in the works. This site has most information you would need though:
http://www.odysseyaudiosg.com/When I had talked to Klaus and asked him about the power output into 4 ohms IIRC he said about 260watts each for my mono's with the cap upgrade.
The Khartago will get pretty warm when you crank em up since they are in a smaller case with smaller heat sink, However the stratos doesnt usually get very warm at all even when cranking due to the excessivly large external heatsinks. Give Klaus a call, he is a great guy and wont try to sell you something that wont work in your system and that you wont be happy with. Usually the evening or nighttime Indy time is the best time to call him.
