I agree with Rost. I've got Parasound JC-1s with my C1s. They synergize wonderfully with the Confidence line. 25 watts of Class A power into 8 ohms and 400 watts of Class AB power into 8 ohms. The amps are quite warm, though, when you run them in high bias mode, so you won't need a heater in the room with two of these amplifiers running. Dynaudio's National Marketing guy in the U.S. highly recommends the JC-1s for the Confidence line. Michael Fremer did a nice review of them in Stereophile that's available on the internet. I would have to say his review is very accurate.
