Thanks for the info regarding the JC-1. I was considering one of the new Passamps, the 250.5 model. They will have the balls to drive these speakers, I think, and judging from the opinions I have seen, they are fine mamps. I'd like to hear more possibilities before I make a change, but I think the Gamut amp is just not "strong " enough for a low-medium sensitivity speaker, especially at louder volumes which I like.
