Sea2,
I've had the JC-1's and several Mac amps in my system. I could live with any of them. It's going to be which one draws you in more. Make the time to listen to both. People use analogies to cars and wine when comparing Amps. The one I use is: I've dated Pamela Anderson and Jessica Simpson. I prefered one, you might prefer the other. Nobody can tell you which one you will like best. If you get that, it will clear up alot of your confusion. I also see an amp and speaker sort of shaking hands together. Some amps and speakers like each other some don't. Doesn't mean one is bad. One thing about the Mac with it's autoformers, if you like its sound, you're probably covered with future speaker changes. Goof luck.
