I had the reverse situation. I bought c-j premier 12's, and the sound was so laid back, dark, and rich, that I was hesitant to match it with a c-j preamp. Mind you, this was just *my* situation, with *my* speakers, and might not apply to everyone else.
Anyway, I went with an ARC Ref 1, which has a leaner, brighter sound. This balanced the lushness of the c-j beautifully, and in fact allowed it to come through with great impact.
Therefore, if I were in your position, I might consider an ARC power amp, or even solid state--in short, something with a lighter, brighter tonal balance. For me, a c-j preamp mated with a c-j power amp--in *my* situation--would probably have been too much of a good thing.
As a matter of fact, my prior situation was perhaps even more similar to yours: I had a c-j PV-5 preamp mated with a solid state PS Audio 200c, and this worked beautifully for around 20 years.
