I owned KEF C40s and found very little I liked about them.
I also think the active monitor route may be right for you Doug. The Paradigm Active 20s I once owned were brilliant, as are the Quads. It's not just a matter of not having to deal with separate amplification that is a bonus, but the fact that the built in amps are tailored to the drivers. A good active monitor will usually out perform the same passive speaker with a really good outboard amp.
I forgot to mention that Al's home system with active ATC speakers is one of the best systems I've heard to date.
