I have had Raven C's for the last three years and they are amazing. On the used market, I don't think they have an equal. They need lots of power to sound their best (I have JC1's) so you have a very good set-up indeed.
These speakers are very placement sensitive so take your time during the set-up. They sound best if you give them some space.
Too bad my system is down for the count at the moment... sigh
