Right now I have a C-2 but as noted earlier it's not very good at all.
Audyssey can't fix physical differences in speakers. Things will likely sound better with the RC-64 than with the C-2, however to get the most out of your system you are going to want to upgrade those F-30s. With a sub, you can go with bookshelves for the front and not lose anything. A pair of RB-81 II would be great up front.
