I'm not technically knowledgable enough to be able to help, sorry. I do know that my amp designer/builder had to alter the bias substantially (up or down? don't know) to accommodate the 845Cs after my using 845Bs. This despite the fact that Sophia said no bias change would be necessary.
Regarding dynamics, my sense is that these particular 845Cs are quite a bit more dynamic than the Bs. Whether they're more dynamic than the original Cs, I'm not sure but I think so. Dave
