Yes the C200 will convert an unbalanced input signal to a blanced one. I beleave it splits the signal so that half the wave form goes to one set of circuits and the other half goes to the other.
If at some point in the chain it is unbalanced then the signal is murged into a single wave form.
If you want a fully balanced system you would want the pre-amp and amp and even the source to have the same circuit design to fully utilize it.
I hear a big difference using a balanced signal directly from my fully balanced McIntoh MDA1000 to my fully balanced Cary CAD-211's
When I use the unbalanced cables between the two it is does not dance and sing the same way as it does with the balanced cables.
