I agree with Lak that you should call Coda.
It could be several things, perhaps the preamp section of the csib is passive, and you were using an active Musical Fidelity preamp. Or it could be a difference in input voltages required for full output of the amp, or it could be defective.
I would not expect the volume to "break in" though. Call Coda, you may get to talk with Doug Dale, one of the founding engineers. They are great people to work with.
