WaveLab Monitor recording

What we hear after switching on Monitoring during recording, is that 100% true to the source in terms of fidelity?

No. It never is, with any program. If you’re worried about running your signal through a digital monitoring stage, don’t use one.

100% is never possible

You mean when you activate the monitoring (that is set to a different physical output) that goes to the outboard and coming back into the ADC into a stereo track ?

Yes, pepe441. I understand that there may be some change because of cabling, power supplies etc…but what I needed a confirmation on was that WaveLab does not do any curtailment to save resources.
