I never said V-peak and V-RMS are the same for a sine wave. But you are right that I was incorrect about the dBFS measurement being the same. (I seem to recall an instance where a sine wave measured the same, but a complex waveform didn't.) I apologize for disseminating incorrect information.
Either way, the proper way to calibrate converters is to set the digital value in the DAW to a peak dBFS level (e.g. -20 or -18), then measure the V-RMS with a TrueRMS voltmeter.
