Theoretically, yes. Practically, no in my experience. Over the years, I've frequently witnessed wide variations between theory and practice. Even controlled experiments can NOT necessarily determine the overall experience of a human, in this case by a listener. I wish VoN would switch to Mode B while retaining 16 QAM modulation. Mode B works well for intercontinental digital broadcasts while allowing more capacity than Mode C.
