After some level of learning the eloquence of the author (barring some minimum standards) is probably not as material, it’s more about the content itself. Talking about graduate level courses, presumably ones not too math heavy, I can see this working. Or for lectures and seminars on research by professors (though one rarely is trying to remember every detail).
