I don’t remember the specifics, but I tried asking for some audio advice from a Genius once. I realized fairly quickly that I actually knew more about audio than he did, and that I should do my own research. edit: That said, I ended up asking the question to one of my professors, who also works periodically as an Apple Genius. But the reason the professor could answer the question was that he’s a studio engineering professor. Well… maybe he’s a professor because he knows such things. Anyway, being an Apple Genius didn’t have anything to do with him being able to answer the question.
