Colin is right in that there should be some kind of experience involved in a persons background. I agree with that but the closest I can see is acoustical or electrical engineer, musical degree etc. It's almost like the people you use to judge the music are as subjective as the music and the system itself? I didn't think I ever questioned Brodski's point. More and more we people who have things because they 'want' them. Not because they use the expensive motorcycle or need the expensive clubs. They just want them and enjoy having them. People have hobbies and collect things. Some people collect old things, antiques and classics. some folks collect new things. Some times you use them and other times just look or know its there.
Does that mean your an expert in what ever prize you have? doubtful, right. Maybes there's a few that parade around as an expert or try to sell a service under such pretense. By and large there's a lot chatter and free advise. We know what free advice is worth!
