The only way to ascertain expertise on Agon is to judge a user’s posting history.Mostly true but another way to help understand a poster's perspective is to take a look at their virtual system. For example, I use inefficient speakers and big power amps so I am certainly not the person to listen to regarding high efficiency speakers and single-ended triode amplifiers, other than I have said I wish I had started out with more efficient speakers. It is both interesting and informative to look at the virtual systems here, and fun too. While I have no problem with people who do not post their virtual systems, when they do that information sometimes helps me understand where they are coming from.
