From what I have read, JohnK only passes on scientifically validated information. You can say two receivers sound different until you're blue in the face -- and you might even be correct -- but the brick wall we keep running up against is that some of us don't believe our ears can be trusted objectively. For some of us, hearing isn't believing. For those of us in this camp, we like to see controlled tests performed to either validate or refute those differences.
People who do not rely on such tests are not inferior to those who do. (I realize this might have been implied in the past, and I apologize if I was one of them.) In fact, you probably have an easier time buying audio equipment because you don't have the added burden of questioning the validity of what your ears are hearing. For that I am envious.
