Some members assume they know how a system sounds without having heard it, and they comment on that basis. Others members do not make such assumptions. Same with gear. Some people only go on threads about gear they have heard or threads about general audio topics. Other people go on threads just to stir things up. Just different approaches, I guess. Some people like to argue, others not so much.
Good summary, Peter. I only assume good things about how other people systems sound, but like to spend a good time debating general stereo topics. IMHO your changes and experiences would be a great subject of debate if they were not reduced to the "natural/artificial" dichotomy. Particularly as they confront the Hyperbole Police
