Why do Audiophiles feel the need...

Why do so many audiophiles feel the need to post opinions on gear they've never owned or had such limited experience with that their opinion is valueless to the OP? Not only here, but on other audio forums, at least 50% of the posts (and I think I'm being generous) start with: I've never heard the XYZ but...

When I was participating in an auto detailing forum, teaching myself the finer points of achieving an exquisite auto finish, if someone would ask about brand X polish, I would never see a post stating: "I've never used it, but..."

My opinion is that many people spend so much time dreaming about this stuff that they've convinced themselves they know what it actually sounds like. I know it's only a hobby, but I think a poster who asks about a specific piece of gear is better served by opinions of those with experience with that gear. Maybe it's just me. Sorry if I offended anyone.
