So the way to signal that one is an evidence based aficionado of sound is to call yourself a "sound nerd?" In today's parlance, "audiophiles" are all deluded woo-woo proponents who are deserving of ridicule. (I find that to be a form of shallow prejudice: One can simply evaluate the science behind what someone is saying.)
That people's reaction to essentially the same comment would vary vastly with the form of self-identification. I suspect people are downvoting my comment just because it contains the word "audiophile." The point is that the topic is subject to a lot of unthinking prejudice in forums like this.
