Part of my OP is about "biases." Your biases my biases. You develop biases over time. It's based on human survival.. the known pathway to safety for the caveman.
As an expert reviewer (why does this upset so many people, the word expert- I'm sure every riled up poster here is an expert in something, it's just not in audio), I have learned over time what my audio biases are due to the audition of a wide variety of audio equipment in many settings, homes, shows and stores. Most people do not have this experience. It is very evident when I visit someone's home and their system is threadbare, two dimensional, and bright in the upper frequencies, despite the fact they attend a show or two every other year and frequently visit other audiophile homes. I suspect they have built in a bias for detail appreciation or perhaps they may suffer from a mild form of tinnitus. Wherever the reason, they have a bias for their own system and sound and when asked they say others systems "suck". What I see happening here in this thread is denial, just like the fellow with the bright system, he simply does not believe (he denies) his system is bright and two dimensional. When he goes to a show he hates the sound of most systems and when he speaks of other audiophile's rooms he has disparaging comments.
This is a bias issue. His bias. If this person posts on the Internet that a room at the show sucked and was only in it for 15 seconds... I believe him. I believe in his belief, but not that the room sucked.
Everybody riled up here is mad, they are mad because they have personal denial of being wrong. So when they are challenged, they fight. I posted this thread because this has been accepted Internet behavior for years. To state an opinion without the appropriate knowledge and with perhaps tremendous built in bias. That is my opinion. The problem is, this behavior has gone unchallenged for years. This is the first time they have been "called out" and they don't like it.
This is not about audio. This thread is about the human nature. This thread is about being challenged when they themselves have challenged others for years with impunity. Exhibitors can't challenge them in public. Someone should step up. Now someone did and they don't like it.
