as i think more about the concept of prejudice, i think that some audiophiles are prejudiced against components and /or stereo systems they don't like. they are closed minded when people express preferences which are at odds with their pre-conceived notions of good sound.
i have encountered many cases of this personally, because i tend to prefer stereo systems which are subtractively colored, while most prefer resolution and accuracy, and a lack of coloration.
since audio is a subjective hobby, there is no absolute better or worse sound, only different sets of idiosyncratically based criteria.
