The audio snobbery is aimed more towards various listeners than anyone else. Folks who like warm equipment understandably discount cables and DACs, while those who seek every detail frequently belittle those liking a warmer system that hides details.
As for reviewers, I think there are some misconceptions.
"Most reviewers don’t have the ability to correctly capture the sound signature of a component, especially the old guys with hearing degradation."
A reviewer's hearing acuity is only one factor. Age-related hearing loss is common, particularly at higher frequencies, but it varies greatly from person to person. Experience gained over decades of critical listening can compensate for some limitations, while younger reviewers may have better hearing but less-developed listening skills. Neither age nor experience alone determines how useful a review will be.
The truth is that some older adults retain remarkably good hearing, and hearing tests don't fully predict critical listening ability. The ability to analyze and describe sound is a learned skill that often improves with experience.
So I would avoid implying that "old guys" are generally less reliable. A better criticism is that few reviewers—regardless of age—consistently provide sufficiently detailed, repeatable descriptions of a component's sonic character for readers with different priorities.
I have had to have frequent hearing tests for decades, and frankly, spatial cues are frequently found from high frequency harmonics and overtones. The Audiophiliac has since his youth loved Vandersteen speakers. To me earlier Vandersteens at least sound to me like speakers covered in moving blankets. He's not wrong, we just admire different qualities.
Nor do I care to exploit, for purposes of s self promotion, youthful reviewers general inexperience. Shall we look at conductors?
Unlike instrumentalists or singers, conductors are widely regarded as reaching their artistic peak later in life. There is no fixed age, but among musicians, critics, and orchestras, the broad consensus is:
30s–40s: Technical mastery and career building.
50s–70s: Often considered the artistic prime for many great conductors.
60s: Frequently viewed as the "sweet spot," combining decades of experience with sufficient physical stamina. One survey of the world's busiest conductors found an average age of about 62.
70s–80s: Many elite conductors remain at or near their peak, particularly in repertoire requiring deep interpretive insight rather than sheer physical intensity.
So, even if some or many(?) experience some hearing loss, it doesn't appear to stop their improving in their profession.
I once had a fellow talk about his generation not having held power as president and how my generation had done badly. I had to make him aware that a generation did not separate us, and that at that time my generation had not been elected to the presidency. I thought his ignorance was interesting. Morals, ethics, and fundamental beliefs, and sound temperment more than age generally determine good leadership. Having been in the military for some time I was surprised that he wasn't aware of that. Oh well, prejudices unexamined bite us all in the rear from time to time.
