I Just Don't Hear It - I wish I did

I am frustrated because I am an audiophile who cannot discern details from so many of the methods praised by other audiophiles. I joke about not having golden ears. That said, I can easily discern and appreciate good soundstage, image, balance, tone, timbre, transparency and even the synergy of a system. I am however unable to hear the improvements that result from, say a piece of Teflon tape or a $5.00 item from the plumbing aisle at Home Depot. Furthermore, I think it is grossly unfair that I must pay in multiples of one hundred, or even one thousand just to gain relatively slight improvements in transparency, detail, timbre soundstage, etc., when other audiophiles can gain the same level of details from a ten dollar tweak. In an effort to sooth my frustration, I tell myself that my fellow audiophiles are experiencing a placebo effect of some sort. Does anyone else struggle to hear….no wait; does anyone else struggle to comprehend how someone else can hear the perceived benefits gained by the inclusion of any number of highly touted tweaks/gimmicks (brass screws, copper couplers, Teflon tape, maple hardwood, racquet balls, etc.) I mean, the claims are that these methods actually result in improved soundstage, image, detail (“blacker backgrounds”), clarity, bass definition, etc.
Am I alone in my frustration here?
