OP made his point in a questionable way, but it's a fair point nonetheless.
The problem with most armchair Audiophiles perorating endlessly in forums about the stunning aural benefits of tweaks, network gear and cryogenically treated USB cables is that they can't tell the difference between a soldering station and a train station and they've never even taken the covers off their gear. As a result, they have no idea what lurks inside. How about $4000 power cords going into $500 wall receptacles, themselves screwed onto decidedly non-Audiophile Romex held together by garbage wire nuts? Wire nuts! Talk about microphonics now. And how about $400 graphene fuses snapped into 10-cent fuse holders made of common steel? Etc
Meanwhile, everyone politely agrees to ooh and aah over the emperor's new clothes, including genuine audiophiles who know better.
