theaudioamp,
Your entire lengthy post of 8/8 11 PM is FALSE. In particular,
"No, any piece of equipment does not have a sound. This is Philelore and is not true."
"And I personally know lots of people who believe stuff that is absolutely not true, but that does not make them or the large amount of people who believe the same thing correct."
How do you determine the TRUTH of anything? We are talking about whether a piece of equipment, even a single wire has a sound signature. Inductive reasoning starts with observation, in this case listening under controlled conditions. Most audiophiles have repeatedly heard differences in their homes. They wouldn't spend money and keep their components if they didn't hear differences. They don't care whether measurements corroborate their sonic evaluations. Their repeated listening evaluations summate into the TRUTH that there are subjective differences when the measurement people cannot find technical answers.
However, the measurement people start from a stubborn bias that measurement tells the story. They allow their bias to obliterate any listening differences they may hear. You went into Jay's two videos with a bias to confirm your belief that there are no differences between the two Stromtanks. Later, you admitted that there are differences and you heard them, but YT flaws could not allow you to draw the obvious conclusions by everyone else who listened and found the S2500 was far superior.
Next point. You said, "A good medical doctor will listen, but they will also try to understand enough about the drug to know whether the claimed side effect is remotely possible because not all side effects will be possible." This shows how little you know about clinical practice. The typical objectivist academic doctor thinks he knows what is possible or impossible, but he bases his beliefs on published studies in academic journals. If a patient tells him something that he has not read in journals, he says there is no evidence for the patient's claim. TOTALLY WRONG. There IS evidence, albeit unpublished, but the dumb doctor is not open minded enough to listen to his patient. The doctor thinks he knows it all, but sometimes the patient knows better. Many excellent clinicians I admire write dedications in their books to patients who have taught them things, and they are grateful to their patients for that.
My conclusion is that either your listening skills are poor, OR more likely you have an agenda bias to interfere with your good hearing ability if it actually is intact. More importantly, you are not open minded enough to trust the ears of people who know there are differences. These differences are not published in academic engineering journals with double blind studies. You claim that only double blind experiments are valid. That shows you have the mindset of that dumb doctor.
