@prof You are such an expert in your opinion denying the plausibility that I hear great differences and can make an informed opinion of my own.
No, precisely the opposite. I recognize my limitations as NOT being an expert.
That’s why I value explanations by actual experts.
My whole approach starts from my (and humans in general) fallibility.
This seems hard to grasp for people who have trouble accepting their own experiences may be fallible.
When I say there is a very significant difference, THERE IS!!!!!
That is the confidence one sees from religious dogmatists. "I experienced it; nobody can tell me otherwise." By valuing your subjective opinion above any other evidence, you have made your belief unfalsifiable - no outside evidence to the contrary can budge you. I personally, along with plenty of others, prefer not to treat audio as if it were like religion.
So to provide a contrast: I really seem to perceive "obvious" differences when I’ve done some tube rolling. I’m fine to proceed on my experience. But I recognize I’m quite fallible and like anyone prone to listening biases. Therefore I would not simply declare "If I say there is an obvious difference THERE IS." I can acknowledge the point made by a skeptic that it could be some type of expectation effect or perceptual bias, rather than the sound changing audibly. I’m willing to be wrong, and it does not threaten my self-worth to admit my perception may be in error.
So, I guess that’s how we see things differently.
Blind ABX testing on these tweaks and I bet I couldn’t identify the differences. Change from six Pangea power cables to six Grover Huffman power cables in a high end/high cost system-OBVIOUSLY SUPERIOR!!!!!
So...do you mean you have reliably identified these power cables under blind test conditions?
