...and (God forbid) I (and this forums mods) would not want you to debate the fact 👍
Under the STRICT conditions that nobody can debate your explanation - if you are prepared (and know the answer) perhaps you could give me some info.
I understand the need for screening where appropriate.
However, on your specific statement above, please explain what, on the reference ends, is physically making the huge difference.
You're qualified to explain. As a qualified Electronics Service Engineer, (I'd like to think) I'm qualified to understand your explanation.
If you'd prefer not answer, feel free to say, otherwise I would be most (genuinely) grateful for a once-and-for-all, definitive explanation.
Some people report hearing a difference - but they neither know nor care what's causing it.
You can't be one of those people. Something is going on, what is it?
Remember, you won't be debating , you will be merely educating.
If you do want a debate though, there's a 'mains cable' thread, where there are a few people in need of education.
