Wow, so much anti-science hostility. It’s one thing to argue about the efficacy of cables, but let’s not get off the rails! Science created audio reproduction. Science improves it. Science probably saved your life once. Science has a say in this matter.
I didn’t see anything in ahuvia’s post that was rude or should have drawn such hostility. If the mere idea of skepticism is so threatening, the "cables matter" side needs to do the work to feel more emotionally secure. Come up with some tests and prove it.
I do agree that you can only go so far referencing published studies and that personal experience does matter. I also agree that it doesn’t really matter what other people think about a tweak you make that you like in your system.
However, that goes both ways. You say you don’t care what people think but you only really don’t care what people think if they disagree with you. I would say that’s not the optimal attitude to learn things or to convince others. Clearly when someone posts about a positive cable improvement they do care what people think when people agree with the post.
Forums are not echo chambers. People need to learn to deal with dissent. There is a Truth here, and maybe finding that starts with showing some mutual respect?
(I’m skeptical that power cables matter outside of quality construction and gauge but as I have never done a test and wouldn’t have the budget anyway I am more interested in reading data, facts and experiences and find the flaming counterproductive.)
EDIT: to the OP, the above doesn't refer to you as I think your posts are pretty balanced and respectful. But a few of the above set me off.
