Missing from that video is a listening test. Those home-made cables might sound good. But his opening assertion: "The best cable or wire for audio might be hiding right underneath your nose..."
I think he gives us his opinion in the title of the video. He also presents a lot more in the form of a logical argument, telling us how this wire is able to take a very weak video signal and shield it from outside interference over very long distances. A listening test would simply be more of this one man’s opinion. Just as the bulk of your message is one man’s opinion.
My opinion is that I have listened to some extremely good and expensive 100k type systems and thoroughly enjoyed the music. Then I have returned home and listened to a much more modest system and thoroughly enjoyed the music. I have also purchased moderately expensive cables, such as mid-level audio quest and DH labs stuff and compared it with no name, lamp cord and Amazon‘s best types of cables and noticed differences so small that they made me doubt my judgment as to whether they were doing anything at all. In the end, I have opted for solid pro level type brands, such as cannare and Belken And feel they do not get in the way of my enjoyment of the music. I am always open to being convinced that I was in error if someone can present a strong, rational argument, and or some associated data. But when it comes down to opinions, one person‘s opinion is simply just that.
