The OP's source a 28 year old test that only tested differences between wire gauges. The only test that matters is the person doing the listening, in their own system with their own music. Theories and opinions by others are irrelevant.

Good article! Long, but it makes sense. I have used these RadioShack interconnects that he is talking about some decades ago and can attest that they were first rates (although they did subscribe to the notion that the signal was directional). Bottom lines, one should be honest with oneself: at the end of the day, it might be cheaper.

It’s not that complicated. Don’t buy complete junk that’s going to be a weak link, and don’t spend more than about 5% of your system cost on cables because you can probably get more improvements elsewhere. Then forget about it and enjoy.

And again and again, and round and round.

The author of the article didn’t say that cables don’t matter. His company actually sells cables. What he’s saying is that a lot of expensive ones don’t justify the price tag and a correctly designed one should not be overpriced because it’s not hard to design a good cable because we are dealing with known theories. Read the article, it makes sense.
