Mr. ganainm
I’d read the long article. It is not providing an answer, of what speakers cables I need to my system. It mostly tackles phenomena that are minor or do not exist at all with speaker cables.
I can NOT take that information that your article provides, and go shopping for my new speaker cables.
The article may look impressing to a none engineering skilled eye. For an engineer (mostly analog) It will be on the edge of ridicules or absurd.
What I’m saying, is that I can do such a calculation and provide the accurate data of what cable I need. As that been repeated and the results were profound and consistence, I can tell that it works.
