"Also, and for the life of me, I do not know why… but the character of an interconnect tends to be the same as the character of a power cord. Why they would sound similar is completely beyond me. This is just a casual observation by me. Perhaps others have different experiences."
You are not hallucinating. I’ve made similar observations. When "better stuff" is inserted into the musical and/or power path, my experience is that in many cases the sonic benefits are strikingly similar to other items that have a completely different "job description".
