I believe in the sufficiency argument. Once you get to the level of a competently engineered cable, there is no ROI beyond that. As been said in this forum and other places, if you spend more on speaker cables and interconnects than what you can find at Blue Jeans Cable, you’ve spent too much.
I find the talk about skin effects (stranded vs. solid) to be baseless. A lifetime ago, I worked for a test and measurement company that had to measure electrical signals in the radio frequency (RF) range. We had to use exotic substrates and different metalization schemes to deal with skin effect and insertion loss but this was for signals starting in the GHz range. Audio is in the Hz and KHz range; at least a 1Mx below that threshold. These cable marketing guys borrow selectively from the electrical engineering lexicon to sound competent.
I’d take the exotic cable money and spend it on better speakers and hear a real difference.
