Indeed, but this is based on the assumption that nothing has been done to purposefully manipulate L, C, and R nor does it take into account the interaction between source and load.
There’s a certain manufacturer of electronics that prefers very long speaker cables and many of their customers absolutely agree with this assessment even though it runs counter to logic. After all, cables should only be as long as needed to get from point A to point B, right? Turns out the added inductance of the very long cables is beneficial due to the design of the amplifier’s output stage.
Some cable manufacturers have adopted a similar premise and used cable construction techniques to emulate a longer cable in terms of inductance but without the added increase in resistance and capacitance.
Yes, the differences are very small, but so are the perceived sonic differences that people report upon comparison between different designs and grades of cables. No one is reporting massive changes in sonic characteristics, just very subtle nudges to different parts of the presentation.
No where here have I mentioned anything relating to cost / benefit of high-end cables. It is possible to get extremely high-performance cables at any price point and there’s a wide variation of behavior of those cables in any given system.
More money doesn’t always mean better. It can, but that’s far from universal.
