Well, a cable's geometry ultimately establishes the cable's resistance, inductance and capacitance, which is measurable. So what exactly is the revelation here?
But they haven't. So I still don't see anything particularly useful.
I truly think that cable science is only at the beginning and has yet to produce valuable data showing their effect on audio.
I disagree. There's perhaps nothing more well understood than a cable.
No. But we're hardly in the "flat earth" stage when it comes to cables. Well, at least the rest of the world is. Much of high end audio is still something of a technological backwater where ignorance, myth and superstition still hold sway.
