why does it have to be several kilohms to be significant? in the measurements i've seen, some cables had over 20 ohms resistance at 20kHz. besides, we're not just talking about speaker cables but also other cables like interconnects where a difference would be more audibly significant.MarkZ said:Resistance does not significantly rise with frequency. The way I define "significantly", it would have to come somewhere close to the several kilohm input impedance of the amplifier. But it doesn't. It'll add only a couple ohms. No one would call that significant.
Besides, like I said elsewhere, the easiest and cheapest way to combat the skin effect is by increasing wire gauge (thereby increasing surface area), not by implementing special new strand/dielectric properties or cable geometries.
