Different guitar cables are due to pretty large differences in capacitance - in other words, it's no longer a valid cable.
It's an "audiophile" trick as old as they come, you add a resistor and/or capacitor in the "cable".
I wouldn't put such an "eq" beyond VSonic, but perhaps this is actually a driver change...
Well resistors, there is the the ER-4P versus ER-4S, and Vsonic R04 updated version versus Vsonic R04 flagship version.
I think Vsonic would say if it's resistance. It's more likely to be a change in the voice coil, magnetic flux density, bio-cellulose lab process, or *gasp* more strands, thicker, or purer silver content in the cable!
If you compare the Sony EX1000 cables there was 1 ohm difference is resistance, when measuring 4N versus 7N, I don't think the point of higher purity is only ~1 ohm less resistance in a cable lol.
I can't recall which forum it was, a Korean one I think, they said the Japanese version of the EX1000 sounded better (/different) due to the thicker cable with higher purity copper.
I don't necessarily believe that but yeah, hey, it's just a quest for purity.
