Lower capacitance will always help, making the whole system easier to drive. That said, the older cloth cables were mated to drivers with far lower capacitance so they would be about par with the modern stuff. Still it wouldn't hurt to use a lower capacitance cable.
Going the whole HE-1 route though is just idiotic. Cramming class A/B drivers (at best) into the capsules and instead carry a pile of signal into the phones is a pretty crappy compromise. Reeks of the usual Sennheiser "we did something cool but utterly stupid (HE90 glass stators)" which they are kinda known for...
