I had the pleasure of listening to the KS 1030 vs the KS 1036 with Dick Diamond (formerly with Kimber) in my home with my new YG Anat IIs. These are the single ended versions of the models you reference but perhaps my experience will have relevance.
I think the extra conductors of the "36" models may ameliorate impedance mismatches between preamp and amp as Kusina suggests, but could impair the delicacy and nuance of signal transmission between line level sources and the preamp.
I have found the lower stranded "30" to have more liveliness, dynamics, soundstage, quickness, air and PRAT with front end sources to the preamp than the "36".
Sometimes less is more.
More or less.
