for cables, i've used Supras for years with Dyns and they are cheap and great as they are very neutral. you don't need to spend more---and i would never put a networked cable on a Dynaudio. they are used to tame bright speakers. and Dynaudio is definitely not bright. i wouldn't use Cardas either which is usually a smooth sound cable (i tried Golden Reference on my old Wilson system and didn't really care for it).
but none of what you want has to do with cables, so i would work with speaker placement and room first. in fact, selling all of your Nordost gear and using it for room treatments will put you in the right direction.
btw, i listen to a lot of house music on mine and dj some :) the C1s have tremendous bass, and i've thought about upgrading to C4s, but they are quite big beasts.
