Keep your cables and try a set of Daedalus DiD’s under your Hegel and be prepared to have your mind blown. What do you feel your current cables aren’t offering you? Are your IC’s balanced or single ended? Your Golden Ears are non biwire I believe so no need to ask about jumpers. You’re just going to have to experiment but being you don’t have to deal with single or biwire cables or jumpers if I had to take a stab I’d start with IC’s and look at balance if you haven’t yet. Hopefully you have some local shops to let you drag some cables home or audiophile friends nearby... if not buy used and if you don’t like resale. Good luck.
