@Tubewin I was relieved to read this. I thought I was alone in liking the stock cable (apart from the sleeving ). I like that in many ways (not all) it seems to present the music as mastered. I find myself returning to as the default cable.
I have two 3rd party cable replacements (midrange) both of which made changes to the sound of my Susvaras. One set sounded nice but I realised pretty quickly that every track sounded ok and it seemed to fill in mastering deficiencies (well defined bass, reasonable coherence) - all the tracks just sounded nice. That might suit some bit isn't what I'm after.
I'm after a cable that will give me the music, mastering and timbre - warts and all - with musicality!
I'm considering either the Nirvana and Voila as potential upgrades.
