I guess I can talk some more about my experience with cables, although my thoughts on them are decidedly about their physical characteristics.
If you're going to buy a Hakugei cable, I'd avoid their cables that use paracord for the wrap. The one that comes with the SeeAudio Bravery is awfully microphonic; in general, paracord is not the best choice of material even though I like it visually. It has a tendency to split, kink, and generate a lot of feedback. I'm also not a fan of many of the popular, high-end IEM cables - at least not from a usability standpoint. I found the thicker EA and Eletech cables difficult to use, and they also feel rather cheap in my opinion. The PWA cables are some of the worst offenders, though. Machining lines, jagged cuts to the wraps, poor attention to detail, etc. I believe most of these brands' cables also use protruding 2-pin connectors which are more likely to put strain on the flush 64A connectors.
Generally, I'm not a fan of thicker cables. They're unwieldy, put more strain on your ears, and usually difficult to fit into cases. The cables that I like the most tend to be thinner, more pliable, and with flush connectors. The DUNU cables lack flush connectors, but I'm partial to the DUW02/S and the Blanche (probably one of the highest quality cables I've held). I also like
this one from Moondrop, although the swappable termination is a weak point (I know because I snapped mine). Some other cables that seem good are the
Xinhs cables off of Aliexpress, where you have a lot of options for the termination. I might pick a couple of those up at some point.
