Just looked them up.. I only read about the silkworm+, not the original. From what I can tell, there is no floating shield, so you don’t have to worry about that. So, if it matters to you, just listen both directions. I don’t bother with wire directionality, I’ve yet to want to spend time listening to everything in both directions. That said, when I build my cables, I always maintained conductor direction. Enough people I trust and whose findings I have verified in my own system say it makes a difference for me to at least keep it in mind when building.
Maybe when my kids go to college and I have more time, I’ll play with directionality. Right now I’d rather use the small amount of listening time I have to actually listen to music than listen for differences. Now, if I happen to stumble across a difference during normal listening, then I’ll dig in.
