What do you use it with? S8f? Also **** has different types of the cables. Some are good match to your iem, some not.The **** cables are bad ... I have one too ... the connection is loose and the sound became muddy ... you get what you pay for ...
If your iem tuned to work with certain type of cable, it needs that type of cable to sound its best. You can tweak it somewhat to your preference using similarly structured cables with slight differences. (Of course given that IEM tuned well)
Yes, QC may not be the best with chi-fi but materials are the same. Type of braid matters, People complained on ibasso it01 cable braided too loosely but IT"S DONE INTENTIONALLY. Braid tightness changing the sound, length, thickness of the insulation etc...
More expensive cable IS NOT better if it's not a good match!
What sounds best is subjective and the only thing that matters.
In a few days I will test it again with stock cable and will see what I'll prefer
