I've never once been disappointed with anything Xangsane. There is this other ongoing thread on chinese counterfeit cables - it's redundant, most if not all counterfeit cables are poor, irrespective of counterfeit or not, which I don't really care either way.
Xang on the other hand, go full chinese, it's excellent product, all of it. 9001 is great cable, I find the conductor a bit thin, I'd really recommend the 9003ag, that is fine cable. Their silver solid core is just excellent too. I've found their premade stuff a bit pricey, but their silver ethernet cable is also excellent - I usually do not hesitate in the least on Xangsane, I know I'll be sent great sounding quality whatever it is..
