Speaker cables from Asia


I see alot of offerings on speaker cables and IC's on Ebay from Asia Etc.Has anyone tried these if so how did you make out. I also have a concern that these might be like a Rolex on the streets in N.Y. look genuine but not so.
Can anyone shed a little light

I would like to know what manufacturers (lets say Kimber, Audioquest, etc) are doing about these fraudulent products. Surely they are in the best position to stop these products (I bought fraudulent Audioquest cable - the moderator did nothing after reporting the matter?)
Regards
Thank you again for all the responses. A close fried and I where going back & forth on the subject today. We both also wondered whether cables like Audioquest and Van den Hul where manufactured in China to begin with. As Millicurie 999 stated. But even so I guess they would be considered grey market goods. Then again I go back to part of my original question has anyone tried any of these speaker cables or IC's
I once did consider getting a pair of Van den Hul Magnum hybrid speaker cable from Ebay since the price was quite cheap. After pondering for some time I ditched the idea as I didn't want to end up disappointed. Most audio stores in Ebay selling cheap stuff are from Hong Kong. As for your question how will these cables sound like compared to the original, I reckon one would take them as authentic cables unless they are compared to the original. Then again, I presume it would be difficult to differentiate original and fakes apart in double-blind test unless you cut the cables open and inspect all the details.
I think most of the 12TC stuff on ebay (sold by the meter) don't claim to be genuine Kimber Kable but rather denotes no brand or generic. What i was wondering though is the basic physics of the cable - if the manufactures in China and elsewhere use oxygen free copper and braid it the same way as Kimber then the end results, re sound quality, should be the same? Have anyone purchased these cables and tested them? if yes, please share your impressions.

The issue of stealing Kimber's patent or intellectual property is another issue and i am not sure if it applies in this case? 
I love my Kharma powercord that I bought from China for $137.   I have no doubt it is genuine.
