Audioquest SKY Interconnects

I see on eBay what I believe are copies of the AQ Sky interconnects for around $150-$200 used USD being sold out of China.  Does anyone have any experience with these cables?  Are they worth a try or would I be wasting my time?  The reason I am asking is that I would be probably using them in Vandersteen MP filters that I build for my Vanderteen speakers which allows me to use higher grade parts in the filters copies.  Previously I used AQ Diamonback ICs with great success but I sold those when I sold my Vandersteen model 5s.

Thanks for your input/advice.
