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.

Long time ago AQ moved production to China and renamed ICs to stay competitive.  Python became King Cobra, Viper became Diamondback etc.  I had both, Viper and King Cobra.  I decided to upgrade and considered Sky.  It was too expensive and I went for Acoustic Zen Absolute instead ($650  0.5m XLR used).
I wouldn't buy any cable from ebay (unless it comes from well known store), especially cheap Chinese copy.  You get what you paid for.
@kijanki - the seller said the cables re used and are AQ not copies.  But how do I make sure?  I did try the King Cobra model many months back but they just did not sound good, not open and dark sounding.  The only interest I have in the Sky is that the Vandersteen MP filters use them and I want to make another MP filter copy.  The filters only use one half of the IC or I can just make them with RCA in/out and try any interconnect if I want to.  Any more thoughts?
Yes Just tell the guy that you will take them but you need to
  send the to AQ to verify authenticity.
 Hope you don't get screwed sure sounds fishy for 200 bucks. Best JohnnyR
