Kimber Kable Select

If you've never been exposed to the internet market, you should start selling/buying some cheap stuff, get some feedback from buyers and than place for sale something more serious.
 How did you find out about Audiogon?

Emojo, as has been alluded to, there are lots of scams in the audio world as there are in the rest of the world.  There are many counterfeit products, Kimber included.  Since the items were purchased in an audio store I would recommend you take them back there or at least contact them to see if they would sell on consignment. If your story is legit (not saying it isn't) then this would be the easiest for you. 

30% off would be a fair place to begin, since what you have is still a current Kimber offering. That’s about what The Cable Company asks for their used 3035s (http://www.usedcable.com/Catalog/Speaker-Cables) There are those that counterfeit Kimber products, so- list the serial numbers and(hopefully) pics of the original packaging/air-tight box, documents and mention from whom they were purchased.  Regarding the above url:  click on the, "filter by manufacturer" tab and find Kimber, for price references.

Thanks for the imput rodman99999. I didn't know about fraud and especially counterfit products. I'm going to back out now and ruminate. I will contact Audio Concepts and get info from them as well.
 Again thanks.

Rodman99999, these cables are 10 years old, doubt he will sell for 70% of retail. I would suspect closer to 50% of retail.  You can try for 70%, but don't expect that much.  These cables are pretty common on the used market.
