Tributaries Series 6 Bi-Amp Speaker Cables - One Pair

Hello.  
I am selling a PAIR of Tributaries Series 6 Bi-Amp Speaker Cables with their BP106 Spring Clip Banana Plugs. Each cable is 16 feet long.     
As you can see in the photos, the cables are in excellent condition and on each, there are four banana clips on one end and two banana clips and two non-terminated ends on the other end of the cable.     
I am selling these items from my late brother's audio setup, so I have no idea about how these were used in terms of his setup, but I'd guess that if required for a certain setup, banana clips or any other sort of clip could be added to the two non-terminated wires on each cable. 
A very nice lady at the Tributaries company helped me spec these cables and also mentioned that they currently sell for $1000 per pair.     
Check my feedback and you'll see that both myself and the cables I'm selling/have sold are legit.     
Thanks for looking.
