AudioQuest Castle Rock Rare true double biwire 8' spades

AudioQuest Castle Rock speaker cables, a rare true double biwire 8' length, spades, joined into single connection at amp end at my direction when manufactured, 72V DBS. Castle Rock is a current AQ model. As the photos show, "true double biwire" means four separate cables, not a single cable that just has two pairs of spades at the speaker end. My understanding is that if a speaker is designed for biwiring, this is the only way to maximize its potential. This offering is a great way to buy into this otherwise double-expensive route with wires that functionally I feel are indistinguishable from new. These cables were bought new from authorized dealer, I am the first and only owner. In excellent condition, handled carefully at all times (like all my equipment), never a sharp bend. Rated 8 due to a single scuff on an end near spades (red housing) incurred in normal use, meaningless functionally, visible in photo, and marks on the otherwise polished spades due to normal use. Functionally flawless. Used in house with no pets, children or smoking. I used and liked these in my high end system (Vandersteen Model Seven MkII), and am selling only due to having upgraded to a much higher price point. I think these are a "sweet spot" in AQ line. All original packaging--I will ship in the packaging that AudioQuest shipped them to my dealer in and my dealer forwarded them to me. Buyer pays 3% PayPal and actual cost shipping. Low ball offers not welcome.
