Dana Cables Sapphire 7ft biwire pair

I have a mint condition bi-wire 7 ft pair of Dana Cables Sapphire. These were purchased last year when they were top of the line Diamond model. As of January 1st, Dana Cables changed their models by introducing an even better model and these became Sapphire. If you look at the cables, you can see the 'sparkling' black on the wires, typical of Diamond line. These are 4 gauge 4 weave cables that have been gathering rave reviews. Do a search and see what people are saying about their entry level models and higher end ones. Do a search on positive feedback page...
When I purchased them last year, I didn't expect them to have such a big impact in the quality of sound. Boy, was I wrong!!! Smooth vocals, quiet background, deep bass, and the music has a way of flowing from the speakers.
These cables are a paradigm shift in the speaker cable industry! Not only they look cool, they sound better than cables costing 3-5 times this much! Here is your chance of owning a fabulous pair of speaker cables! I'm only selling to move up their line.

I'll include shipping in conus (they're quite heavy!) and paypal at my asking price. International buyers, please add $50 for shipping. No low ballers, no trades. Check my feedback.

Thank you for looking and happy listening!
