Original owner - like new. The gray, dusty looking stuff showing on part of the cable jacket is a photo artifact and not on the cable.
Quad DNA Helix geometry,4 OCC copper conductors (48 strands), with a combined 19AWG. Wireworld's Composilex 2 dielectric. RCAs are silver-clad OFC. Asking $345.
From the WW website:
"Utilizing the same world-class design as its higher priced siblings, Eclipse 7 is the cable for those who refuse to compromise when it comes to preserving the natural timbre of instruments and voices. The Eclipse 7 features Wireworld’s unique DNA Helix® cable design and utilizes Silver-Tube™ plugs for optimal connections."
