This is a 17-foot pair of Acoustic Zen Satori speaker cables. They are spade-terminated on both ends.
"The Satori speaker cable is made of an incrementally layered, multiple strand, non-extruded, 10 awg 6N zero crystal copper. It is designed for amplified signal delivery in perfect phase and with absolute spectral and tonal coherence.
We believe there is none better. These are state of the art speaker cables that achieve extraordinary imaging, ambient detail and soundstage palpability." -- Acoustic Zen
I'm the second owner, and they were purchased by me in mint condition in 2005. There is some cracking of the heat shrink tubing around the spades, and the covering is fraying in some places from rubbing against itself.
These are wonderful cables and the sweet spot in the Acoustic Zen lineup.
