Harmonic Tech Truth-Link RCA interconnect cables in very nice condition.  They are 4 meters (13 feet, 10 inches) in length.  I'm not sure these were ever even used. 

They came from a HUGE estate collection of super high end audio/video cables and equipment.  I have many more cables and equipment that I will be listing by the end of December including Harmonic Tech, Analysis Plus and Supra Sword cables, a couple Bedini amps, a Prima Luna Evo 400 amp, Oppo Blu Ray Players, Meridian Tuners, Rega turntable tonearms, and preamps by PS Audio and Audible Illusion.
