Harmonic Tech Pro Silway II RCA interconnect cables in very nice condition.  They are 1.83 meters (6 feet) 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.
