Ok. These are homemade. Soldered with Mundorf Silver/Gold solder and the RCA connectors are the same ones used by Supra but direct from WBT so they are a different color. Yah . . . bootleg interconnects. I shortened another pair to make this for a short run between a solid state preamp and amp about three years ago. Used them for about a year and they have been sitting since. I'm putting these up for sale because they are quite useful if you are stacking something and the sound quality is "class A". Could make a big difference for someone for only 200 clams. Price is firm because they really are nice to have around. Paypal and shipping in USA is already included in price. International buyers pay actual shipping.
