Best speaker wire so far, the Triple C SPC- AV 1.0 is better than OCC copper. I replaced the wire inside of my full range horn speaker with SPC-Av. Very clean ,more balanced from top to bottom ,very smooth and on the warmer side. More information on recordings revealed and bigger 3 D sound stage.Worth every penny. My speaker now are at much higher grade quality in sound. Next will be interconnect project and speaker cable.Good store .I recommend the cable and store , no hesitation.
