BriseAudio's proprietary STR7 (Spiral77 structure)

STR7 (Spiral77 structure) was developed in pursuit of the ideal portable audio cable. Without sacrificing sound quality. Without sacrificing flexibility. Aiming for both, BriseAudio's original wire material was developed with the basic structure shown in the schematic diagram and our own know-how. The conductor is made of high-performance high-purity copper, in which state-of-the-art technology is applied, and 196 strands are efficiently arranged in a three-dimensional structure to further demonstrate its true value in portable applications.
