Through the different releases of SR fuses, the improvements have been dramatic. The performance jump from the original SR25 to RED fuse was big, and the improvements from the RED to the BLACK fuse were even greater. The improvement from the BLACK to the BLUE fuse is now the most significant performance leap over all prior SR fuse models to date.
New UEF Graphene coating, two years in development, and UEF quantum treatments make the BLUE fuse significantly more Holographic and dynamic than even the incredible SR BLACK fuse. Resolution and musicality are second to none.
