The new SR BLUE Quantum Fuse was developed over a two year period and represents our most advanced UEF Technology to date. At its heart is a completely new UEF / Graphene coating that delivers a dramatic increase in resolution and holographic realism over SR Black. And thanks to a new conditioning process, break-in time is cut in half. In fact a brand new out-of-the-box BLUE Fuse should significantly out perform a fully broken-in BLACK Fuse and it only gets better from there with full performance after 200 hrs of continues power.
