Synergistic Research Orange High-End Fuses

The revolutionary new SR Orange Quantum Fuse was developed over a two year period and represents Synergistic Research’s 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 Blue. And thanks to a new conditioning process, break-in time is cut in half.


Synergistic Research’s Orange range of fuses are their latest and greatest breakthrough. Synergistic Fuses are available as both ‘Fast-blow’ and ‘Slow-blow’ options and are designed for a wide range of Hi-Fi and AV equipment. The Fast-blow fuses are most commonly found in everyday electronic equipment. They are less tolerant to high current passing through, meaning the fuse will blow easier but it will protect your equipment in the process. Fast-blow fuses should be used where the equipment is sensitive to the flow of electricity, allowing a prompt reaction to any surges in order to protect your equipment. For example, a Fast-blow fuse can be used in Pre-Amps, DACs and TVs. When installing your new fuse, please ensure you test the fuse in both directions as they are directional from left to right. When the fuse is inserted in the correct direction, it is designed to sound more detailed.

The new ORANGE Quantum Fuse is a direct result of technology Synergistic Research first developed for their Limited Edition Galileo SX Power-Cell. At its core are new UEF Technologies and a completely new multi-stage high voltage treatment process for the lowest noise floor of any fuse they have ever manufactured. In fact, ORANGE is by far the most significant leap in performance across five fuse generations. Subjective improvements include better timbral accuracy where separate instruments and voices take on a new degree of life-like realism. Other benefits over prior SR fuses include a larger sound-stage with greater depth, width, and front-to-back layering. Musicality or the presence of increased detail without a hint of fatigue is off the charts for extended listening that is never harsh despite being their highest resolution fuse to date.
