Brand new in box, never used! Three Synergistic Research Orange audio Quantum Fuses. We took them out of the boxes for taking pictures only. They are the 5x20mm Slo-blow version, 1A 250V. The new ORANGE Quantum Fuse is a direct result of technology Synergistic Research developed for the Limited Edition Galileo SX PowerCell. 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 soundstage 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 our highest resolution fuse to date. Retail price is 160 euro, now for 139 euro for one Orange Fuse only. Check our other listings for more interesting items. Free shipping worldwide!
