-One sold, so only one left in stock- New in box with high discount, never used! Two Synergistic Research Master audio Quantum Fuses. We took them out of the boxes for taking pictures only. They are the 5x20mm Slow-blow version, 6.3A 250V. Master Fuse is an entirely new kind of Fuse. Enter Master Fuse; the first Synergistic Research fuse developed expressly for full resolution, dynamics, soundstaging, speed, and impact without the need to create musicality as a system-wide fuse loom. Instead, they engineered Master Fuse to work alongside Purple and Orange fuses to create dramatic new levels of sonic realism, featuring wall-to-wall, floor-to-ceiling soundstaging with unparalleled resolution, dynamics, and frequency extension. Best of all, most systems will not benefit from more than one or possibly two Master Fuses in an otherwise complete loom of Purple and or Orange fuses. Retail price is 599 euro, now for 499 euro for one Master Fuse only. Check our other listings for more interesting items. Free shipping worldwide!
