Brand new in box, never used! Three Synergistic Research Purple audio Quantum Fuses. We took them out of the boxes for taking pictures only. They are the 5x20mm Slo-blow version, 10A 250V. The new Purple Fuse surpasses the Orange Fuse with technology initially developed for the state-of-the-art SRX Series cables. Compared to the Orange Fuse, the Purple Fuse creates a larger soundstage with better image focus and higher resolution from a perceived lowering of the noise floor. They take the single greatest leap in performance over previous fuse generations. All aspects of subjective sound quality get enhanced, including natural sound where instruments and vocals sound inherently right, dynamics, low-level detail, high-frequency extension, and smoothness all take a massive leap forward. Retail price is 200 euro, now for 169 euro for one Purple Fuse only. Check our other listings for more interesting items. Free shipping worldwide!
