Synergistic Research PURPLE Quantum Fuses
The Purple Fuse surpasses Synergistic Research's Orange Fuse with technology initially developed for the state-of-the-art SRX Series cables. In fact, before two last-minute breakthrough SRX technologies, SR could not better the Orange Fuse with its impossible combination of detail and rich harmonic musicality. As a result, SR were set to forgo a new fuse introduction for 2022 as SR could not build anything better sounding than Orange despite two years of trying. It was not until SR finalized two new technologies, namely a three-stage long duration high voltage conditioning process and a brand new UEF compound featuring Graphene, that SR were able to beat the Orange Fuse significantly. Together these new technologies create a larger soundstage with better image focus and higher resolution from a perceived lowering of the noise floor.

Of all the fuse generations and refinements SR has pioneered over the past decade, the new Purple Fuses are by far the best sounding and take the single greatest leap in performance over previous 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.

Available with a 30-day, no-risk money-back guarantee so you can take your time and discover just how mind-bendingly excellent the new Purple Fuse is.


Synergistic Research PURPLE Quantum Fuses are available in many variants - small (5x20mm), large (6.3x32mm), fast blow (F), slow blow (T) and UK-Plug fuses.

Small and large PURPLE fuses are both $199.95 MSRP.

Synergistic Research PURPLE Quantum Fuse

Fantastic fuse! I’m using this in a SMC Audio modified DNA-125. Great combination and the difference after adding the PURPLE Quantum Fuse, considerably smoother, deeper, wider sound stage and better frequency extremes.

Fuse purchase

Perfect My order was processed quickly and shipped out within a day of purchase. I have purchased from Highend Electronics in the past and will continue to do so in the future.

Great Customer Service

Previously, I had nice results with an SR Purple fuse in my Dac LPS. As the SR Purples have gone on sale at Highend, I've been adding fuses for all of my linear power supplies. Even adding to power supplies for my JCAT USB card, routers, and switches has made significant improvements to PC streaming. Every time a new fuse settles in, the sound field gets deeper and wider, with instruments and voices having a bit more separation as well. Purchasing at Highend through their nice website was an absolute breeze. They confirm and ship very quickly. Thanks Alfred!

Magic Upgrade

I replaced three SR purple fuses from dac to amps. The result is amazing. It is directional and will need more time to settle, approximately 40 to 50 hours on my end. Once done, the music will flow. The noise has been significantly reduced, the background is darker, strings are clearer, and deliveres much more balanced sound in all frequiencies . The only potential drawback might be a slight fatigue in listening which may require more burn-in time. Overall, upgrading the fuses is IMO the simplest, most effective, and affordable solution, better than upgrading cables."
