Most significant fuse performance leap ever!

Through the different releases of Synergistic Research fuses, the improvements have been dramatic. The performance jump from the original SR20 to Red fuse was big, and the improvements from the Red to the Black were even greater. However, the improvement from Black to the Blue fuse is now the most significant performance leap over all prior SR fuse models to date. 

The new SR Blue Quantum Fuse was developed over a two year period and represents our 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 Black. And thanks to a new conditioning process, break-in time is cut in half. In fact a brand new out-of-the-box Blue Fuse should significantly out perform a fully broken-in Black Fuse and it only gets better from there with full performance after 200 hrs of continuous power. After just 24 hours, it already starts to open up. From then, it only gets better and better...

How do fuses alter the sound of your system? For over one hundred years people believed electrons flowed like water through a pipe and that once ‘contaminated’ by miles of wire, there was little or nothing that could be done to ‘clean’ the electricity feeding your components. Consider this: the electricity powering your equipment first propagates through a single fuse. This is why significant gains in sound quality are possible when you insert Blue Fuses into each of your components.

Today physicists understand electrons don’t flow at all but rather propagate in a wave of energy that moves along a conductor with a multitude of factors that alters this wave at the quantum level. To understand how electricity travels without electrons ever leaving their respective atoms it is helpful to consider the spectator ‘wave’ at a football match. Even though you can clearly see a wave pattern moving from spectator to spectator as fans raise and then lower their hands (without hands jumping from one person to the next), so too does electricity ‘move’ without electrons ever leaving their atoms. At Synergistic Research they have isolated key factors that affect how electricity propagates by changing the behavior of electrons through Inductive Quantum Coupling methods they collectively call UEF Tech. In fact, UEF Tech is so powerful even an electrical chain several miles long is fundamentally improved with nothing more than a single fuse engineered with our patented UEF Technology.

What to expect during the burn-in process?
Brand new Blue Fuses tend to outperform fully broken in Black Fuses. With Blue Fuses you can expect a mild burn-in during the first 200-300 hours. During this time you should experience a balancing of the soundstage with improved frequency linearity especially in the mid-range and high frequencies.
We’re so sure you’ll love what Blue Fuses do for your system, we sell them with a no questions asked, 30-day money back guarantee so you can audition Blue Fuses in your system risk-free. Then if you’re not 100% satisfied with your system’s performance on Blue fuses, return the fuses to your dealer in like new condition for a full refund.

Amazing Review by Wiebe
After I fell in love with the SNS, QA and SR plugs I decided to try this fuse.
Just replaced the main glass fuse (one of 5) in my already tuned Marantz NA8005 with this SR blue fuse. Out of the box the sound is better defined, placement of instruments is more precise, the detail that was already there before is now more obvious and easier to hear and as a bonus there is even some more of it! Music is more loose from the speaker and, most surprising, bad recordings sound friendlier and better, as if remastered. Didn't see that coming with my somewhat unforgiving speakers. I didn't think improvements of this level were possible with just one fuse exchange. Nothing short of amazing during the first hours of use, while the burn-in time of this fuse is 200-300 hours. Addictive stuff, I want more! (Posted on 7/13/2019)
A great tweak Review by Pedro Nunes
I switched from Furutech to Synergistic Research Blue fuses on my VTL MB 185 Monoblocks and I found an amazing improvement. (Posted on 10/6/2018)
