Note:  If you are switching from an Orange or Purple fuse to a Master fuse, start by inserting the Master fuse in the same direction as the Master fuse being replaced.  If the Master fuse is not an immediate improvement, flip the Master fuse in the alternate direction.

How 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 feeding your system’s components first propagates through a single fuse. This is why significant gains in sound quality are possible when you insert an SR Black or 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 we’ve isolated key factors that affect how electricity propagates by changing the behavior of electrons through Inductive Quantum Coupling methods we 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.

 We’re so sure you’ll love what SR Fuses do for your system, we sell them with a no questions asked, 30-day money-back guarantee so you can audition SR  Fuses in your system risk-free. Then if you’re not 100% satisfied with your system’s performance on SR  fuses, return the fuses to your dealer in like new condition for a full refund.

Frequently asked questions.

Q: Are fuses directional?

A: Yes, fuses are directional.  Electricity should flow from the left to the right when you view the fuse.  If you do not know the direction of flow you should listen to the fuse inserted in both directions.  One direction will sound more detailed.  This is the correct way.

Q:  Do fuses have a burn in period?

A: Yes, most products have a settling in period.  The first 200-300 hours of use are the most crucial.

Q: Where should I use my Master fuse(s)?

A: To get the most out of our Master Fuses, we suggest starting with one or two fuses in most systems, and possibly more for highly resolving systems. There is no "wrong" component to start with; however, we typically recommend starting "upstream," at the beginning of your signal source (Music Streamer, CD Player, Turntable, Reel to Reel, etc.). From there, we suggest moving on to your digital-to-analog converter or phonostage (if you use one), followed by your preamplifier and then your power amplifier. If you have multiple sources, upgrading the fuse in your preamplifier first can improve the performance of all of your sources."
