Master Fuse is an entirely new kind of Fuse. In the past, SR developed the highest resolution fuse given the current technology while voicing the fuses to complement a maximum number of systems. And for over a decade, as newly developed technologies came online, like new UEF Compounds and new conditioning processes, SR has applied them to the next generation of cutting-edge fuses, usually every two years. Of course, SR were striving for maximum resolution plus the warmth needed for most systems to sound musical. But SR never could press resolution and other sonic traits as far as they could have.

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, SR 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. So you start with a single Master Fuse on your DAC or line conditioner and realize guaranteed results or your money back for the first 30 days. You can then experiment sparingly with additional Master Fuses if you wish to go further. The choice is yours.

Global MSRP $595.00 all sizes. Synergistic Research MASTER Fuses are available in many variants - small (5x20mm), large (6.3x32mm), fast blow (F), slow blow (T) and UK-Plug fuses.

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 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 Purple or Master  Fuse 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.  Synergistic Research isolated key factors that affect how electricity propagates by changing the behavior of electrons through Inductive Quantum Coupling methods SR collectively calls 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 SR's patented UEF Technology.

Rick Becker of Enjoy the Music writes (September 2023):

Synergistic Research MASTER fuse Award

"...the Master fuse is an Olympic jump in both price and sound quality over Synergistic Research's Purple fuse. Using a combination of generic and Purple fuses, my system achieved a huge and undeniable improvement with the addition of only a single Master fuse in a source component...if $595 seems like too much for you, I urge you to take a leap of faith and trust your own ears within your audio system. The 30-day money-back guarantee is there to protect you. Don't be afraid to use it if you're not satisfied. From what I've seen and heard since the pandemic, this should be the hottest product in high-end audio..."

John van Pole of concluded (August 2023):
"...Synergistic Research's Master Fuse is a breakthrough product in accessories for high end audio systems. Dedicated music lovers owning a precious system and demanding dynamic, refined and realistic reproduction of their music, really shortchange themselves by not trying the Master Fuse. With a few Master Fuses, you get a lot more out of your system; it's that simple..."

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."
