The one fuse to rule them all

Master Fuse is an entirely new kind of fuse. In the past Synergistic Research developed the highest resolution fuse given the current technology while voicing their 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, they have applied them to the next generation of cutting-edge fuses, usually every two years. Of course, SR is striving for maximum resolution plus the warmth needed for most systems to sound musical. Never before Synergistic research was able to press resolution and other sonic traits as far as they have now.

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, dynamicss 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.

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.

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 Master Fuses directional?
A: Yes, all 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, almost all 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.

Fantastic product Review by Norbert
My system (Emitter II exclusive, Avantgarde Acoustic Primo, T + A MP 3100 HV) is fully tuned with SR products ( Power cell SX, Ground block Galileo SX, orange and purple fuses, GTCs and ECTs throughout the components, XOTs at the speakers and FEQ Carbon with Tuning Module)

Each tuning step down the road improved the sound of my system to a much higher level in total and I only can recommend to everybody who has a higher up system to go this way, when you rally what to hear what your system is capable of.

My last step was to install one Master Fuse in my T + A MP 3100. The streamer needs two (the second one is on its way) I am amazed what only this one fuse did to the sound already and the fuse is only one day in my system.
Every aspect of the sound ( clarity, details, dynamics, soundstage, bass, mid and high frequencies) got pushed to a totally different level and now really brings the maximum out of every single tuning step as well shows the full capabilities these high level components in my system have hidden so far.

The sound was never so crystal clear with soo much air around and absolutely nothing stands anymore between the speaker and you in your listening position.

It seems like this Master Fuse is just putting everything together and can only highly recommend to test one!
