Product Description
Product Description
The Infinity Fuse by Vera-Fi Audio is a modern, resettable fuse alternative designed to safeguard high-end audio systems from overcurrent events—without sacrificing performance. It replaces traditional slow- or fast-blow fuses and features user-selectable settings to match your gear’s specific requirements.
Why Traditional Fuses Fall Short
Conventional fuses are single-use and subject to failure from power surges, aging, or vibration. For audiophiles using premium components, this means repeated replacements and inconsistent sonic performance. The Infinity Fuse eliminates those variables.
Precision Fuse Control with DIP Switch Settings
With user-configurable DIP switches, the Infinity Fuse allows you to set your desired behavior:
- Fuse Speed: Choose between Slow Blow (SB) or Fast Acting (FA)
- Current Rating: Options from 1A to 10A
This flexibility allows for fine-tuning based on your gear’s specifications—without trial and error or guesswork.
Built-in Intelligence and LED Monitoring
Smart indicators give you real-time system status:
-
Green ON LED: System is powered
-
SSR LED: Solid-state relay is engaged post inrush delay
-
REL LED: Overcurrent condition detected
- Red FAULT LED: Overcurrent event triggered shutoff
Once tripped, simply power down, resolve the issue, and reconnect. No replacements. No downtime.
Inrush Current Protection That Preserves Longevity
Infinity Fuse limits the dangerous current spikes during startup—common with toroidal transformers. This protects copper windings and helps extend the life of your amplifiers, DACs, and preamps.
Universal Compatibility and Safety
Rated for 85–230V AC / 10A max, with a fused IEC inlet and standard NEMA outlet. Built for indoor use only, it’s fully CE-compliant and meets international safety standards.
Plug It In and Never Look Back
No more burned fuses. No more expensive replacements. The Infinity Fuse gives you peace of mind and consistent performance—with the flexibility your system deserves.
The Infinity Fuse is designed in the USA and assembled in China using only premium-quality components.

So good I am going to order a couple more. I heard a difference when I let the current flow.
What can I say . . .. . . . it's fantastic! My system has never sounded this good!
It's 8:15 a.m., do you know where your Swiss Digital Fuse Box is, I ask myself. It's then my unrealistic mind realizes that the only thing missing from a Swiss Digital Fuse Box is a dog or cat whistle sensor so that it will be present when I whistle.
In half-seriousness, I have in my permanent collection 3 SDFB (6.3 amp x 2 + 2.5 amp x 1) and I have 2 Infinity Fuses---right now. Sure I could use 1 Infinity Fuse in place of 1 6.3 rated SDFB, but garr, I'm feeling like a parent in a supermarket when a beloved family member is... sorta missing. A sorta missing SDFB is unacceptable. So, with an array of Sluggos in my bathrobe pocket, my search continues. I'm about to post pictures and a reward amount on a telephone pole over this.
But first, I'll assign 1 Infinity Fuse to 6.3 amp slo blo mode duty and listen to audio as my search continues. If this is the worst of my problems, I'm having a grossly fine experience with SDFB and Infinity Fuse---and other excellent Vera Fi Products as well.
Firstly I want to say that it is remarkable how much additional performance can be extracted from component by replacing the fuse.
I have been battling sibilance and brightness in my system for some time and I have upgraded power cords, interconnects and fuses. Each change brought about a small improvement, say around 1%.
The addition of the Infinity fuse (replacing a hi-fi tuning supreme) resulted in a 4-5% improvement, not just in the brightness issue, but across all sonic traits.
I should add that the burn in period is lengthy, around 300 hours. Once burned in, My treble was smoother, bas deeper and more controlled and the soundstage was substantially wider, better defined and more immersive, with the space around each instrument/vocal more accurately rendered and textured. The overall sound was more natural and effortless.
Mark and the Vera-fi team included the graphene slug for which I am very grateful. I have no experience with the other slugs, but apparently the graphene is the best. I also used the extreme piggy.
The Infinity fuse is excellent value for money and highly recommended.
The Infinity Fuse did not Work with my Amplifiers.
I have had Great success with the SDFB on my other Components. I am awaiting to Receive the SDFB for my Amplifiers.
It works, and improves the sound.
Failed to work in my system. Have not received a replacement unit in over a month now.
A more cost-effective, user-programmable alternative to the Swiss Digital Fuse Box! And the dip switches allow the user to customize it for amperage and fuse type (slo-blow or fast acting) for compatibility with a variety of devices. You're not limited to a single device (as with the SDFB, which arrives pre-programmed for a specific fuse type and amperage rating), and that frees you to experiment with other equipment, easily helping you decide if you need additional Infinity Fuse units. The only thing necessary for you to do prior to placing your order is to confirm the fuse dimensions and choose the Sluggo (that replaces the fuse) or an upgraded version. And the Infinity Fuse will work with any device with a fuse rating up to 10 amps. Highly recommended -- I've tried it with tube amplifers, DACs, and preamplifiers, and the IF really gets you closer to the music!
3 New Products: My Review:
3 New Products: My Review: The NEW Ver-Fi: Products:
1. Line Noise Black Hole (LNBH),
2. Snub Station Zero (SSZ),
3. Infinity Fuse.
Mark asked me if I would like to try a few of his new products, and as a big time Audiophile tweaker (however my wife would describe me as a nut) I couldn’t resist.
In this review I will try to show that I have tried these units everyway possible within my system (see my profile) to remove any doubts as to how they performed.
First off, using the new Infinity Fuse with a Graphene slug into my Lumin X1 was instant success. This one unit contributed to a much wider soundstage and just a general upgrade in overall sound quality. So, this item will remain, no matter how the rest of the Veri-Fi equipment performs. BTW, it replaced a Synergistic Research Master Fuse.
Then I tried the LNBH and SSZ in my “computer/streaming room”. This room includes my Modem/Router, Etherregen, AfterDark clock, AfterDark linear power supply, and some other sundry items (printer etc.). I let the system stream music for a few days, and after that time, honestly, I could not hear any additional sonic improvement or change of any sort.
So, the next day I relocated the LNBH and SSZ into my audio system. I think I read that these items should be used in Tandem. I am using an AQ Dragon source power cord (from my AQ Niagara 7000 power conditioner) that was plugged directly into my Lumin X1 but now I plugged it into the LNBH and with a short DIY jumper power cord from that unit into the SSZ. And since the Infinity Fuse unit was a definite keeper, I also added an additional short jumper DIY AC cord to plug it into the Lumin X1. I should add that the AC input and outlets are on opposite ends of the devices which made daisy chaining them difficult.
When I played the system with familiar tunes it seemed that the soundstage was pushed way back, kinda sounded like into a tunnel and not as lively as I remembered the tunes before.
So, for “Shts & Giggles” I removed the Veri-Fi previous versions of the “Snubway & Mainstream” devices from the Audio system. (My thinking was perhaps there is too much filtering of the same type). And sure enough, the liveliness returned, so make note of this: the original Snubway and Mainstream do not mesh well with these new products.
Question:
Should I plug all of this directly into the AC wall outlet instead of the AQ Niagara power conditioner 7000?
To answer that question, I then went ahead and plugged the daisy chained trio directly into the dedicated wall outlet. And at first listen, I thought, hmm not bad. But after several back-and-forth trials, I decided that having these units plugged into the AQ 7000 is better. Perhaps different power conditioners may react differently. So, experiment is the word.
After a week of listening to the trio as above, the last and final test would be to return to the beginning, that is; removing the LNBH and SSZ from the system. Note: I have already determined that the Infinity/graphene fuse was a definite instant plus, so it will always remain.
Conclusion:
Well first, I can conclude that that a week of burn/breakin was helpful, as it does for most new equipment, and it may improve further with more use. Then, I have found in the past that using a new item for a period of time, that “new” sound, becomes the standard, (you get used to it) and only after removing it can it be judged on the effectiveness, (if any) good or bad. Do I miss it?
So, after a week of playing my favorite tunes with the LNBH and SSZ devices connected, I then disconnected them and went back to my original set up, (but, again with the Infinity Fuse and the Graphene slug still installed).
At first, I thought the midrange was richer but as I continued listening, I began to realize that the music had lost that “sparkle”. By that I mean, the feeling of extreme openness with images clean and deep with a liveliness that I guess I would say, it no longer sounded “live”.
I then re-connected the LNBH and SSZ devices and ahh, that very open sound returned.
The Downside?
Several short power cord jumpers are needed and as mentioned, daisy chaining them can be difficult.
Sound Quality Wise?
So, my conclusion is that, yes, these devices are a Definite Plus and with whatever is inside them, improved the sound for this old Audiophile. Your music will be released into your room and sparkle the soundstage, enjoy the new performance!
Wow! My system has never sounded better! Highly Recommended!
BTW, my wife still thinks I’m nuts…

The Graphene is a worthwhile upgrade from the copper or brass SLUGGOs. I've got 3 and will order 2 more. Highly recommended!
These Piggy Tails are Excellent. You might think adding them to your favorite Power Cords (I use Rick Schultz Emersion), will be a little of a downgrade but, you will be gaining a HUGE BOOST in performance because of the Sluggos passing on that Sweet Power to your Electronics.
A Win Win all the way.
I had ordered 2 SDFB for my Amps. Due to some confusion, I received the wrong ones. I checked back with Mark and, I was instructed not to use them and to send them back. Vera-Fi will ALWAYS make sure that, you are using the correct Spec items. They took care of me all the way.
The SDFB Really adds that extra layer of Life to my System. There is Excitement when every I listen.
Good Company… they deliver
Let me start out by saying I'm not an audiophile, just an old guy who had the chance to buy some decent speakers. I shopped around watched hours of YouTube evaluations and made my choice. These are very solid speakers that look good anywhere.
As I said, I'm not audiophile but these things blew me away with the room filling sound from a compact size. I also added the Bluetooth amps so I can put them in any room by just plugging them in.
I would recommend these to anyone looking for great sound at a great price.
Fantastic: Mark is the Boss
It took a while to get them, but it was definitely worth the wait. For the price, these were way better sounding than I was expecting. Beautiful heavy wood cabinets, excellent range, tone and quality construction. I don’t think you’d need to, but a nice addition that I purchased was the Vanguard Caldera 12 inch subwoofer. It certainly complimented the system well. I didn’t want to spend a fortune and these fit the bill perfectly.
The customer service response was outstanding and prompt. I haven’t seen this level of personal customer attention in a long time. Highly recommend.
I have mine for a week or so; I have more on order, including the Snubway. But just this one unit has made an impact for the positive, so I am hoping to build on this. It is outlet d, and depending on which outlet it is plugged into, the results can vary, depending on the outlet position in the room. I put my in the Garage by the 1st AC outlet n to the fuse box after reading on that would be a good place for one unit, and they were right, right away the TV Sound bar and the 3 subwoofers connect sounded more dynamic, and the sound was more natural and with more body, what surprised me was on the 2nd level where my Stereo is it made a positive impact there also, I went down and unplugged it and went up and listened again and there was a drop off in presence, body and weight to the music as well as lacking the detail, piano is what I used with a stand up bass, to keep it simple, all sound more real with the one unit plugged into the outlet by the fuse box, so one is staying when I get the others I will built from there and see the extra ones impact, Mark is going to send me a package that he feels will work best for my system, Mark been great even took the time to call me to answer some questions on his products and which would be best for my needs. So try different outlets, let the unit burn-in for a week or so, the only time it hurt the sound was when I put it in the outlet before the Core balanced line conditioner; those two did not play nice together at all, lost mid-bass and bass, sound was thin, but that was the only time, I will try a Snubway there when I receive it. A good product, give it a try.
Really good uplift in soundstage, tonality and dynamics! No doubt about it or placebo!
The sound feels more pure!
At around 300 hrs like clarified by mark , the effect becomes very obvious!
I will probably go one for amp and one for streamer .
Bravo!
