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.

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…

"First, I'd like to thank **Mr. Ace**. He was a great help with the delivery.
The **SnubWay - Noise Defender** has enhanced the audio system. A new level of sophistication has been added to the system, which was previously a straightforward 'Main Stream' setup.
Firstly, I feel like the **soundstage is wider**.
And I feel like it has captured the **subtle vibrations and noise**.
Frankly, I had been briefly tempted by Chinese-made products due to their price advantage.
However, **vera-fi-audiollc** clearly demonstrated the **technical gap** between those products and this one.
Thank you."
This is my first Hi-fi set of speakers I have ever bought. Before this, I listened to BOSE speakers.
WOW.... what an upgrade these Vanguard scout speakers are!!
I had to wait a couple months to get my order (because of tariffs), but Mark and his team were really amazing at answering all of my questions and updating me with the progress of my order.
I ordered the Caldera 10 sub, vera-link amps, and the scouts and Mark helped me to understand how to plug the vera-links bluetooth amps into the subwoofer through the high-pass input and output through the high-pass directly to the right scout speaker and it works like a charm! I couldn't be happier!
You will see two pics in my review of the back of the right vanguard scout speaker, because I wanted to show you that if you have to peel the velcro off of your speaker and place it elsewhere, it doesn't leave any residue to clean up! It's not a huge deal, but it certainly made my life easier.
I am a fan for life and will be ordering some of the new things they are working on in the future!
I purchased three Caldera 10's to go with my three pairs of Scouts. I love them, so I purchased 4 more to get small rooms 2.1 & large rooms a 2.2. I love speaker systems but I haven't had a good set up for years. I looked into this for months. I didn't know what my sound system was missing till I got the lower end filled in.
Great speakers, right in my budget. I purchased one pair, broke them in, loved them, and then purchased 2 more pairs. I had the option of ceiling speakers but bookshelf sound so much better. The Scouts allowed me to get great sound and budget. I have them in several rooms now. 2.2 in the main rooms and 2.1 in the small rooms. When connecting a Caldera 10 it was suggested to put a HPF 70h on the Scouts. I haven’t been able to find a good low cost 70h, closest so far is 80h $25. I purchased (3) pairs of Scouts and (7) Caldera 10. So HPF is important to focus more on the mid and high’s. Really really like Vera-Fi Scouts and Caldera’s!!!
Great product , great prices and good follow up when required.
Good price, looks great, well made -suits the scouts perfectly
I had my eyes on a Caldera 10 subwoofer for quite a while before I decided to take the plunge, but I'm really glad that I did. I initially had reservations for how low the price was for what it claimed it could do, but eventually a sale came along that was a little too good to resist and I purchased it for $149.
I imagine myself and quite a few other people ended up ordering around this time and it took some time before my order was fulfilled. Additionally, there were significant delays in shipments due in part to ongoing changes to US import policies, but Vera-Fi diligently kept me updated throughout the process, even responding to my emails I sent with questions. In hindsight, I am glad I was patient and waited to receive mine.
Though it took some time, in the end, I received a cute little compact subwoofer to pair with my budget living room setup and have been very pleased with how musical and quick it is, as well as how much it filled out and enriched the music for a pair of smaller bookshelf speakers. I don't think there is a better budget sub for a 2.1 stereo setup for this price. The Caldera 10 is a product that knows what it is and does it damn well.
Highly Recommended.
Caldera 10 Duo paired with Magnat monitor supreme. They blend well, have great audio quality, nice looking & hefty build. My system sounds beautiful. I have the calderas set just over 1/4 volume and the bass is vibrating the gutters on my house.
I guess I happened to order as everyone else realized the bang for your buck deal Vera-fi is offering here. I had to try and be patient and wait for the backorder to be fulfilled. As I waited I recieved excellent communication from Mark and his crew.
I wouldnt hesitate to refer a friend.
Im super happy 🤘😁🤘
Thanks Vera-fi !!!
When I added the LNBH and SSZ to my system, I installed them together, so it’s impossible for me to separate their individual contributions. After a long run-in period, the changes became so compelling that I found myself staying up late, revisiting every song I’ve ever loved.
One of the most striking improvements was the disappearance of noise-related limitations. With these two in place, details that were previously buried in the mix became clearly audible. I could hear the subtle sounds of a vocalist taking a breath or even swallowing, which added an incredible sense of realism to the performance.
The overall imaging feels more precise, with every element in the soundstage locked in place. Music flows effortlessly, and the presentation is so engaging that it’s hard to step away from the listening chair. This pairing improved the technical side of my system while also bringing a level of musical connection that keeps me listening for hours.
I recently replaced the stock fuses in both my SSZ and Tempus PSU with the Graphene Sluggo.
Even at the start there was a sense that something had shifted, but this is not the kind of upgrade that shows everything in the first hour. In my case it really came into its own after about 300 hours. The first 50 hours the treble had a slightly tighter character and the mid-bass felt restrained. Around 150 hours the presentation started to relax, with better flow and more natural layering. By 300 hours dynamics felt settled, micro-details became more apparent, and the whole system sounded more connected.
What stood out most to me was the neutrality and transparency. It does not push the tonal balance in any direction, it simply lets the system speak for itself. Highs extend cleanly without harshness, keeping fine texture and air. The midrange has a natural presence with good retrieval of subtle detail. Bass is well controlled, evenly weighted, and separated with clarity.
On the SSZ, highs became smoother while keeping resolution, and the soundstage felt more open in both width and depth. Vocals gained more dimensionality compared to the stock fuse. On the Tempus PSU, tonal balance stayed consistent, but resolution improved across the range, making instrument separation easier to follow.
Mark at Vera-Fi has been great to talk to. Every question I asked was answered with detail and warmth, which made the whole experience more positive.
After this I plan to gradually replace all the fuses in my system with the Graphene Sluggo. For anyone using SSZ or Tempus PSU who wants more resolution and detail without altering the system character, this could be worth considering.
