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.

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…

I bought these because I have been in love with Rosewood veneer since I first saw it as an extra cost option for some $5000 speakers in the '90s. Never expected to be able to afford a pair of Rosewood veneered speakers, but then found these for under $300. I pulled the trigger, ASAP.
When they arrived, I gave them >50 hours of 85dB in room playback of the radio with them facing each other under a comforter and wired out of phase to damp down the noise. After this, I gave them a listen. Beautiful, and they sound spectacular for their price point. I felt like I won the lottery; a scratcher, not the PowerBall, but still :) I was used to a bookshelf pair w/ lite mid-bass response and slightly "crisp" highs, and these (in direct comparison) had excellent mid-bass response and are just a bit laid-back in the very highest registers to my ears. I use them with a 500-watt RMS ported 12" subwoofer crossed over at 100Hz and get good output from them with an 80-watt per channel RMS amp. Like easy, no strain, >90dB at the listening position 12' away kind of "good output". For movies, tv, and music. Plenty for me.
If you like beautiful speakers, good sound (though not detail monsters like the AMT-tweeter based speakers I have in the bedroom), and spectacular value don't be afraid to pull the trigger on these Vanguard Scouts. Just please don't expect "giant killing" sound quality for under $300, and I promise you'll be happy with your purchase.
I’ve never had good speakers to listen to music on, so this was a big leap for me. I bought the Vera link combo and the 10” caldera to go with them. Mark has answered every question of mine personally and he advised that I connect the vera-link to the high pass input and then out put with some cables to the speaker and it works like a charm! Even though I am listening to music through my bluetooth on my iPhone, it sounds absolutely amazing!!
Excellent built quality, a ported sub that sounds closer to sealed sub and for only 348 euros? Insane but true, the Caldera 12 will sound just as good in my room for music or home theater, i cant recommend this sub enough! Go dual for bombastic room filling low notes imo. The only gripe i have is the auto on off which turns the sub off after only 10 seconds, i would recommend at least 1+ minute of inactivity to turn off so lets hope they boys in the lab will sort this out on the next batches! Excellent job Vera Fi team!
"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.
