Recommended Plug Adapters

The Snub Station Zero, Infinity Fuse and Line Noise Black Hole do not support 3-Prong Schuko with grounding pins currently.

But just in case you need grounding, here are adapters we recommend for you to use:

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.

User-programmable Alternative to the Swiss Digital Fuse Box!!

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: 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…
