Make the best out of your Hi-Fi System with Vera-Fi Audio. We deliver products to a NEED and we make products that bring JOY to everyone.

Tom Gibbs - Vera Link
"Well, the good news is shockingly that the Vera-Link amps will drive the LRS+ without any issues, at near-reference levels, and with a surprising level of musicality." "You'll have to take my word for it -- the $199 Vera-Links will drive just about anything to near-reference sound levels -- and sound shockingly good while doing it!"

Jeff - Tone Audio
"Other than the fact that these amplifiers are very musical, play loud without distortion, and have much less grunge than you would ever expect from a $200 pair of monoblocks (albeit Barbie Dream House sized monoblocks) there’s not much more to tell. They sound great, are unobtrusive, and offer no-fuss, no muss setup." "The most fun you can have for $199!"

Tom Gibbs - SDFB w/ Graphene Sluggo
"The use of Graphene in the latest iteration of Vera-Fi Audio's new Sluggo for the Swiss Digital Fuse Box allows for a substantial leap forward in overall performance."

Hifi Audio Guru
I’ll admit to a bit of skepticism when I was approached with this product, but the Swiss Digital FUSE BOX delivered on its promises and then some. I’ve always said that in an amplifier, power supply is everything, this was clear going all the way back to early Hi-Fi when we would build huge outboard power supplies as performance mods. With modern audio products trying to run more efficiently it only makes sense that the limiting factor is the amount of power going into the power supply, and as noted above the weakest link in the power chain is the fuse.

Positive Feedback - Vanguard Scout
"The Vanguard Scout has the potential to be a true world-beater, and if you're willing to give them the necessary break-in time and exercise careful amplifier matching for a high-end system implementation, I think you'll be every bit as impressed as I am. And in my system in tandem with the Caldera 10 subwoofer—which they blend seamlessly with—the combination easily took my KLH Model Five loudspeakers ($2500 MSRP) to task. After the fully broken-in Scout/Caldera combo took the stage, I never felt I was missing anything the Model Five brought to the table."

So…
I plugged the Mainstream and Subway, sat and, well nothing! No change at all. A little disappointed to say the least. And then, literally a couple minutes later it began and increased over the rest of the evening. By the end of the week I was astounded and promptly ordered two more! Improvements across the board, most noticeable was a greater musicality, richness and body to the music. More natural, less harsh or forced.
When the second set arrived it was the same thing. With two pairs in my system now, it’s a component level change. Once of the best improvements for the costs ever. Thank you

I had check-boxed fuses off as a facet I wouldn't bother toiling over after 'sampling' a couple Hifi fuses and coming back to the stock fuse the manufacturer supplied and used while designing and trialing their product on both counts.
In short, I had come to the conclusion that Hifi fuses are not for me as both added coloration.
Enter the SFDB. It works without adding coloration. Everything opens up, is more resolved and dynamic, and with a noticeable drop in 'digitus'. I am not a believer in Hifi fuses, but can hence highly recommend the SFDB.
Additionally, communication with Mark, and others at Vera-Fi Audio, has been a pleasure.

After integrating both the SnubWay and Main Stream into my system for an extended period, I can confidently say they have become indispensable components in my setup. From the very beginning, the improvements in low-frequency articulation and control were immediately apparent. The bass not only gained in weight and presence but also exhibited a remarkable refinement, offering better layering and definition without overwhelming the rest of the spectrum.
The SnubWay contributes by subtly reducing background noise, allowing micro-details and textural nuances to surface more effortlessly. Meanwhile, the Main Stream enhances the power delivery with a natural, unforced energy, resulting in an organic flow to the music that feels both more vivid and coherent.
What impresses me most is the way these two devices elevate the emotional engagement of listening sessions. The system now breathes more easily, with a blacker background, sharper imaging, and a more lifelike presentation across genres—from classical orchestration to complex jazz ensembles.
It is rare to encounter accessories that make such a profound impact without altering the core character of the system. I am truly grateful to Mark for offering these outstanding products, which have taken my system's performance to a new level of musical realism and immersion.

I purchased the this little subwoofer after watching several YouTube videos where the reviewers were impressed by the build quality and sound. With a 3 year warranty, I felt I had nothing to lose, so I bought it. When I hooked it up, something wasn’t right, so I called Veri-Fi Audio customer service and left a message. The owner of the company soon returned my call and walked me through some steps which had the sub working perfectly. I am very happy with the sound of this unit and plan to keep it. I am even more impressed with the service I received. Dedication to customer satisfaction is rare these days, and Mark from Veri-Fi Audio has made me a life-long fan! I will be buying more products from them soon.

MIT Z-1 and Blue Circle BC86. Highly recommended!

That's nothing to be said. Fantastic products and still purchase more.

I wasn't sure what to expect when I initially ordered a SDFB and graphene sluggo for my DAC. After reading many positive user reviews and speaking to a dealer in my area who recommended them highly, I decided to take a chance and place an order with Mark.
After an easy installation process, I was quite shocked with the sound improvement. Vocals are now much more present, improved separation, soundstage and depth/layering. The music flows from my speakers with a relaxed ease. I was so impressed with the results, I immediately ordered 3 more. One for my preamp, power amp and switch. Each fuse box made noticeable improvements in my system, especially the ones on my DAC and switch. Very impressive performance improvement for a relatively low cost compared to the other components in my system. The only negative thing I can say about the fuse box is if you try one, you may end up wanting one for each component in your system!
Everything you've read but Mark in the other reviews is absolutely true. He's a truly wonderful guy to deal with. He was always quick to respond to all my messages and went out of his way to ensure I got the properly configured fuse boxes for each of my components. If you have any questions, don't hesitate to send him a message, he's a real pleasure to deal with.
Vera-Fi Audio has quickly become one of my favourite Hi-Fi companies in 2025. Highly recommended!

I received fuses a month ago for three Pass Lab amplifiers used in dual amplification: two Pass 60.5 XA for low frequencies and one Pass 30.5 XA for high frequencies. After changing the fuses I can say that the swisse box do a very good job. At first I used them with gold sluggoes, already with very good results, at a later time I replaced them with graphene sluggoes (obtained on very good terms and being able to take advantage of an offer although I had bought them a few weeks earlier). Thank you Mark I appreciated this sales ethic in a profit-driven world.
I must preface this by saying that what convinced me to purchase, beyond the enthusiastic comments I read on these pages, was the logic behind this project. Those who, like me, compose their systems with countless electrical devices often get the result of both enhancement and degradation. In addition to EMI and RFI interference, ground loops, and noise generated by each device that is added, one should not forget the degradation caused by these funnels that are the fuses that actually multiply the bottlenecks in the acoustic signal path in proportion to their use: in my case a cascade of switches, a Clock, a streamer, a DCC, a converter, a preamplifier, and three power amplifiers. The project of removing these bottlenecks seemed to me a simple and enlightened idea to pursue the most neutral position, which is that of a device with the best possible power supply. I will give below some suggestions to eliminate in my opinion the risks due to the suppression of the physical fuse with the electronic one.
I waited a break-in of a hundred hours before moving on to a critical listening of the results obtained. Not only were the changes already convincing, but there was further obvious room for progress with the graphene sluggo version. After swapping the old Synergestic fuses (orange and purple in my case) for the swisse fuses with the gold sluggoes, I caught a better homogenization between the two frequency bands in the bi-amplification. Another rather noticeable nuance emerged in the spatial delineation of instruments, particularly voices. The previous fuses seemed to enhance the midrange or treble depending on the model, but at the expense of the edges of the instruments and voices, which found themselves no longer placed in a delimited space relative to other voices or instruments. In other words, it seemed to me that in the old fuses the greater efficiency was achieved at the expense of the separation and contours of the elements on the soundstage being less precise. With some recordings, such as Pergolesi's Stabat mater in Abbado's recording, the voices of Margaret Marshall and Lucia Valentini Terrani are now better separated and more similar to the reference obtained in headphones. With the graphene sluggoes the whole range and in particular the basses have improved in articulation, speed and in the case of the basses have become tighter and more dynamic. Very often we remedy one of these degradations by unbalancing other parameters. In other words, we correct an alleged imbalance by introducing other imbalances in a chain of errors that balance each other out. The temptation, needless to say, is to proceed with the elimination of the other bottlenecks, wallet permitting.
A word of advice to finish up : in the use of fused swisse in amplifiers or other devices with stand-bye set-up precautions are to be considered. Due to the fact that swisse fuses take a few seconds before the green light comes on making the defense of your hi-fi devices effective, following a blackout of the mains or home electrical panel, the stand-bye position could result in power arriving before the electronic fuse is activated. I therefore recommend that you take the precaution of turning the device off, wait for the light to change to green before putting it on standby.
Thank you in any case to Mark and his team for the pleasure this new listening brings me.

Very pleased with the Graphene Sluggo. Not fully cooked yet and might take a while longer as I don't leave my amp powered up, but the easiest way to put it is smooth with an increase of information. Pleased enough that I will be ordering for the rest of my gear in the near future.

WOW! 💥 I added the Main Stream unit first. After a good amount of break-in time, I started hearing the backgrounds in the music sound quieter. Instruments are a bit more focused in their own space. A subtle but noticeable improvement overall. Now I decided to try out the SnubWay. 48 hours in, no real change in things. Fast forward to about 500 hours of being in my stereo system (with the MainStream still in place) and I cannot believe what I am hearing! I have a much bigger soundstage right-to-left and the same for depth front-to-back. There's a greater separation of instruments & voices and yet there's more layering and detail in between. Anyone who cares about their music and optimizing the way your stereo sounds needs to contact Mark L. Schifter at Vera-Fi Audio. Of course, YMMV in your system. Tell Mark that I sent you!

Fantastic. Amplifier producing bigger sound stage and instrument separation. More resolution but not harsh. Less tense, more musical. Makes me want to listen.

This is my second Snubwayand I have had one for my audio system and it made an audible improvement. This second one is for my new tv and soundbar. Again a visual and audible improvement. Smoother clearer sound and sharper and clearer picture. Well worth the modest cost. Highly recommended!

Include instruction to handle graphene sluggo with minimum contact when installing

With so many portable plug-in noise filters on the market, some of which I have tried and implemented in my system(s), I was leery of the SnubWay but decided to give it a try. I was not too impressed at first when implemented in my 2nd system as it caused an upper frequency glare when placed in the outlets in the listening room. With some experimentation, it became clear that placement was the key to extracting its full potential with one place being most effective and that was in the dining area where we have our laptops. Placing a SnubWay on that circuit had a substantial improvement on the systems resolution and noise floor. Unplugging the laptops was also shown to reveal additional reduction in noise. Highly recommended but experimenting with placement in one's home is key to extracting its full potential.
