The Swiss Digital Fuse Box has really elevated the sound of my system. More open, more dynamic, more accurate tonal balance, wider and deeper sound stage and greater separation of instruments within.
Aided in introducing all these improvements are the Sluggos that take the place of the fuse in the system when the Swiss Digial Fuse Box is in use. Each is in its way like a tone control imparting a frequency signature. The Copper is big and bold sounding, strong bass and dynamics. The Super Duper is a bit more refined, a lighter and a bit more open sound. The Graphene for my system is like Goldilock's porridge, just right: tight, present bass, treble that sounds natural not etched, presenting dynamic contrasts from micro to macro dynamics that seem musical and connected to the textures of the music, revealing of details in a tapestry of sound where their "noticeableness" seems woven into the tapestry of sound, not sounding exaggerated or unduly quiet.
Yes, the Graphene is the most expensive option. For good reasons. I decided to use one with all four of the Swiss Digital Fuse Boxes I have in my system--adding each one in place of a Copper or Super Duper made an easily heard incremental improvement.
These stands are much more substantial than my previous pangea stands.. and use 4 metal posts instead of the pangeas 3 that were smaller in diameter. The top plate is also much bigger, which I really appreciate. My speakers perfectly fit on the top plate like they were designed for each other!

This is my third Graphene Sluggo for the three components in my audio system that take fuses. With each replacement of the regular fuse with the SDFB and Graphene Sluggo I realized improvement in fidelity.
Everything positive that everyone has said about this device is 100% accurate. I purchased two of these, one for my tubed preamp and another for my tubed DAC. What I heard after making the change was beyond my expectations, cleaner more nuanced sound, no tube noise from the preamp, the music just flows and I find myself listening longer and longer. Very pleased to the point of ordering two more for my mono amps. A simple device that delivers well above its price.
I got in late to the Swiss Digital fuse Box craze. I only tried the Graphene sluggo based on the general consensus by the users that this was the best Sluggo.
The Fuse box is great with the Graphene sluggo. Makes a very nice improvement. I just cannot compare it to the other Sluggos.
Blacker background, more bass, tighter bass, bigger soundstage and to top it all off, my TV picture is clearer. To tell the truth I didn't think this addition would have as much effect on the sound as it has, but I was wrong. Everything I have purchased from Vera-FI has made an improvement in my system.
I have absolutely no doubt. And I didn't think it would be so obvious on the switch. I connected the second to the clock power supply and the third to the power amplifier. Everything is now extremely natural, nuanced and with a lot of depth and expressiveness. I close my eyes and escape. A big thank you for these little wonders which make me rediscover my hifi setup.
I am so impressed with these AC Filters from Verafi Audio they have bettered everything else I have compared them to by a country mile. Even at 10x the price they are an essential addition to any system and dare I say an absolute bargain! I have just placed an order for another pair these are the real deal.
Mainstream replaced a Puron used with Snubway. Did not notice a huge improvement over the Puron. Will keep the Mainstream and use the Puron on a different system.
I now have several of the Main Stream devices. I have found that adding them to the main outlet and the first position of my power conditioner makes a significant improvement in the flow of the music, the noise floor and resolution. Colleagues of mine also use the Swiss fuse box and Snub Nose with excellent results. In this world of diminishing returns for high priced audio gear, it’s nice to see a company offering great products at a fair price.
I have been building various systems over 40 years and can state these AC Filters are extraordinary in performance and dare I say an absolute bargain!
Price to performance value is completely off the charts! Tremendous customer service all the way through, thank you Mark!
I received a generous offer from mark which included extra graphene sluggos, what a great human , I’ve had them in for almost two weeks now , thin sounding, but spacious and full of clarity, not edgy sounding but lacking body, but, there was an underlying bass line that needed further investigation, as I said after the 2 week period, these things filled out and is now producing glorious sound, hype is one thing, but experience is another and boy do these things deliver, it enhances the sound to a degree that no fuse could, in conjunction with the Swiss digital fuse box , the sound is expansive , expressive with clarity, power , prat and a solid bass I didn’t know my amplifier could produce, I knew it was there , but it was only hinted at , yes they do work, my system sounds effortless and at high volume, it just continues to soar , no drawbacks, unless your speakers can’t take it . I am truly amazed by the sdfb it does what it says on the tin , I have 2 and a third on the way, outstanding product, I recommend it without hesitation. Long live Vera-fi !
The Graphene Sluggo delivers exceptional performance in several key aspects. Most notably, it exhibits outstanding micro-dynamics and resolution with minimal coloration. The separation between instruments and musical notes is remarkably precise, creating a clearly defined soundstage with excellent layering and imaging.
The device excels in both initial transient response and decay characteristics, with leading edges showing impressive clarity and trailing notes dispersing naturally into space. Background silence is notably enhanced, contributing to improved instrument positioning and overall immersion. The wide soundstage maintains clarity even with complex electronic music or heavily produced tracks, preserving the richness of accompanying instruments without confusion.
Main Stream works very good together with SnubWay I like these pair.
An example: Listening to Jimmy Smith, "Back at the Chicken Shack" album.
192/24.
With the Main Stream plugged into the house line that powers my network gear, it sort of sounds like I'm front row at a club. I'm hearing the amps and Leslie speaker from close range.
Pull the Main Stream out, and it's like I've moved back 5 rows. Everything still sounds good, but not as distinct as front row.
The Piggy Extreme with a SDFB and Graphene Sluggo made my Musical Fidelity Nu Vista 600 amplifier sound like never before. Bass a bit deeper and more controlled, soundstage deeper, a little bit better stereo image and placing of instruments, more natural sound overall. In short, a noticeable extra improvement of SQ and well worth it. Have a SDFB for my Holo Audio Spring 3 KTE dac as well, and also that again improved the SQ.
I really like both the Snub Way and Main Stream. Significant noise reduction with no loss of detail at all. I like using them so much with my stereo that I bought a second set to for my home theater with excellent results. These are much more effective than the puron, which I moved over to my subwoofer with good effect. Well worth the money at my home!
I am using these with three way 4 ohm sealed speakers. They are very simple to connect and haven't dropped the signal once. Bass is tight and they play loud enough. The sound stage and instrument separation opened up noticeably after many hours of use. Well worth the price!
A truly amazing product, better than any fuse , I am now enjoying the best stereo imaging I’ve ever had, the depth it creates is truly amazing, with width , clarity ,drive and no compromises with the graphene Sluggo , a truly jaw dropping experience , thank you Mark !
At this price point I wasn't expecting much an willing to take a chance. But I am pleased to say that the improvements are noticeable.
I bought 3 of them, 2 for my desktop system and 1 for my surround system, all plugged into the first outlets of power conditioners. They provided clearly audible improvements in sound quality and enhanced my enjoyment of the music, more nuances, better dynamics, bigger soundstage.....For the money, they are an excellent value for upgrading highly resolving systems.
