Sluggo - For Use with SDFB

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.

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 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.

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.

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 !

I installed a Swiss Digital Fuse Box in my CD transport, the Audiolab CDT6000. It didn’t take long for me to realise that I had a significant improvement to my CD playback. I had gone straight for the Graphene Sluggo when ordering the SDFB. The music from CD playback was now just more believable. From the low end through the mids and all the way to the high end, every aspect was just so much better. Leading edges to notes are better defined, so are the performers in the sound stage, and they appear to have more space. I have not listened much to my CD collection since I started streaming music but with this upgrade it has suddenly put the silver discs in the spotlight. I am now enjoying re-discovering my collection. The addition of the SDFB/Graphene Sluggo to my CD transport has been a major success. With Vera-Fi’s money back 30 day trial you have nothing to lose and perhaps a lot to gain, so go on, give this a try, highly recommended!

I'm going to purchase more. Made a huge improvement in my system. Also,
Mark is one of the nicest and knowledgeable people I have ever dealt with.
