Sluggo - For Use with SDFB

Replaced all fuses in my system, about 10 in total. A very worthy investment. Thank you Mark

Having already experimented with a range of aftermarket fuses in my system, including the AM Ultimate Premier, AM M1, SR Orange, SR Purple, SR Pink, SR Master, Hifi-Tuning, and Gustard, I have developed a particular fondness for the SR Purple, Pink, and Master fuses, owning multiple units of each. After encountering several positive reviews about the SDFB, I decided to try it paired with the Graphene Sluggo in my Lampizator TRP II DAC.

The Lampizator TRP II is highly responsive to tuning components, making it an ideal candidate for the SDFB. The results were nothing short of remarkable. The soundstage expanded, the dynamics of the music became even more pronounced, and the spatial depth of the audio improved significantly. Additionally, all frequencies seemed to receive a more balanced enhancement. It was as though the SDFB took an already exceptional-sounding system and elevated it across every dimension.

Impressed with the performance, I immediately ordered additional SDFBs. In summary, the SDFB is an outstanding tuning component that delivers impressive results at a very reasonable price, making it a highly recommended upgrade for any audiophile seeking to refine their system.

I’m hesitant to assign a star ranking since my experience could be anything from 3 to 5 as you will see below. In all the many years that I've been seeking the absolute sound, I've always been hard-put to hear what reviewers called jaw-dropping improvements whenever they added some new something to their systems. I have the same difficulty with wines and with coffees; I simply don't pick up on the subtle differences that apparently are obvious to other people. And so it has been with the SDFB and the three different Sluggos I have used with it. To be fair my Gato 150AE and Aerial 6Ts already sounded far better to me than any amp/speaker combo that I have had in the past, so that it would have been asking a lot to for me to expect any profound improvement by adding something else to the mix. I like to think that I heard something new when I plugged in the SDFB with the copper Sluggo I started with, yet my jaw remained where it has always been. Don’t get me wrong -- everything sounded really good, just not bowl-me-over good. The thing I did hear, however, was a new glint, twang, sharpness (I’m not really sure how to describe it), something whenever a singer or a brass instrument hit high notes. Nevertheless, I didn’t want to risk losing even a subtle improvement by returning it within the 30-day window that Verifi graciously allows its customers. After a couple of months’ listening, I went back to their website and discovered that, according to Verifi’s description of it, I probably should have ordered the Super Sluggo to get more warmth from the fuse box. Hoping it might solve the problem with the sharpness I heard in high notes, I ordered a Super Sluggo. Unfortunately I honestly heard no difference between the two Sluggos. I suppose I should have returned it for a refund at the time, but for 30 bucks I didn’t want to look like a complete cheapskate. Another few months passed before I decided to go for broke with a Graphene Sluggo. (The discount at the time and Verifi’s praiseworthy return policy decided it for me.) I am happy to report that the Graphene so far seems to have resolved the harshness I was hearing with the highs in my system. As I said before, I don’t have the discriminating hearing that other listeners seem to have when they describe seismic improvements with every new addition to their systems. Your experience could be much different from mine. In all I’m happy with the way my system sounds now and while I might be slow to appreciate improvements that the SDFB and Graphene Sluggo offer, I wouldn’t remove them from the whole on any count.

The first 30 hours I heard the potential but the tone seemed off. Now about 60 hours in I am totally blown away! The biggest improvement is the soundstage and imaging. The SDFB on my amp has freed the music from my speakers. It is just there, in front of you. The speakers disappear (hard to do with 5 foot tall, 2 feet wide Acoustats). The depth is incredible! The background is quiet and black, details just jump out of the mix. Amp seems more powerful, more dynamic.
I still think it would be even better without having to use another separate power cord, and I intend to try to use adapters with the SDFB to compare against the Piggy. But the Extreme Piggy is very good.
This is one of 5he best tweaks I have tried. Highly recommended!

This fuse box in one word is magic ! More air , micro dynamic , details... without negative aspects . Incredible .

Make my DAC more clear and more powerful with low costs, I like it.

Dieser Schweizer digitaler Sicherungskasten bedeutet ein update wie eine Verbesserung einer Komponente.Es ist unglaublich wie dieser Kasten wirkt.Es wird wohl nicht bei einem bleiben.Gratulation!

Purchased 3 extreme piggy power cables , incredible craftsmanship, also because they are 2 ft length they allow the power conditioner and Swiss Digital to sit on the floor properly.
I purchased the extremes as they match my extreme power cords, of which I am super Happy with and yes they DO MAKE A Difference ! You can't go wrong with this type of perfection for the price.

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.

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.
