FUSE BOX delivers perfect protection and superior sound

This is gold, Jerry! GOLD!!!

Laugh at the first couple comments calling it a scam. There’s a 30 day no questions asked money back guarantee. I ordered a pair and I have zero intent to go back to using an amplifier without the SDFB installed in-line in the power path. I am completely satisfied with the purchase and have no regrets.

Good Morning 

I am in receipt of an exceptional review that was posted on the Decware Forum.

I contacted the author and asked his permission to post a link to his thoughts here. He was gracious in allowing me to do so. 

Thanks - Mark

@skucie 

Good read here - thank you

We have some solid material samples coming as well as some electroplated samples that our team wants me to hear

Woefully behind on this - been promising groovy sauce on the Decware thread for weeks now. Did not realize that my vendor is sending all of these at once 

FB is making waves for real

I actually coated the copper slug with a new product (that I think is limited) by Rick Shultz called "Pro" that I was asked to try.

It seemed to add a little more in the way of quietness to the sound.

But I still think by-passing the fuse holder would be the best. I will try this soon.

@skucie 

Thanks for going the extra mile. After you clean all your contacts (I used isoprophol) then use Mad Scientist Audio Graphene Contact enhancer SPARINGLY

I spent a few minutes polishing the copper sluggos with a connoisseur’s polishing cloth (gold) until they were visibly shinier and installed them earlier this afternoon.

My system is sounding better than ever with the polished copper, making the brass sound lifeless by comparison. I’ve had a list of errands to do today and it’s now 7:50 PM and I’m listening through my 4th album.

My Vandersteen speakers are producing bass I didn’t know they were capable of in my large listening room. Deep, tuneful bass I can feel in my chest. The impact is much more noticeable than it was before.

The soundstage is clearly defined from front to back and left to right, better than I’ve ever heard it. I feel like I’m hearing the rear corners of the stage with less distortion than ever.

related thoughts:

-The power cables feeding my best equipment (and plugged into the fuse box) are quite a bit better and more costly than the ones I’m running into the fuse boxes. I expect there is more to be gained there, albeit at a much higher cost than the fuse box itself. It’s worth doing though, the price/performance ratio on the fuse box is better than every other aftermarket product I have in my system.

-As someone mentioned above, I feel that the fuse holder in the equipment is, itself, a big part of the problem. A high quality jumper wire bypassing the fuse holder would almost certainly lead to a substantial improvement. I’m not comfortable doing that to my favorite gear (yet, anyway).

-My next step is to apply some contact enhancer and see what that does. I’m planning to use this, unless anyone has an argument for something else performing better.

Place an Alpha E-card (PerfectPath Technologies) on or under Fuse Box.  Amazing.

Guys,

Added another 1A SB Fuse Box to my tube pre-amp and noted the same outstanding attributes I discerned on my tube amp; tightening up the center image focus, more impactful bass, more nuanced texture, better soundstage separation/depth/layering, transparency/clarity...

Wig😁👍

Over the weekend, I also tried the copper and brass sluggos but prefer the copper in my system.

Wig 

So now I have tried both the copper and the brass slugs and I prefer the copper (with my equipment that the Fuse Box is used with).

ozzy

BTW, I just received the new short power cord to be used with the Fuse Box. Very nice, well made.

ozzy

steakster, verafiaudio

I have thought of that too! Bypassing the entire fuse/holder would be the ultimate since the Fuse Box would protect the component. It will be on my future hit list to try. Although, the Fuse Box slug is the most convenient way to accomplish this.

ozzy

@steakster 

The holder itself is a main part of the problem -

I've worked this comparison 

Just my 02 cents 

Thanks - Mark

Which statement is true:

If you can hear a difference, then there is a difference.

If you can't hear a difference, then there is no difference.

It’s very interesting that thus far that most of you prefer the brass over the copper slug.

So, I’m getting ready to try the brass one. But I wonder if it matters as to what piece of equipment it is used in.

My Mono block amps have 2 fuses in each. One that powers the main power supply (6A) and the other the input section (1.5A).

I have the "Fuse Box (6A)" powering the main power supply and I am still using a SR fuse in the other fuse input section on my amps.

ozzy

Good to hear the Fuse Boxes are performing as advertised in your systems 😁... Will be implementing another one for my tube Pre-Amp and it's hard to unhear what you have heard after removing the Fuse Box.

Wig

@ozzy I was also surprised that I prefer the brass.  Still trying to justify that to myself.

I've got my polishing cloth and bullfrog standing by for when I get the fuse boxes back, but I'm planning to run them a few days before I try anything else.

skucie,

Nice review. Interesting that you like the brass slug better. I still haven’t tried it yet, but I will.

I have also treated the copper fuse with Rick Shultz new "Pro" enhancer product that he kindly provided. His previous products were the NPS 1260, NPS Q45T.

First, I will try the brass au naturel.

ozzy

Mark was kind enough to send me 2 of the fuse boxes to try on my preamp and power amp.  I'll do my best to give my impressions, though I feel like the sound is still changing and improving.

Out of the box (copper sluggo):

Bass.  More in both quantity and definition.  I considered dialing my subwoofers back a few times in the first hours, but eventually decided it sounded 'right' with my original setting. 

I'm noticeably lower on my line stage's volume control.  Maybe 5 steps lower (out of 103 total).  I usually listen around 30 and am now listening in the mid 20s.

Instrument separation is better and the leading edges of notes are more clearly defined.

Soundstage depth is reduced slightly.  Soundstage width is unchanged but the outer edges of the stage are more illuminated. 

Complicated passages are congested.

Vocals and high frequencies sound a little etched and somewhat artificial like I'm trading some naturalness for additional detail.  

After a week (approx 25 hours):

Soundstage depth is back to where it was.  Improvements in width and illumination remain.

Congestion on complicated passages is no longer an issue.

The etched quality I noticed initially has settled down nicely and things are sounding natural again.

I like what I'm hearing.

Today:

I have lent the fuse boxes to a friend of mine for a couple of days to try on some other equipment.

Before I removed them from my system, I briefly tried the brass sluggo.  I think it is the better sounding choice for my system.  Tonality and texture on stringed instruments seems appreciably better.  High frequencies seem more natural and appropriately scaled.  I'm less confident in these observations because they were made in about a half hour but will follow up when I have had more time to compare.

Last night, I listened without the fuse boxes in my system.  It was a short session, not as engaging.  I'm looking forward to continued experimentation with the brass sluggos.

I'd also like to try polishing the sluggos and treating them with progold or bullfrog contact enhancer.

Sorry for not posting for a while, I have had many personal items of late that took me away from listening to music.

I have had the fuse box(s) connected to my amps for about a week, probably have played music with them in the system for a total of 10 hours.

What I can offer is that there is no downside, I am hearing a calmness that is pleasant, perhaps my amps are finally playing as to the way they were designed.

I have only tried the copper slug thus far, but I will try the brass.

BTW, I did make a short 12" jumper power cord to use with my units. I think Mark will soon be offering a similar power cord to be used instead of connecting another long power cord to the Fuse Box.

ozzy

@rc22 

Yes, the Fuse Box does come with a copper and brass sluggo's. 

The Fuse Box is not shipped with any power cords and using PC's I currently have on hand.

Wig

Thanks to the earlier adopters of this product for posting.

If anyone has a link to comprehensive product information, I’d love to have it. 

It sounds like the product comes with sluggo’s of brass and copper for the user to experiment with.  Is that correct?  

Wig, rareace….did you replace the stock powercord on the fusebox or are your positive reports based on the stock cord?
 

In my system, I prefer the copper sluggo as it’s closer to scale in terms of image size; if you thought your speakers were holographic, wait until you add a Fuse Box and your front wall becomes a "chameleon".

Will do more listening between the sluggos after more settling in time...

Wig

I received my Fuse Box and right out of the box it’s a nice improvement over the stock fuse. I also agree the Brass is the better sluggo and along with the Purons have added an impressive uptick in performance!

Guys,

A few weeks ago, I stumbled upon a product here on this forum called a Swiss Digital Fuse Box. I must say that after reading the description of the Fuse Box, I was intrigued! I immediately remembered back in the old days when a lot of guys were bypassing their fuses on their Magnepan with noticeable improvements.

I do own both Synergistic Research Black, Blue and Orange Fuses as well as Quantum Science Blue and Yellow Fuses and with the steady increase in fuse costs, the Swiss Digital Fuse Box from a cost basis and the potential of increased sound quality made sense to me.

I could not wait any longer and placed my order for 10A SB (Tube Amp) device and package was received within 3 days after ordering. I just had to experience this Fuse Box in my system to “Hear” what others were raving about…

It does not take long to discern the meaningful and impactful sound that the Fuse Box is allowing your component to extract delicate and nuanced sound without restriction; in my system, I discerned a very welcoming and noticeable increase spatial ambiance cues… These spatial cues extended the soundstage 2-3 feet outside the edges of my loudspeakers but the Fuse Box did even more tightening up the center image focus, more impactful bass, more nuanced texture, better soundstage separation/depth/layering. Transparency/clarity is quite remarkable as well and its crystal clear and warm at the same time.

The sound is smooth, yet dynamic with everything within the soundstage being laid out distinctly with precision!

The best way I can describe the sound is that you are immersed in a sound field with sound coming from all around you… I did notice better sound the next day and imagine the Fuse Box will improve with use and settling in time.

I can say without reservation that the Fuse Box slaughtered my SR and QSA Fuses and Highly recommend this product to those looking to remove their restrictive and expensive boutique fuses…

Wig 😁👍

I just installed the Fuse Boxes. I’m not sure if there is a break in period, but at this moment I am liking what I hear. There seems to be more dynamics and perhaps the music seems louder.
I mean when you think about it we are using perhaps 12-10 gauge wiring (including power cords etc.) and it is all passing through a small hair like wire (fuse) but by-passing that (fuse) stumbling block there should be more power available.

More to come.

@emailists

I apologize for not getting back here earlier

The main purpose is to PROTECH the amplifier within your question.

Protecting the Power Transformer is KEY – the B+ fuses that still remain (no slug inserted) will work fine doing their job @ 3amps. Nothing changes there

I do urge reading the manual which is on our home page verafiaudiollc.com

FUSE BOX is in several systems now. Had e-mails last night with very positive early results.

Thanks

Mark

Looking forward to your findings.  

Just received my 2 "Fuse Box" 6A units that I will use to power my mono block amps.

ozzy

Can you explain further how a 6 amp protection circuit can protect a part of the equipment rated for only 3 amps?  

Also I might suggest making some comparison recordings made with the Fuse box and without.   Positive Feedback did an article including links to WAV files (linked below) about a mastering facility trying out Niagara 5000 power conditioners.  They did two masterings of tracks - one using the power conditioning and one without.  The difference is astonishing, even listening via my small system in another location.  

If you could record the differences of the output of a preamp or DAC the way this article does, I feel it could be helpful to illustrate this new very interesting product category.  

PS - sgordon1 is using this product successfully - please connect with him 

We have shipped several manufacturers their first FUSE BOXES 

More about that shortly 

Thanks

@emailists

FUSE BOX will work fine with Amplifiers etc. with multiple values

We set FUSE BOX for your Power Transformer “value”.

How can you know what’s what – simple

Lets say your amp has 2 x 3amp fuse and 1 x 6 amp

SELECT THE LARGER SINGLE VALUE – in this case 6 amps

Mark

BTW – the complete Instruction Manual is now on our Home Page

www.verafiaudiollc.com

Please read it - Thanks

Quick note

We are now set up “digitally” with UPS for an even better International shipping experience

All digital – very quick and painless now

Thanks to all of you for your incredible support re Puron and FUSE BOX

I just got an email from a dealer selling these.  I have a question about if it will work with equipment that has more than one fuse.  Would love to read about someone trying this.

@skucie

Appreciate your note -

Programming is done via ICP – Lots of care went into the programming protocol(s) and it’s very foolproof in fact

The idea was that IF you wanted the FUSE BOX re-programmed we at the factory would do it for you for a nominal (like $25 dollars nominal) charge

Re trying it – please ring me up (phone number on the site) @ www.verafiaudio.com and I would be glad to send you a unit or two to try.

There’s no shortage of people here who think this is all a bucket of hooey – only it’s not.

We’ve had 11 units in the field for 6 + months and the unanimity of positive voice re FUSE BOX has been great.

Money where my mouth is – please get in touch.

Thanks

 

@steakster

Great Forum Name – lets start there.

I want to find the proper way to say this without sounding like a complete ass.

Over several companies and many OEM’s that I’ve built for I’d like to think that I’ve spent the last 16 + months thinking about how to best move forward with FUSE BOX

Daniel and Markus have as well. We feel this is the best way to “prove out” the concept and product efficacy. Your idea is quite good and maybe in the future that might work well – In fact, I can imagine it would

Lots and lots of testing through Alpha and Beta before the first production was run.

We’d like to drive the cost down – but until we get further down the road it won’t be easy.


@yoyoyaya

Thanks as well.

We are looking now at ways to certify. That said – Sluggo makes that difficult… but there are ways.

I know that FUSE BOX will impress. I also know it’s a hard sell to many that cannot imagine how this can improve the sound. Only it does (forgive me).

In days to come we will have the Instructions on the site. We will also post some tech data for those that like to understand what they hear to the measurements.  

@verafyaudio. Thank you Mark. I actually think the product makes sense. Is it or will it be CE marked?

@verafiaudio 

Thank you for your response.

Regarding the programming, is that done in production or can the end user alter the settings?  I'm trying to determine if it would be possible to try it on a few different pieces of equipment to see where it would have the most impact.

Thanks again.

@yoyoyaya

The guys that worked with me on this product are Swiss. It’s their name and I kinda like it

@68pete

Many thanks sir. Every day doing what I can to do “my part” – still having fun 😊

@skucie

Thanks for your question

It's Programmed – at this point we can only do up to 10 amps – later, we can do up to 15 amps.

Fast or Slow Blow

We can support 5 x 20mm and 1.25m x .25 inch fuses types

Ships with Brass Slug and Solid Copper Slug


All

After several messages yesterday and today – we are setting up the site to offer those interested our full Instruction Manual (with Warnings)

More to follow

How is the fuse value set on the SD fuse box?  Is it set from the factory or user-adjustable?

Does anyone know the maximum fuse rating?

If the Audio World has more dealers like Mark it would be a better place

PS It's not a fuse box as it's a circuit breaker not a fuse.

Given the dictionary definitions for fuse, perhaps just as well:))

What exactly is (a) Swiss about it?

Extremely silly.  The Swiss ought to know better; they still make good watches.
