FUSE BOX delivers perfect protection and superior sound

Encouraged by the improvement offered by the PURON plug-in filters, I spent some additional time reading 


I wondered if a second product, unrelated to PURON, can also raise the bar for recorded music?  FUSE BOX is a system that replaces a fuse in a piece of electronics.  A metal SLUGGO (insert either the brass or copper option) goes in the fuse holder.  The power cord you have been using goes into one end of the slim, lightweight BOX.  From the other end of the BOX, another power cord (quality counts!) leads to your power conditioner or to the wall.  Simply plug and play.

Each FUSE BOX is calibrated according to the traditional fuse it will be replacing.  By providing the amp value, fuse size, and slow/fast blow, a unit can be tailored to your specs.

I took the plunge by requesting a FUSE BOX to fit into two different systems.  I use a Black Ice FOZ SS-X Sound Expander in both a headphone (Synergistic blue) and main system (Synergistic orange).  This wonderful piece is in the middle of both systems, between the cd player and the amplifier.

Starting first in the smaller system, there was a break-in period of about 30 hours before the sound really took off.  A huge positive step (for me) was then replacing the copper sluggo with the brass version.  Now I heard the depth and warmth, in addition to the detail of the copper version.  The traditional Grado sound through the over the ear headphones (Prestige 125 model) was rich, detailed, and balanced.

I spend much more time listening through full range Martin Logan Expression ESL 13a speakers.  I recently added two PURONS to this system, plugged into a Synergistic Research Powercell 12 conditioner.  Even when (intellectually) I believed this combination had already taken me to the "top of the mountain," I was happy to be proven wrong.  With the brass sluggo in the SS-X, the "you are at the recording event" is very powerful, and in a way I had never heard before.  It's like I have the best seat in the house, for every recording.

For me, FUSE BOX offers the protection of traditional fuses, without fearing they may need to be replaced (since FUSE BOX can be easily reset).  With the two sluggos provided, the sound can be adjusted to one's preference.  And I still have the flexibility to change this arrangement in the future, as the sluggo is never permanently fixed to the fuse holder.

A big thanks to Mark Schifter at Vera-Fi Audio, for patiently helping me.  With a 30 day return policy, my guess is that many music lovers will be asking Mark to program a unit, so they can evaluate it in their systems.

My answer, to "how can the sound possibly get any better?" is FUSE BOX.  Highly recommended.



@whostolethebatmobile , understood, granted, and thanks for your insight. *S*

But I still have a healthy cynical curiousity about small sealed boxes and the gremlins within....

And the belief that a fuse shouldn't do anything other than serve and protect, with zero effects. Therein lies the discussions and the advent of major money fuses.

When a fuse has a tiny whisker of wire being fed by 12ga. and lower, or exotic cables is a reasonable consideration.  Which is why the concept of a active circut breaker monitoring the inputs is an outstanding idea, and mho worth wondering over....

...but I'm just a weird troll, gargling in the fringes... ;)

Geeez, so if a small child or animal bumps the power cord, I live 120V brass sluggo is exposed on the floor???


I said: Fuses are are inherently good for audio equipment.

Fuses can protect the internals of audio equipment from damage. Have a good day. 


I was altered to your note and yes of course – one in the same

I’ve worked very hard over the last 12 + years to pay back and pay forward both with good works.

I have run Product Development for Underwood (Core Power Tech, LSA, and Emerald Physics) and the work product etc. over these 12 years can speak for itself. Doing tjne same for the new Bob Carver Corp. Hearing it from me will have little meaning – except to say at 66 it’s still the “core driver” of my life daily.

The product being spoken about here is the Swiss Digital FUSE BOX and in my (albeit biased) opinion it IS a real step up. The product is Science Driven – it works well and those that have tested and bought seem to really like it. Thanks to @sgordon1 for stepping up to get it said.

Like Puron in another area – doing what I like and enjoy doing with fine products and a long 54 year history sadly littered by a big mistake driven by greed and avarice (with a big dollop of stupidity).


Here to do better –
