Audiophile fuses - Synergistic Black fuses vs the còmpetition

Between friends samples and onew I havd bought I find that these Synergistic fuses to be the best balanced. And without question inner detail .I originally had Hifi tunING supreme.which are good  but not in the SR class 
The Audio horizon I found more tipped up compared in certain areas furutech were no where's as detailed . The SR  Black fuses use the latest in Graphene  technology everyone from Nasa 
To the latest hi tech 3d printing and many 1,000s denser then Copper.Silver or Platinum.
All super computers are now using and soon home computers it is much faster and accurate.
But also smoother and more organic sounding parts connecxion if you purchase at least 3 or more 
May give you a respectable discount. Email Chris the owner at Tech go to the site . Lucky I only had 5 in my system. One thjng that was surprising is that I put one in my JL audio  Subwoofer  thd bass was noticeably more accurate and articulate.  2 thjngs to mention .these fuses take up to 200 hours to fully runin.but after 100 hrs 90% of the runin  is complete, also  Always go up to the next size ,for standard cheap steel fuses can vary up to 15%,where these fuses are typically within 
1%.  I found that no fuses popped .on a Modwright pre I popped 2 , then went from 2 to 2.5A
No problems and Make sure you get proper  slow-timed ,or Fast blow. A No Brainer like a very good cable upgrade and comes with a 30 day money back guarantee. 
That's funny. 
Oh no, not again.

Actually the HiFi Tuning Supremes aren’t the real competition.

What's the NASA connection for Graphene? Are there audiophiles secreted away within NASA somewhere? Are astronauts audiophiles?
No brainer Explains it. Just do it slogan taken.
gk how  would you know?  I thought no fuses used in your system I mean Walkman.  Too many issues there for you that Walkman solves completely for the price of a fancy fuse?

I see everything, mopman

Me too. 
I see said the blind man as he picked up his hammer and saw.
Where is your data that shows this "1%" variance? Seems odd that these audiophile fuses require you to go up a size just so they won’t blow (even odder still when they are touted as 1% tolerance!).

Those "standard cheap steel" fuses do not exist as fuse elements are not steel. Besides, take a look at the data sheets of Littelfuse, for example, and tell me where I can find the same for the boutique brands. Also, if standard fuses have a 15% out of tolerance, then how can Littelfuse make fuses with 4 ratings between 1 and 1.5 amps? (1.00, 1.20, 1.25, 1.50).

I’ll never argue about what you do or do not hear, but don’t throw the technical stuff at me as justification. Going up a fuse size because you want to save your $100 fuse investment puts at risk your many times more expensive equipment. What is protecting what?
That might be fake news previously known as made up stuff. 

As usual a lot of ignorant statements .a lot of critics with nothing  to
say but negatives .unless you have personally  put these fuses in your system
and give them at least 100 hours then don't comment  for you are speaking out of ignorance .and with some I have found the fuses are to pricy for their $500 
receivers .and a lot of exotic metals first get their start through high tech agencies like military or NASA to answer some of the skeptics.
if you took the time and looked up metal index on resistance copper or silver  has 
7 times less resistance then the cheap steel fuses ,resistance is a bottleneck 
that is why each fuse  makes the system that much better.
Gs asked about data to support the claim? Nothing ignorant there. Why are you attacking people over a fuse?

also I have a sr red fuse in my preamp.   
"Why are you attacking people over a fuse?"


You post as if you are not intimately familiar with the viscous personal attacks by ptss and georgelofi on the other SR fuse thread while you stood on the periphery prodding them along.

I knew that this thread was ill advised from the beginning (second post) and now audioman is finding out why.

Wait a minute, a fuse is SUPPOSED to be a resistor, that's how it functions. And where in the world did anyone get the fantastic impression that the audio signal propogated through the fuse? If you want to hear a difference/improvement call it what you will, BY GOLLY YOU WILL HEAR IT!
Heck, I don't know Steve. You have a system where you can hear the differences. Why not try them and see for yourself?



"Wait a minute, a fuse is SUPPOSED to be a resistor, that’s how it functions."

Really? Then how come the whole goal of high end fuses like SR and HiFi Tuning and Audio Magic, etc. is to increase the CONDUCTIVITY of their fuses by using pure metals and cryogenic treatment. Thus, LESS resistance will be measured across aftermarket fuses compared to stock fuses. Electrical CONDUCTIVITY is the reciprocal of electrical RESISTIVITY, Hel-loo!

"And where in the world did anyone get the fantastic impression that the audio signal propogated (sic) through the fuse?"

Well, for one thing from the fact speaker fuses are mounted right where the audio signal enters the speaker. My Fultons had one fuse per section.

"If you want to hear a difference/improvement call it what you will, BY GOLLY YOU WILL HEAR IT!"

Most likely for fuse skeptics the rule is, "If you are psyched out by fuses or aren’t sure what to listen for or believe fuses are a scam BY GOLLY YOU WONT HEAR IT!
Your right. It's a no brainer just like a cable upgrade. 
Dkcockrum. Those were in self defense perhaps which is different. Some people make a habit of attacking people When challenged on an issue and bully tactics cannot be tolerated ever.   It’s an epidemic in this country these days it seems.
"Those were in self defense perhaps which is different."


audioman probably felt the same way above following your post: "That might be fake news previously known as made up stuff."

If you are speaking only for your reactions in the other thread, then fair enough. In no way can this be attributed to the others. They inserted themselves into that thread with the sole intent of ridicule and mayhem.

If folks stop posting here about their positive experiences due to fear of personal attack, this forum will serve little purpose IMO.

well in my defense I did not attack the poster rather challenged what was asserted which was not personal opinion all are entitled to but specific metrics cited. There is a lot of made up stuff presented as fact that goes around confusing people. Some seem to make a career of it with no remorse. Its important to challenge questionable assertions.  
Also audio mans response was to call the critics ignorant rather than present info to defend his assertion about the fuse tolerance. Wrong! He should be taken to task accordingly as well for that. 
FWIW I have never seen a +/- tolerance specified by any manufacturer of any fuse for either current rating or melting point. What is generally specified by Littelfuse and Eaton/Cooper-Bussman for their fuses, in addition to the nominal current rating, nominal melting point, and various other specs, are the minimum and maximum opening times for various percent overloads relative to rated current. For example, the minimum and maximum possible opening times when the current being conducted is 200% or 400% or various other percentages of the current rating of the fuse. Those tolerances (the differences between min and max) are usually fairly wide. I have never seen that kind of specification for any audiophile-oriented fuses, however.

You know, I’m game for an experiment and I just moved and am setting up the new listening room, so, when the dust settles I think I will try a couple of these and report back. Look I do know cables make a difference and tubes do too so, what the heck, I’ll give it the old college try. There, is that fair? After all, it’s only wire.
Looking forward to that Steve, whichever way it turns out.

I mentioned earlier that the Black fuse sounded slightly more natural than the stock fuse. Trouble is that it failed after about two weeks. Must have been an incorrectly labeled fuse because defective fuses are very rare. I'll ask Synergistic about this and try to get a replacement.
Also, this fuse does not have the values imprinted on the end caps, like most fuses have.
Maybe tear off the black label and see if it's marked there ?
FWIW, I tried 2 SR fuses on my Aurender. I wanted them to be better but there was no increase in SQ to my ears so I returned them. 

FWIW, I tried 2 SR fuses on my Aurender. I wanted them to be better but there was no increase in SQ to my ears so I returned them.

If there was no difference in SQ most likely you inserted the SR fuses in the wrong direction and the previous fuses were also in the wrong direction. Another possibility is that there's a mistake somewhere in your system that prevents fuse differences from being heard.
Post removed 
Huh... So just because I didn't hear a difference, there had to be a mistake with MY system? I'm not new at this hobby and that's a pretty arrogant assumption. 
FYI, I tried many different orientations with the fuses and Aurender, for the most part agreed with my findings. Maybe I should've told em they put the fuses in the wrong direction. 
Hey, I was just guessing. Why do you think you didn’t hear the fuses? Remember the context of all of this is that not only has almost everyone else who has tried the fuses heard them big time. Follow?

I'm  hoping to meet  "ptss" in person one day so that I can thank him face to face for the "kindness" he showed toward me in the other SR fuse thread.

Mapman ...

I thought you fell off the face of the earth. Nice to see that all is well and that you are using the Red fuse in your preamp. 

Whoa! Huh! Hey, was there a Mapman sighting? 

Here is a simple explanation , just look up resistance index in metals .
Silver vs the buzz fuse steel zinc.
The top fuses have ceramic instead of glass far lower micro vibration 
End caps are solid silver .Better then  7x less resistance then Steel.  Meaning 
Resistance  of this amount us a Huge bottle neck creating low level distortions 
With top fuses after about a 75-100 hour runin you get full benefits.
Better separation if instruments, tighter imaging, and better low lever detail.
Think of a 1 inch pipe vs a 1/8th inch pipe .the electrons flow much more at ease 
And these are the results. One thing to mention. The rest of your system needs 
To be addressed quality Audiophile power cords ,interconnects, and dpeaker cables, not monster Cable or blue jeans those are basic  cables.
Engineers are the very worst .I cannot tell you how many say a power cord is a power cord, or capacitors or resistors all dound the same ,breakin is in your mind.
I have spent years molding and listenjng and documenting changes well over 15,000 hours literally. Owning a aufio store until 06 I had plenty of time and having a technician a lot of upgrades . Keep an open mind One more thing the Best 
For your contacts and last for years is Stabilant-22  .I have tried them all 
$55 a bottle .clean everyyhjng including power cords first with high purity Alcohol.
Everyyhjng that has metal clean it ,and coat all surfaces Thin coat. Fuse holder
