The secret to a great amplifier...


Is a $150 Orange fuse from Synergistic Research. Seriously, extreme boost in sonic performance. Blacker background, larger soundstage... if I wanted to make some bucks, I’d put these is cheap OEM compnents and start letting the accolades and purchasers come calling.

Mind you, I have a high value-oriented $20k system, so it was nice before, but damn!

This is Paul, who is no stranger to hyperbole, sort of like your description.

- A single change was made. The unit was turned off, said change was made, then turned back on.  There was no repeated testing.

- Paul say's marvellous improvement

He is already preconditioned for their to be a change. The expectation is already set.  This is what audiophiles do to themselves all the time. A real test would be changing the fuse between two different ones, and sometimes not changing at all.  It is not a subtle difference.

Of note, power cords likely taken on / off wiping contacts, case top removed to change the fuse (was it left off) ... oh, and Paul knew he took the case top off, so further expectation bias.


As noted above, I am all for people testing fuses, just test them, with only your ears, and not your eyes. Get someone to help you so you can eliminate bias. Then maybe we can put this topic to bed.
By the by, there's a video on YouTube by Paul McGowen where he talks about fuses and it meets your very same requirements. In it, he tells of a friend of his who's doing something to one of his amps away from Paul, who's sitting some distance away, both talking audio.

Now Paul has no idea what his friend is doing, who tells him to just sit there and listen. Paul never knows if something is being changed or not, when prompted, or what it is that's being changed. Every single time he's asked if he hears a difference for better or worse, he's correct in his assessment. 

Turns out his friend was swapping out a fuse.

All the best,
Nonoise

"If you can’t measure......"     That’s been, "science’s" failing, throughout it’s history and- always my point.     ie: Knowing how or what to measure.     If you had the slightest background (or- genuine interest) in the subject, you’d understand.     With no foundation/higher education in Physics  (obviously), you can’t begin to grasp anything (the, "possibilities") to which I refer.    Hence; your posts are full of uneducated, "leaps" (assumptions) and any responses (on my part) are a waste of keystrokes.


You can throw all the insults you want out. I will put my knowledge and understanding of physics, experimental and theoretical up against yours any day. Have at it.  You show your hand when you talk in flowery language, but can't apply specific aspects of physics to very specific problems. That is the difference between people who know, and those that just read. Those that know talk in specifics, not generalities.

But, most of all, you continue to try to convince others not to use proper experimentation in perceptive analysis. No person in the sciences would ever claim that none blind tests were valid or continually promote them as having significant validity.

As noted above, I am all for people testing fuses, just test them, with only your ears, and not your eyes.  Get someone to help you so you can eliminate bias.  Then maybe we can put this topic to bed.


Anyone interested in whether installing a better fuse (whether high-Dollar, "audiophile", or- simply a better constructed one, as mentioned by some), can make a difference in your system’s presentation: just TRY them, for yourselves, as did this thread’s OP.      The Naysayer Church HATES it, when THAT happens!            Whatever the rationale; if it sounds better TO YOU, it will have been worth the effort.               
"If you can’t measure......"      That’s been, "science’s" failing, throughout it’s history and- always my point.      ie: Knowing how or what to measure.      If you had the slightest background (or- genuine interest) in the subject, you’d understand.      With no foundation/higher education in Physics  (obviously), you can’t begin to grasp anything (the, "possibilities") to which I refer.     Hence; your posts are full of uneducated, "leaps" (assumptions) and any responses (on my part) are a waste of keystrokes.
And again,  you are just making things up using terms you don't understand very well, while eschewing the one form of science that would deliver a proper and somewhat repeatable result, proper testing, with our ears, and not our eyes.

No, you are of the opinion pleasing ones eyes, which can fool the brain (for a period of time) that the ears are happy, but the ears are not actually happy, a higher level decision was made to say "we are happy". However, as it was not a real change, it does not last.  It is like a pretty car with bad handling. You come out and look at the car and go, "oh its so pretty", and you forget about the bad handling ... till you are 20 minutes into the drive.

"A modicum of Wave-Particle Duality and QED study, can open one's eyes to the POSSIBLITIES, surrounding what's happening with conductors, dielectrics, and our voltages/signals." - This is just subterfuge and completely meaningless. We can measure bulk effects with great accuracy. You don't have to understand everything that happens at a low level to understand the macro effects. If there is no "why" then the how is quite meaningless.  Bringing up particle/wave duality and quantum mechanics to try justifying that a fuse may be important is called clutching at straws. If you can't measure a sufficient bulk effect, than the underlying physics does not matter.

I will make a leap and guess that you don't even really understand how a fuse behaves at a bulk level in a power supply circuit, yet you want to start talking low level physics?
"You can't claim to be a person of science on one hand, then conveniently reject the science that does not agree with what you want to believe (and accuse other people of Dunning Kruger)."         As I stated earlier;   "A modicum of Wave-Particle Duality and QED study, can open one's eyes to the POSSIBLITIES, surrounding what's happening with conductors, dielectrics, and our voltages/signals."     None of it (modern Physics) supports AC pushing electrons through a wire.      Of course; that's was what being taught as, "Science" (regarding electricity) by the Engineering Dept, while the Physics Dept was teaching voltage/signal wave propagation, at Case.     That was the Sixties.    QED was still young and related in lectures.        No one that can prove via, "Science" that changing a fuse can't make a audible difference, or: vice versa.        All anyone has, at present, is Electrical THEORY.       Again; theories don't prove anything, but: I choose to put my confidence in the latest (I like to keep up).           I'm not on this forum, to impress or convince anyone, of anything, by winning some kind of educational or semantic, Urinational Olympics.      Only: to encourage those, so disposed as to experiment for themselves and confident in their systems and faculties (their own minds, GASP), to do so.        That the variables are manifold should be obvious, to most anyone.      As should: the propensity of some, to constantly change subjects.       I'm of the opinion: pleasing one's own ears, is ALL that matters.
and trust your own senses

That is the same argument that people who believe the earth is flat use.

What is amazing is with all the evidence showing how easy it is to fool our senses, that people still insist they are special, and that quoting the internet somehow makes them an expert.


We know without a shred of doubt that visual stimulus can impact our audible perception, and our taste perception even our emotional perception. Why insist this is not true. You can't claim to be a person of science on one hand, then conveniently reject the science that does not agree with what you want to believe (and accuse other people of Dunning Kruger).


First red (or was that black), then black, then blue, then orange, and all age somehow "so much better" than the one before. It begs the question, was your system so awful to start that successive generations of fuse upgrades made a huge difference? Call me skeptical.


I wonder why these fuses blow more often than other fuses?
jaybe665 posts10-09-2019 7:43amI find SR fuses to blow much more easily than a normal fuse with the same rating. After this happening a few times with the Blues I took the advise of Alfred at High End Electronics and bought a slightly higher rating fuse but it too eventually blew. Two pieces of highly regarded equipment this happened with that otherwise have no problems.

Far as, "a proper experiment", as I said, "IF you’re interested in improving your system’s presentation, have a shred of confidence in your capacity for perceiving reality and trust your own senses: try a better fuse, FOR YOURSELF."         
   "........knowing more about what happens at the atomic level does not change what happens at the macro level."          BUT; new knowledge will, generally, help us understand the WHY (at least: get us closer).      A modicum of Wave-Particle Duality and QED study, can open one's eyes to the possibilities, surrounding what's happening with conductors, dielectrics, and our voltages/signals.          Of course; arguments between theories and concepts will never end.     The only thing that should matter here, is what one hears for themselves, in their own home.      
A lot of our current theory of electricity is actually based on things we didn’t know in the 1800’s, however, knowing more about what happens at the atomic level does not change what happens at the macro level.

I agree, everyone should try fuses, and when you do it, do a proper experiment and have someone else change the fuse (or not) and yes, absolutely trust your ears to determine the result. Highly encourage that!

The Naysayer Church wants you to trust their antiquated science (1800’s electrical theory) and faith-based, religious doctrine, BLINDLY ("Trust ME!", their credo).

Now, given that some of those fuses are $100+, how do you propose validating the fuse rating when it appears the supplier has not?

Anyone that knows anything about the sciences, realizes that something like 96% of what makes up this universe, remains a mystery.

Why is it that those least knowledgeable about the sciences are most apt to support things that are not supported by science?
Again:     No one can possibly know whether fuses will make a difference, in their system and room, with their media and to their ears, without trying them for themselves.      Some companies offer a 30 Day Satisfaction Guarantee, so- those that are actually interested, have absolutely nothing to lose.     Anyone that knows anything about the sciences, realizes that something like 96% of what makes up this universe, remains a mystery.       For centuries; humanity’s seen, heard, felt and otherwise witnessed phenomena, that none of the best minds could explain, UNTIL they developed a science or measurement, that could explain it.     The Naysayer Church wants you to trust their antiquated science (1800’s electrical theory) and faith-based, religious doctrine, BLINDLY ("Trust ME!", their credo).    Theories have never proven or disproven anything.     It’s testing and experimentation that proves or disproves theories.       IF you’re interested in improving your system’s presentation, have a shred of confidence in your capacity for perceiving reality and trust your own senses: try a better fuse, FOR YOURSELF.           The Naysayer Church HATES it, when THAT happens!

Based on all the report of these magical orange fuses blowing, I wonder whose fuse would blow first :-)

I hope they are not taking a low value fuse and marking it as a higher value. That would be one way to reduce the noise in the power supply.

     I was wondering if anyone has bought hundreds of dollars worth of these magical orange fuses, noticed no performance improvements  and blew their own fuse?

After doing some research I found Littlefuse sells AUDIO/MEDICAL quality fuses Series 285
they are all slo-blow, buy come in various sizes including 5x20

The 218 series ceramic are fast-blow fuses, but not the audio grade.  Still an improvement over glass fuses.

Did a/b and there were an improvement in my amp, and preamp. I personally prefer a known engineered part with industry / manufacturing standards then taking a chance with any audiophile fuses that do not have any standards.

I am not saying all audiophile fuses have no standards. So use caution.



https://m.littelfuse.com/~/media/electronics/datasheets/fuses/littelfuse_fuse_285_datasheet.pdf.pdf
Yes they improve the system.  Keep in mind fuses are also used inline for speaker/amp connects (no power only).  For those who are more budget minded the litlefuse 285 slow blow and 218 fast-blow are great options under $10 each. 
The fuse that was called for always blew when volume was increased

You never heard it at the level you wanted.
Music always sound better when you want to hear it at the volume level you want, sound quality had nothing to do with the fuse, you were just enjoying it more, because it was finally louder.

Cheers George
A very long time ago a friend of mine had a Pioneer car unit in a boat . The fuse that was called for always blew when volume was increased so when it blew one time all I had was a much larger fuse and we used that and all of a sudden the sound was greatly improved. I don't know if some of these Hot Rod fuses are better but in that case being able to pass more current did in fact improve the sound greatly so it sure wouldn't hurt to experiment
So were these Orange fuses inserted in the power amplifier outputs to the loudspeaker or in the AC Mains line to the unit?  Either I missed it or that installation point was never made.
Right.  High-end boutique brands never rebadge cheap stuff from China.

(Just to be sure, before buying that next power cord, go a quick visual search of Amazon and AliExpress.  You might be surprised.)
Quarks are in the signal path ! Spent the week trying to tame them :-)

speaking of “ lists “, @tubebuffer is on my must read list !! Witty, subtle savage with a spouse who dresses well. 
Thankfully we are down to just a few psychotic malcontents.

Then we can move along to the next thing they don’t understand and all will have to deal with the flufferstorm of their incapacitates, again.

To the chagrin of all involved. Like clockwork. Expect it like the Spanish inquisition.

I would prefer to disarm and wind down the confrontation but it seemingly can't be. So we're left with the hard burn from the soldering iron of truth. Burn baby burn. And if they find some smarts in the interim, then maybe they can get out of the chair of their own making.. and finally run away. And never sit down in those sort of chairs of ignorance and projection, again. We can hope, we can dream....

     You guys n gals think Synergistics charging $150 for a fuse is bad.  How about their new product, Mouse Milk at $500/ounce?
     Their ad literature claims: "This liquid gold is gently coaxed from our pure-bred, corn fed, non-smoking, post-natal and virgin herd of mice by our extensively trained team of audiophile rodent wet nurses that have been preselected for their gentle, nimble and abnormally tiny hands." They also state the milk contains "non-placebo effect properties".

    Sounds too good to be true, right? Post-natal virgin mice?  Audiophile rodent wet nurses with tiny and nimble hands? Those have all gotta be hard to find, right?  Perhaps this explains the high price?
    In any case, I just ordered 2 quarts, I'll report back.

Synergistic Research has been known to rebadge and decorate cheap Chinese junk FYI. The ultimate purveyor of snake oil products. 

Yeah mate I just love it up the **** from fusers, they turn me on.

Fusers have no idea, there’s many things that are worse in series in the ac line than a fuse, they are just being suck into paying $150+ for a what is a 50cent fuse by these snake oil fuse con men. 


stevizzy Just put one in my vacuum cleaner sucks much better.
I just tried one up my **** now I can play tunes when I ****

Cheers George
Just put one in my cable box and vacuum cleaner. Picture on TV looked great but WOW the vacuum cleaner sucks much better.

OK, let’s all at least put this thread out of its misery and move on. Definitely not fun anymore...
Strange to say, coming from one that claims this below is the sound difference when he inserted a snake oil fuse.

"The secret to a great amplifier...is a $150 Orange fuse from Synergistic Research. Seriously, extreme boost in sonic performance. Blacker background, larger soundstage..."


It's like having thick cables for your plug in and exotic wires for interconnects! Look inside your Amp or Pre-Amp and see the size and quality of the wire! You might re-think your thousand dollar purchase for Bling connectors! I have had both!Cheers!

... start smoking pot or ingest some edibles. It's legal in most states now and works wonders on my system.
Are you talking about the US? Pot is legal in just 15 states.
If you want your system to sound better, start smoking pot or ingest some edibles.  It's legal in most states now and works wonders on my system.
I would say these days, fuses in the output of amplifiers are not overly common. Some amps have them, but these are now the exception, not the rule.
mcintosh ma12000:
  • Our fuse-less short-circuit protection circuit Sentry Monitor™ that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normal

It seems that some in this forum are scouring the posts with relish, trying to pick apart an offending word or comma so that they may spew their venom.
Tim, nice reasonable post.
If I come home in the evening and sit down to listen to my system the sound can be a little different, even though, I didn't do anything to it. There may be some reason for it in the vast sea of space. But likely I don't worry to much about that, I just use my own judgement if it's good or not. It has got me this far, and I have a great sound.
So it seems reasonable to me a little fuse can change things more than seemingly nothing. So I have tried a few and am glad I have.  Just my way of going about it, as Cleeds implied above.

     I consider myself a mostly reasonable monkey, who respects scientific knowledge and the empirical process utilized to validate and accumulate it.
     I realize I prefer to keep an open mind and understand that I tend to gain knowledge about this hobby and my personal system preferences best through personal experimentation and experience. But I’m also not totally immune from trying, and even adopting, audio lore, marketing, tweaks and perhaps even a bottle or 2 of snake oil.   Do a pair of maple isolation amp platforms with brass cone-spiked footers and a pair of Mye stands count?  
     In other words, I generally like to try new, different and various products and methods in my own room and a/v system and then just call things as I see and hear them. In retrospect, I think this approach has worked out well for me over the past 40+ years and it reinforces my belief that this hobby, based on my personal experience, is best described as an audio and video journey.
     Sometimes you’re convinced you have the answers and reached the blissful end to your a/v journey, only to discover there’s more to learn and discover. I think I’ve reached my blissful destination, but I’m not sure and don’t really care since I’ve enjoyed and continue to enjoy the journey so much, that I hope it never ends.

Enjoy,
Tim
If someone gave me one, being a reasonable person, I would try it.  But I will not buy a $150 fuse.  That's too nutty even for me.

When you know science and reason has lost the war is when you have people claiming that those who want to see evidence to support observation is considered on par with Qanon nuts ...
Why would someone seeking scientific evidence come to a hobbyist's site with their demands? It doesn't make sense, unless the goal is simply to argue and disrupt. No one here owes scientific proof of anything to anyone. If you seek absolute proof, you're simply in the wrong place.
