I installed a SR RED Quantum fuse in my ARC REF-3 preamp a few days ago, replacing an older high end fuse. Uhh ... for a hundred bucks, this little baby is well worth the cost. There was an immediate improvement upon installation, but now that its broken in (yes, no kidding), its quite remarkable. A tightening of the focus, a more solid image, and most important of all for my tastes, a deeper appreciation for the organic sound of the instruments. Damn! ... cellos sound great! Much improved attack on pianos. More humanistic on vocals. Bowed bass goes down forever. Next move? .... I'm doing the entire system with these fuses. One at a time though just to gauge the improvement in each piece of equipment. The REF-75se comes next. I'll report the results as the progression takes place. Stay tuned ...
Any comments from anyone else who has tried these fuses?
but has anyone asked why not ALL manufacturers use these fuses in their components if they make their units sound better? If it were me, I would definitely signed a volume purchase contract with SR just to get some advantage over my competition. Sounds stupid?

If they did, when all this b/s voodoo is finally realized, then they’d be tared with the same brush, and never ever be trusted again.
But SR has never stated in posts or writing themselves, that "these fuses will make your audio sound better", they’ve left it up to the audiophiles gullible "expectation bias" to sell them and keep the BS voodoo sales alive.
BTW Have you noticed that the directionality talk of these fuses has dropped totally,"the signs they are a changin" Dylan. Cheers George
oregonpapa is smokin some more of his "special blend"--probably the most valuable component in his listening arsenal. And the poster trying to say 2 manufacturers recommended these junk fuses has backed off promptly when asked for clarification. Again, it's shameful that some unconscionable types, charlatans,snake oil salesman continue pushing bull shite
^^^ Let's say it costs $2500 to manfacture an amp. The factory sells it to the dealer for $5000. The dealer then sells it at retail for $10,000.
If you were the manufacturer, you would have to double the price of the fuse to the dealer and, the dealer in turn, would have to double the price of the fuse when selling the piece of equipment to the end consumer.
Now then, in the case of the high end fuse: The factory buys the fuse for $50.00 ... 50% of retail. The factory increases the price to the dealer by $100. The dealer then turns around an sells the piece of equipment marked up by another $200 to cover the new fuse.
As an end consumer, I would rather pay retail of $100 for the after market fuse than pay $200 for it placed in my new piece of equipment for me at the factory.
64 pages... this must be a record...I (obviously) haven't read every single post on every single page, but has anyone asked why not ALL manufacturers use these fuses in their components if they make their units sound better? If it were me, I would definitely signed a volume purchase contract with SR just to get some advantage over my competition. Sounds stupid?
Neither Decware or PS Audio endorsed any one brand ( actually PS Audio did mention a specific brand in their literature but I don't remember which one) but advocate trying differant brands to obtain the sound you like best. Paul McGowan wrote an article specifically about fuses and how they effect sound quality. I don't have the necessary knowledge to know if or why they work, but I'm willing to put my faith with the many here that love them and more importantly the men who designed my equipment endorsing their use.
My intention wasn't to belittle ptss's response, my response was in jest. My apologies if it came across negatively. I agree that fuses are put in a device only for safety reasons. Pauls article mentions how when designing one of their amps the prototype didn't have a fuse and when one was added for production the sound quality diminished to the point they had to make some design changes to get the prototype sound quality with the fuse. I checked with both manufacturers about fuse values and both said moving up one value wasn't a problem but going higher than the 1 amp for the Perfectwaves wasn't necessary, so I didn't higher values for them.
Just curious, did Decware and PS Audio simply recommend the Synergistic brand in general, or did they specifically suggest you use a larger value fuse than originally chosen for the gear?
That's how I read ptss's post. The ONLY reason to have a fuse in a piece of electrical equipment in the first place is for safety -- to protect the equipment from more damage than necessary if a component fails, and also for the safety of users. Fire and shock hazards are always a risk if the wrong component in an electrical device fails.
ptss......I appreciate your concern but I would think if there was any danger of the fuses damaging the equipment neither Steve Deckert of Decware nor Paul McGowan of PS Audio would recommend them in their products. Maybe it's an elaborate scheme on their part to get me to destroy my equipment so they can sell me more? ;)
Dear mac. How nice the company says it replace your blown fuse. And why shouldn't they? The profit margin is so "out of this world" that if they provide 1/2 dozen they're still basking in profit Far more important - who's going to bear the expense of repairing your precious equipment if the fuse fails to late?? If production is sloppy enough to blow to early; my friend Reason says it's sloppy enough to blow to late. Where I'm from, when we see a grown man doing something foolish, we don't wish them good luck; instead simply,wise up.
First off I must admit to being cynical about audiophile fuses but since both my amp and digital source manufacturers ( Decware and PS Audio) advocate the use of them I've taken the leap of faith and ordered Synergistic Research Black fuses for my amp, DAC and transport. I went one value higher for the amp ( 6.3 instead of 5) but stayed with 1 amp for the digital sources. The Cable Company said they would replace any blown fuses within 30 days so I should be safe. Hopefully I'll be as happy as so many here have been.
Synergistic Research or Audio Magic power cords and conditioners are next, does this craziness ever end? ;)
Kedoades, you can obtain Elliott’s recommendation at Synergistic Research. I had to move from a 5 to an 8 amp slo-blo fuse due to the immense size of my custom amp’s capacitors. He recommended the same as rated size fast blow fuses for my solid state 1978 Yamaha receiver and ADS speakers (for the tweeters). He also recommended a 4 amp instead of 3 amp standard slo-blo fuse for my Dynaco Stereo 70 (modified) which is a tube amp. So, it is equipment dependent as to using the same size versus larger size fuse. The fuses on both amps changed the sound 100% for the better-superb after 150 hours of use.
Yes, the trolls are out tonight. I don't care for the definitive reason(s) for the SR fuses *and duplex outlets) making my amps creating sound in my listening rooms that are so superlative versus just very good, everyone who has heard the result can testify that they never heard a better sounding audio system. I don't have SOTA equipment, but it's high end gear, wiring and tweaks (all my stillpoints, hallographs and isolation transformer).
Why are these trolls so interested in our (high end) fuse users welfare?
You might learn how to spell LITTELFUSE correctly when trying to make your point.
Is that all you have Geoff? beside the voodoo you preach?
Hopefully anyone reading this thread looking for serious information realizes the Synergistic Fuse = nonsense . Schills,charatans and 'snake oil' purveyors seem to delight,sadly, in bull shite.

Your complaint might have a little more authority if you spell LITTELFUSE correctly.
"BTW if someone puts these in as their + and - DC rail fuses, and one blows before the other, you can say goodbye to that amp if not the speakers as well." If you say so. But I suspect the operative phrase in that statement is "if someone puts these in...."
Ok I'll rephrase it just for you geoffkait
"BTW should some poor sod put these in as their + and - DC rail fuses, and one blows before the other, you can say goodbye to that amp if not the speakers as well."
"geoffkait Seeing it’s now fact by many having these SR mains fuses blow, that the melting point (which is the blow point) is wrongly overrated."
Huh? What’s a fact? "Many" is a relative word. How many? But more importantly, what’s the percentage that blow? How could you posiibly calculate it? We also know the stock non-audiophile fuses blow, too, you know, the Buss fuses and Littelfuses. So, what’s the difference? If things were as bad as you claim how are the aftermarket fuses companies still in business?

Oh, brother! Nice try, but that actually doesn’t make sense, that they sound better because they run hotter. What does their temperature have to do with the price of spinach? Why wouldn’t fuses running much hotter actually make the sound worse?

How about if I put it in the audio book of funny things people say?

I think Thomas Foolery or 'little Johnny' would like to hang out with the endless liars,about Synergistic (crap)fuses ,on this post. Thomas would enjoy the foolery; and little Johnny would chime in with 'it shows you're thinking- idiotic thoughts--but thinking nonetheless.

I'm with you wolf, details schmeatails. Some guy on here is even "biasing" his fuse. I think it's a case of the "looney tunes bin "calling 'stridently' - but with a little to much texture--and a 'not quite right' horn-ey sound.
Seeing it’s now fact by many having these SR mains fuses blow, that the melting point (which is the blow point) is wrongly overrated.

You take your chances…although I’ve been ranting seemingly for ages against SR’s overpriced examples of possibly dangerous audio tomfoolery, and have occasionally posed the still unanswered question, "why, and how, were they designed to do whatever they do?", the safety issue (as well as the fuse directionality myth and ridiculous imagined sonic benefit claims, as well as obvious commercial promotion by thin skinned "shill seekers") seems unignorable, which isn’t to say it won’t be ignored. "Damn the torpedoes, I want my tonally accurate cellos!" You can claim until the cows come home (they may never come home by the way) that special shoe laces make you walk better, or cryonically treated valve stem caps make your car corner faster, but logic may prevail when reports come in that the laces come untied causing you to fall over, and the valve stems explode causing you to crash. Hypothetically…or maybe not as regards SR fuses. Details schmeetails!
Al, they’re deliberately overrating their fuses, biasing the fuse higher into class-A, so it runs hotter, closer to the melting point, this voodoo will come next.
UNBELIEVABLE! This "Synergistic" fuse company selling products so poorly manufactured----- they can't even get the fuse rating right ! High quality fuse manufacturers such as BUSSMANN and LITTELFUSE ,who supply to high tech industries, would be bankrupted with claims. Charlatans and snake oil peddlars should be asshamed of themselves.......
I suppose it's possible that there is some relation between the apparently lower melting points of the SR Blacks, compared to typical stock fuses, and the sonic benefits that have been reported. But in the absence of a good technical understanding of why and how those benefits occur, that stands up when looked at quantitatively, and that accounts for the high degree of consistency that has been reported for those benefits among very diverse applications, I doubt that the question is answerable.
Is it possible that the same electrical characteristics that create the audible differences from these fuses also create the issues with them failing in certain circumstances?
Kedoades 1-14-2017 Hello, I am thinking of trying one of these black fuses. I see some people are recommending that you go one size up on the fuse, just wondering if this is always safe to do? thanks
Based on the several reports we have seen in this thread of SR Black fuses blowing when they shouldn’t, it seems clear that the unspecified "melting point" of SR Blacks is lower than that of typical stock fuses having the same current rating. ("Melting point" defines the combination of current and duration that if exceeded would cause a fuse to blow, and is expressed in units of amps-squared x seconds). Therefore it seems clear that if for example you were to substitute a "5 amp" SR Black for a 5 amp stock fuse you would in effect be substituting a fuse having a lower rating than 5 amps.
Also, from a technical standpoint it seems to me to be very unlikely that a fault in a component that should cause a fuse to blow would result in a current draw just slightly above the rating of the stock fuse. Especially in the case of a mains fuse, but most likely also in the case of DC rail fuses.
On the other hand, it might be argued that use of a higher fuse rating than stock could invalidate warranty and/or insurance coverage. But that too seems very unlikely. And in any event the same argument could be made even if the same rating as the stock fuse is used, just based on the fact that the upgraded fuse does not have approval from UL and other such agencies.
So IMO there is no problem going up one or two current rating increments. Although some others have expressed differing opinions earlier in the thread, and the post just above indicates that going up one or two increments may not always be enough anyway.
I bought two Black fuses for my Electrocompaniet amp. Selected higher than the suggested rating, two steps higher for the one inside the amp. They both blew in three weeks.
There was a difference for sure, more detail in the highs, it was showing problems in that area as well.
After they blew I removed the wrapping on the fuses, there was nothing except some glue in that "mystery dot". Maybe the glue is the thing, who knows.
I’m not getting new ones soon. Going to try some other fuses next.

A great CD with original and traditional American music is violinist Mark O’ Connor’s "Liberty!". It’s the soundtrack from the PBS miniseries of the same name about the American Revolution.
The track "Brave Wolfe", a duet for violin and trumpet with Wynton Marsalis, is particularly amazing.
^^^ I don't know if any of you guys have ever made the connection between country & western guitar playing and Hawaiian music. My friend Robert pointed the connection out to me a couple of years ago. Could it have been the influence of Hawaiian music on our young military boys when they served in Hawaii during WWII? Check it out:
I have Herbie's products throughout my system. Outstanding and very reasonably priced for the performance improvement they deliver. Customer service is amazing too!
^^^ Agreed, tommylion. Herbie's has a lot of interesting looking tweaks. After I finish with the tube dampeners, I think I'll try their little Black Hole carbon fiber CD mat. Nice reviews on that item.
Another shout out for Herbie's Audio Lab. I recently "Herbieized" my Audio Note AN-E/L speakers. I used the Square Fat Dots to isolate them from their stands, and I replaced the original spikes on the stands with Threaded Stud Gliders. Talk about clarity, transparency and natural sounding detail! If you are interested in affordable, cost effective vibration control for your entire system, I highly recommend HAL.
This was an exciting game .The speed and explosiveness of the players particularly on defense (both teams) was near NFL caliber. They can close in on you in pursuit just like the pros demonstrate every Sunday. Between these 2 teams there's definitely future NFL talent that was on display. Clemson recruits/selects players apparently just as the top SEC programs do. They guys can play!
