The New Synergistic Research Purple Fuses

I've seen input here re: the directionality of fuses and the need for burn in.

Question: If I install a fuse in the wrong direction will it eventually "burn" into the desired directionality?
 

No

Fast blow fuses don't have direction. 
 

All fuses exhibit audible directionality. Fast or Slow blow matters not.

“ All fuses exhibit audible directionality. Fast or Slow blow matters not. “

How is that ? 
 

The answer is clearly contained in my quote you cited. No further explanation necessary.

@jerryg123  yes, all fuses exhibit directionality when you listen. It’s the last part, when you listen, that some people have a problem with. I don’t have time for people who won’t listen to something, but will argue about that same something for months and even years online. Especially in light of the fact, we have a strong dealer network, with an airtight 30-day no-risk moneyback guarantee. Anyone who would rather argue that fuses don’t make a difference, or are not directional and can’t be bothered to listen; I can’t be bothered to respond to respond to that. 

So… You have absolutely no idea why then ?
 

No, I know why.

Guys and gals some people are best to simply ignore. 

Jerry my response (to your post) was to clarify my position, I was not upset by your question. That said, I don’t waste time arguing against spurious circular arguments put forth by individuals hiding behind anonymous names on audio forums. Real audiophiles are enthusiastic about their stereos, their number one objective is to get better sound. Real Audiophiles know the only way to determine if something sounds good is to listen. Measurements are not an end, but only a means. I focus on people who are actually into stereo, not those who like to argue endlessly on user boards, people who don’t have top-notch or even up to snuff systems 99.9% of the time because without making decisions based on subjective listening tests, it’s not possible to have a great sounding stereo.

You just have to listen, one by one. If you’re currently putting in fuses yourself, changing direction shouldn’t be too much trouble or if it is, have a friend help. This is true for all fuses specialty or otherwise, and is always best practice.

If you stick one in and flip it and it sounds better there you have it Physics.

Merry Christmas Jerry. 

November give the purple Fuses 72 to 96 hours. And you don’t need music running through the system, just leave equipment on where they’re applied. They will be smoother/more musical than Orange after they settle in.

Simguy the best practice would be to replace one Orange fuse with a Purple fuse one fuse change at a time starting in the same direction. If the new Purple fuse immediately sounds better in most ways over Orange in the same orientation, then simply go to the next fuse location, no need to listen in both directions. If however you encounter one application or two where a Purple fuse does not immediately sound better in most ways simply reverse direction. Again you don’t need to listen both ways with all fuses, only when a single Purple fuse is not a significant upgrade in most ways over an outgoing Orange fuse. This is down to a new long duration high-voltage conditioning process first developed for SRX cables.

I hope this helps.

@steph_alex The way to determine fuse directionality for a given circuit, at least for best sound quality, is to listen to a fuse in both directions and select the direction that sounds best. Interesting that you choose a different path, but how do you know if the measurement you’re taking correlates to best sound quality? Or do you ultimately listen and if so, what is the point of taking the measurement?

@steph_alex

Electricity will flow regardless. The reason to pay attention to fuse directionality is to get better sound quality. And because directionality is ultimately determined by what sounds best in the complexity of not only a single circuit, but in the complex interaction between components in the system as a whole, there really is no better way to determine what sounds best than to listen. You can of course measure, but you’ll than need to listen to confirm your measurements correlate to SQ which is subjective. For these reasons it seems straightforward to simply listen and make the call on a fuse by fuse basis.

@clifton below is what our website actually says regarding how to place Purple fuses for best performance.

Note:  If you are switching from an Orange fuse to a Purple fuse, start by inserting the Purple fuse in the same direction as the Orange fuse being replaced.  If the Purple fuse is not an immediate improvement, flip the Purple fuse in the alternate direction.

 

 

Luca,

Buy a PowerCell? Just kidding. If you have the dealer you purchased your other fuses from contact us, we may be able to build what you’re looking for. Not sure as I’m not at the factory. Hope you had a merry Christmas, and a wonderful new year.

Luca what are the exact fuse specifications for your PS Audio regenerator? Size/value/fast or slow. Also if you know, is this a common value for their conditioners?

Luca,

SR fuse tolerances are VERY tight. Much more so than standard off the shelf fuses. We have never had a complaint that they did not blow when protection was needed. in fact if we are getting complaints, it’s that they are more protective than standard fuses. That said, I will look into building a 3 amp fuse but honestly I cannot imagine our 3.15 amp fuse not blowing when an off the shelf 3 amp fuse blows. Still, it’s always best to go with manufacturers recommendations regarding fuse values.

A member no longer on A'gon would say that it was because all wire, including in fuses, is directional due to the extruding process.  Hoping you can shed some light on this.
 

That is the prevailing theory, yes. It is also a predictable and repeatable phenomenon. The only complicating factor, when a cable in an audio system has multiple conductors, if all conductors were not aligned for directionality, so that they are all in the same direction relative to their pull or cast as formed, determining directionality becomes splitting the difference between how many conductors are going in one direction and how many in another which can make differences less dramatic. But when you have a single conductor, or all are aligned, it’s incredibly easy to hear the difference.

@lucapelliccioli after researching with a handful of US dealers and audiophiles we have found that many have 3.15 amp fuses presumably stock or from the factory. I understand you don’t feel comfortable putting in a fuse that is .15 amp over rating, and we respect that. But it does not appear to be a problem from our query. 

@kclone you did not hurt the fuse but please give it 24 hours, you don’t necessarily even need to play music, just keep the component on which will keep the fuse powered up and listen the next day.

Don’t raise your values. Go with factory specifications.

Actually just having your system turned on, or even the single component you are re-fusing left on (it is always a good idea change only one component fuse at a time until you determine correct fuse directionality) is sufficient in most cases to burn in a fuse, no music necessary. It is paramount however that you first determine correct fuse orientation on a fuse-by-fuse basis before placing in the next fuse in your system and again listening in both directions where the correct directionality should be readily appertains as more air and detail. If switching from a prior SR fuse model like Orange start Purple in the same direction, if it does not sound immediately better in most ways simply reverse the Purple fuse direction. Due to a new conditioning process, purple fuses may not always perfectly mirror the same orientation as prior SR Fuses. After determining the correct directionality for one or more fuses leave your system turned on to speed realization of best performance.

With so many hobbies to choose from, I do not understand why people who cannot hear the difference between most things in a stereo choose High End audio as a hobby in the first place. I mean if you can’t trust your own ears, how do you know a pair of Wilson speakers sounds any better than a Bose Wave Radio? Or if human hearing is so insensitive that it can’t discern differences in what it is that makes up a stereo, why spend good money on a high-end stereo in the first place? And what I have the greatest difficulty understanding, is why people who don’t hear differences care about what people think who do hear differences. When did we become a society bent on making those whose opinions are different from ours conform to our way of thinking? It's very odd.

Andy, SR had nothing to do with this thread being reinstated (again.) We also have zero for sale on AG. To my knowledge my company has never sold anything on AG nor do we advertise our products here. Your link is a compilation value servic based on past AG sales of older used SR gear paid for by AG users, my company has zero to do with this. My guess, AG contributors who are also SR users contacted AG as to why their posts on SR fuses were consistently getting taken down.

The ’directional arrow’ is the direction of text on an SR fuse and is consistent from one fuse generation to the next. Reading left to right direction or signal starts at the beginning of the writing. What is unknown and what cannot be known without a test is the optimal direction in a specific component that will sound best. For this you really need to listen whether you have arrows or text on a fuse. This is because electricity does not *flow* like water but rather energy propagates abov/around the filiment/wire. When our straightforward listen in both directions per individual fuse guidelines are followed with any fuse, optimal performance is achived. Optimal directionality is discovered not for the fuse, but for each component, something that cannot be known until the experiment is performed. Bottomline if you want best performance in your audio system you need to work at it, and this is true for everything, not only fuses.

Perhaps this will help:

These guys creating profiles to dog pile this discussion forum belong to an audiophile hate group on Facebook; literally a group dedicated to laughing at people with much better stereos than they can afford, with technologies they fail to comprehend. And being insecure they imagine we too are insecure and so fear what they think. Their intention is to derail this thread and get it deleted. Perhaps they are the ones who will get deleted?

Audiophile hate group on FB? Sounds like a conspiracy theory to me.

The user who taunted Frank as being an object of ridicule on his Facebook anti-audiophile hate group currently making fun of this thread, with members creating profiles to troll in the comments, mentioned the name of the group. I will give them no such publicity.
