The New Synergistic Research Purple Fuses

@ted_denney 

Hi Ted,

here below the answer received from the dealer:

Hi Geoff,

I have spoken to SR and they Only do the 3.15amp fuse

My purples finally arrived today.

I need to remember to not order from the UK in December.

24 days to arrive.

@ted_denney 

You say I can put them in amp/Dac, power them up but don't need music playing through them?

I once knew a Robert...

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.

Yours in music,

I just changed Purple fuse into my PS Audio BHK Preamp and the sound opened, it was a huge improvement. Other 2 Purple fuses are on the way for PS Audio Stellar Phono Preamp  and PerfectWave Transport SACD.

Just one question Ted: why you do not produce 3A value rate fuses?

5x20 mm slow blow series comes only in 2.5A or 3.15A, not a 3A model available from any European dealer.

PS Audio engineer team in Colorado - I already asked them = said that I ABSOLUTELY MUST follow this spec for fuses in my PowerPlant P12 regenerators, only 3A value rate fuses, nothing else nor 3.15A neither 2.5A. It’s the EU schuko version of PSAudio P12, not the US model.

so I cannot use your Purple fuses right into the component which has the best performance in sound quality due to rolling fuses, and especially from your Purple fuses as reported from a lot of forum members here and folks of PS Audio forum.

thank you for your reply and if custom fuses would be available I’d immediately  buy them for sure directly from your factory. I love them after experienced how great they improve SQ in my system, congrats Ted.

happy new year (we all hope!)

Just finished listening to Prokofiev’s 3rd Piano Concerto with Martha Argerich, Claudio Abbado and the Berlin Philharmonic. A great performance of great music!

With fully broken in SR purple fuses in my CD transport, DAC and amp, it was definitely closer to being in the room than I have experienced before, with my system. This is also true with other music I’ve listened to yesterday and today; Altan’s The Gap Of Dreams, Mile’s Davis' Kind of Blue, and some of my favorite songs by The Cure, for example. Isn’t that what this hobby is all about?

I am really happy with what these fuses bring. IMO, in my system, they are a great value for the money.

@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.

If this is the case why do you include information that comes with your fuse telling you the current should flow left to right as you view the fuse from the S to R? If it’s just a lottery.

I have 4 fuses in each of my pre and power amps. It’s pretty ridiculous to expect someone to try each fuse in both directions each time you fit a single fuse in terms of time consumption (fitting and testing) whilst trying to mitigate expectation basis. Particularly as the difference between a fuse one way and the other is not night and day but relatively subtle in my experience with all audio fuses I've used (AMR, SR, Black, Blue and Orange)

Thank you for your input

@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.

I hope this helps,

Hi Ted, thanks for your message.

I thought the point of the fuse directionality was that the current should flow in the fuse in a certain way.

I am using a Farad Super 3 LPSU which is proposing your fuses as upgrades, and on the circuit board, there is an arrow for the fuse direction. When tested, the arrow is from hot to neutral so that led me to believe this was the correct way.

So I tested as a reference point and started to listen like this. I also tried to reverse but so far it sounded better this way.

Maybe you can tell us more about directionality?

Thanks,

@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?

yours in music,

My method to find out which direction the fuse should go is to use a mains tester on the fuse holder without the fuse in place. (when possible)

I place the fuse arrow from the hot to the neutral.

Anyone has further comparisons between QSA Yellow and SR Purple?

I have two QSA Yellow (one on a farad lpsu and one on a switch) and contemplating deploying two more, either yellow or sr purple - on my dac and my integrated.

I have no idea why, but the Purple fuse I installed the other day on my Innuos ZENith MK3 worked wonders. Shocking actually. A more audible difference than even experimenting with several expensive power cords for my Innuos unit. The fuse is one of things that should not make any difference at all, conceptually, but yet, it does.

Yes, the directionality can be confusing, but really no problem with Innuos, as they have a very good instructions page in fuses in their webpage: https://innuos.com/kb/replacing-the-fuse-on-innuos-products/

After 3 days and a swap back to the old fuse, I agree, something there. Better musical flow, image is cleaner, I feel like the overall sound is more satisfying. 

I'm with you ozzy. I have no idea why a fuse can make so much difference. It all adds up to a cheap upgrade. 

I am really digging the SR purple fuses with my tube amps. I still don’t understand how a fuse can make such a difference, but...

After 6 weeks, the music take another big step, full body sound.  I was realy surprise, I was thinking the breaking time was over. That is a very good surprise 

First impression very positive. Used Under African Skies by Paul Simon to A/B. No contest against the stock fuse in my tube integrated. I don’t have any experience with prior versions of fuses or other brands. 

The fuse direction on slow blow fuses is because they have a small diode at one end. The diode holds the incoming rush of voltage. If this type of fuse is installed the right way the high end is clean sounding. Not a dull sounding. 

Still a little confused as to the purple fuse direction on my tube mono block amps. This fuse replaced a QSA yellow in which the arrow on that fuse pointing from back to front.

The purple fuse was initially installed basically the same way with the writing going from back to front. The soundstage sounded ok, but the vocals sounded a little too warm.

So, I reversed the purple direction, now the writing is going from the front to back. At least at now (5 hours usage) it seems to have more detail, and the vocals seem to be more prominent.

I am trying a SR purple in my Request Audio Beast at the moment. Power Amp is a boulder 1160. The Purple is a huge improvement over the Orange but - it is very musical but for me a little bit too much. It tends to soften the sound in the whole frequency range. I prefer the QSA yellow which is more neutral and detailed. I will try a QSA Red next. 

Ordered a purple one for my amplifier. 

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.

 Hi Ted,

  I replaced my orange fuses with purple fuses and put them in the exact same direction as the orange fuses which I listened to for direction when I installed the orange fuses.

  The purple fuses made a big difference.  Would you suggest that I once again check the purple fuses for direction and not just go with what sounded good for the orange fuses.

  Thanks for moving the bar forward in developing the purple fuses. I took one of your dealers up on a free in home trial of your Tranquility pod that I placed on my pre-amp.  It didn't go back to the dealer. I don’t know how or why it works. I can say this it too made a big difference in the quality of sound.

^^^^^^^^^ This ^^^^^^^^^

@novemberman1103  Passing this along, sadly...

RIP ? Please clarify 

Oregonpapa ,

Because of your thread I went ahead and purchased the SR purple fuses to replace the QSA yellows in my mono amps.

First install, there is more wholeness to the music. I also coated the ends with NPS-1260.

Thank you, Frank (RIP)

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.

Ted

I am still troubled by directionality for multiple reasons ---I am functionally blind and my components are in a space where I can't get o them easily.  I have had all of your fuses except Purple.  I am considering Purple.  I have the QSA yellow now.  If I buy 4-5 Purples, does it make sense to initially place them into your component as follows:  if the ground is on the bottom the writing on the fuse would read L-R?  if the ground is on the top, the writing on the SR fuse should read R-L?  Or does the ground even matter?  

November

 just upgraded from all orange to all purple and I am absolutely thrilled and actually rather gobsmacked at the leap in clarity and detail etc 

How many components did you put them in?  Which ones?  Did you put them all in at the same time?  Did you put them in the same way?  Were you able to distinguish whether you put them in the right direction?  If you put them in one component at the time, did you hear a sound improvement with each component?  

So what is a T 10.0 L fuse?

I am a Hockey Bot.

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.

Merry Christmas Jerry. 

@jerryg123

I like when people have tried products/tweaks, and say from experience that the effects were minimal at best, or didn’t suit their system, as you have done.

Even don’t really mind those that ask "How can that possibly work?" (I still think that about fuses).

Just struggle with those who are argumentative, belittling, abusive, posts riddled with derision, and question others’ motivation, morals, intelligence and honesty.

I have some items I’ve bought where I question their efficacy. Unfortunately my location and purchasing style means I am unable to return items.

Ted.

All is good and I agree.

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

You don’t possess an enquiring enough mind to wish to be ‘educated’ in the science behind this phenomenon?

I'm sure ASR is more the forum for your assaults.

You take over threads. Your 'enquiring mind' is harassment.

You say nothing that interests me...

@tsushima1 Okay then...sounds like you are the rocket surgeon and should be making the case against the directional attributes of a fuse.

Me I could care less thought I was helping.

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

and EE can not explain it here Lucy.

@jerryg123 

That is not an answer to my query based in known physics … It is marketing verbiage 

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.

@tsushima1  Here is your answer from @ted_denney web site.

Ted would have taken you 2 seconds to type this.

I think I may try a fuses again just not sure who's

@ted_denney I was not voicing an opinion on your fuses. I have tried fuses in the past (not yours) and guess what they did nothing. I am not going to name names and I am not condemning your product.

I simply stated 'There you have it" and you got twisted, not me.

I am willing to give them a try at some point but have no idea where to begin.

So there you have it.

Merry Christmas Ted.
