The Synergistic Research Orange Fuse ... Further thoughts.

Hello Nutty, thanks for the response. I worry about interfering with the original equipment. I recently purchased A Mac C53, so would hate it to "affect" warranty, etc. With the Mac I would have to remove the chassis, donmt want to do that. My dealer said he would do it. If it's worth it, I would try it, otherwise, I'm very satisfied with the sound and performance.

Hello Steve - I have easy access to my fuses on my Naim and Teddy Pardo gear.  They have a small drawer next to the IEC inlet. Other components has different access points. Mine were very easy. I've had two Purples in my system for close to a year and they are still at peak performance.

Arriving late to the discussion! My dealer suggested trying the new SR purple fuses in my preamp. If they are worth it, $200 isn't too bad for a tweak. But has anyone had to remove them or had trouble after installing them? what is the longest period any of you have had the same replacement fuses installed for in your equipment?

Steve

Hello jerrybj -

Thanks for the inel in the alternate fuses! I appreciate your guidance.

Yesterday I ordered two Synergistic Research Purple fuses from Chris at VH Audio along with two Furutech plugs to reterminate a power cable. I’m looking forward to comparing the two fuses. If the Purples don’t deliver I may dig deeper into alternatives.

@nutty 

I have a friend who has a masterful system.

He offered advice regarding DC fuses for linear power supplies. His findings, from a range of SR fuses red/blue/orange/purple is that the best fuses he found for LPS were HiFi Tuning Supreme. I bought AMR Gold due to available funds at the time, but will end up with HiFi Tuning Supreme fuses for my three LPS'.

Sorry @nutty 

I haven't had my system up for 10 months, and have made many changes in that time.

When I get it up and running next month, the differences will not only be in the fuses...

(Dac, streamer, ethernet, network switches, power treatments, grounding box etc).

Hello jerrybj - I'm interested in your impressions between the Orange and the Purple fuses. 

N

 

I have gone from SR Black to Orange to Purple on my amp.

SR Red to Orange to Purple on my Dac.

Gave them 250-300 hours running in each time.

 

I’m running two Synergistic Research Orange fuses in my system. One on my Naim Supernait 3 and on my Teddy Pardo TeddyCap SE power supply. I’m in agreement with oregonpapa on almost every aspect. However when I did a comparison on the Supernait 3 fuse vs the Synergistic Research Orange I found the Naim has better quality bass and attack. The Naim is more robust in that arena. However the SR’s have exceeded my expectations. I’m also running a Teddy Pardo power cable on the TeddyCap SE. It is terminated with Furutech FI-50 Rhodium plugs. It’s highly resolving ;^)

I do have the ability to upgrade my Naim nDAC and the Teddy Pardo XPS power supply as well however the nDAC/Pardo XPS combo sounds excellent as is. I also have a Teddy Pardo power cable on the Teddy XPS.

 

Not sure if I want to get used to it.  Ill give it one more week.

Your ears will get used to it.

Bumping an older thread. Though I’d give an SR Orange fuse a shot. I’m currently trying one of these SR Oranges in my Rogue Rp9, comparing it to a Hifi Tuning Gold that I got on closeout. I do not remember what the stock fuse sounds like (plus my preamp has since been upgraded). Honestly, the SR Orange sounds worse than the Hifi Tuning, with the Orange having some grain in the treble and what seems like a compressed soundstage. Yes, I tried it oriented both ways, and there was no difference. Gonna give the Orange more time, but my experience with "break in" is that if you don’t like it out of the box, then improvement won’t be enough. Just my observation.

I have 6 in total, 1 on the wall directly in front of me, 2 at the first reflection point of the speakers. 1 directly behind me and 2 more on either side of me where i sit.  In my room, what they did was make the soundstage wider and more pronounced. they separated the instruments more if you will. I am hearing acoustic guitars and snare drums more focused off to the sides. It sounds like i am surrounded now, and that the stage has disappeared. It is hard for me to explain as i may not know all the correct terminology. I just know that there was a significant improvement.

Now i also tried them in the basement on my second system, and there was no change that i could hear at all. So each room will be different. The dealer i bought them from was surprised with that. lol

@hilroy ---what did the SR frequency Transducers do?  I have 18 SR HFT's and I really don't see a change.

I have the Sr orange fuses in both of my systems, and 9 components in total. I bought them all at the same time, got 30% off . Was a $1600.00 investment, and well worth the money. The fuses were the last tweak in my system. I don't have the 200 plus runtime hours on them yet, but there was a noticeable change instantly. 

One of the best investments i made was room treatments. I have roughly $50,000.00 worth of gear in my main system listening room, i bought Vicoustic diffusers, and 2 sets of SR frequency transducers. For $2000.00 they changed the size shape and sound of the soundstage & presentation the most. I have absorption panels in place as well. My room is 13 feet x 19 feet, and i feel like i am sitting in a huge concert hall. I have taken great efforts to be thoughtful as to what i have added to my systems to achieve the sound i was looking for. A Saturn 103 C power conditioner with all good quality power cables, has given me a ZERO NOISE FLOOR. I hear dead silence in between beat of music or lyrics sung. The room is as critical as the gear, once you get them married, it is musical bliss.

 

Did you find the sound mellowed after the break in period for the fuse? I do like the sound but I’m finding it a little harsh or cool sounding. 
Thanks in advance 

How about breakin time on these orange fuses ?
I have 50 hours on them and the treble is tilted at least 15% higher 
then when I had the stock fuses in there.

Your sourse components do first ,since the music starts there it is the most critical part of the chain.
nobody speaks of runin time Synergistic says 2-300 hours. 100 hours brings it over 90% 
always should  if possible Go to a bit bigger size for these are accurate and Can blow  ,standard buzz fuse can vary over 15-20%, I found out the hard way with earlier versions.
theone in mySchiit Yggsdrasil made a very noticable improvement 
my preamp section nowreplacing orangefrom blue , very overpriced imo, but worth it. Also as far as snake oil comments 
great electronics Gurus like John Curl, and Nelson Pass as a small example has used them ,and they may know a thing or two about Electronics engineering !! There is on average 4 x less resistance  from these top fuses vs the steel,zinc fuses,just lookup metals resistance index .the steel fuses are a bottleneck .

Need a little help if I purchase orange fuses in what order should I replace them for the best bang for the buck and a few words on why. Would it be AMP first then the preamp DAC phono stage?

I have a BHK 250
             BHK Pre
             Perfect wave DAC
             Stella phono amp
             Power Plant 20

Pass Labs for my home theater 
Someone suggested don't replace the rail fuses in the 250

Thanks in advance 

I am also in the process of upgrading fuses in my system from mostly Synergistic Blue to Orange.  There are a couple of questions that I wanted to ask those with experience with these fuses:

- Given the same fuse generation, does a higher Amperage fuse sound fuller and better than a lower Amperage fuse (eg replacing a 500mA fuse with a 2A fuse) ? I assume the higher rated fuse has a thicker filament and could actually result in a better response.

- Is there any way to accelerate the burn-in process? The 200-300 hour burn-in process for the fuse means that I put in 200-300 hours on the very expensive and hard to find tubes that I have in my equipment before I get good sound. And, to compound that, since I will be upgrading my fuses gradually, this means that I will be putting in many hours on the tubes in my DAC, preamp, and amp before the fuses are burned-in. By then, the tubes have aged considerably, which is very concerning.

I have the synergistic blues fuses and are very good ,in my preamp section I tried the orange a  3-4% better then the blue but.currently $70 more per fuse and I needed 5 ,solution 
i use Furutech nano fluid which uses nano particles of silver,gold  i use a small foam swab and coated the fuse holder contacts good which contacts are crap and this alone gave a noticable boost in detail 
it takes a few weeks to dry but gets better over the few weeks 
others I know that have used it agree, even on power cords ,both sides .on ebay I get it straight from Japan for $120 delivered vs $170 here and it goes a long way and BTW synergistic uses brass 
nickel end caps ,Hifi tuning use silver,gold.it says right on the synergistic site ,it not the best conductors ,vs silver,gold
that’s why the Furutech nano fluid makes a noticable enhancement it goes into the pours of the fuse,and holder.and save $$

9. Lastley, I can set the volume control lower and get the same volume in sound as before.

First..."lastley" isn't a word.

Second, are you willing to have this statement proven via measurements? 

Overall ... the new Orange fuse is a real winner in my system.

Highly recommended.

Frank

Frank, oregonpapa was evaluating Orange prototype fuse for Ted Denney (Synergistic Research). His hype "testimony" is just advertizing material, very pathetic . Any credible opinions on Orange are welcome. 

So a while back I had some sr20 fuses and some hifi tuning mundorf fuses..they both had a different effect in my system and I preferred the mundorf over sr..until the black fuses came out the changed my mind about synergistic fuses. .when the blue fuses came out I jumped in without hesitation. Even bought the blue duplex and some blue power cables. .needless to say I have 3 orange fuses arriving today to place in my amplifier and I'm looking forward to hearing the improvements. Guess I'm a sucker.lol!

ieales440 posts10-19-2019 3:26pmFrom SR:

Electricity should flow from the left to the right when you view the fuse.

A/C current changes direction every cycle. The supreme idiocy of the statement: what if I view end on???


>>>>While that’s true, and for virtually all cables and power cords - the current alternates. 🔛 But you can ignore 😳 the current when it’s traveling in the direction toward the wall outlet. 🔜  The only direction we care about is the one that drives the speakers. That’s the direction that is audible. 

@tom8999- You’ve already heard the differences, you’re other upgrades have made. You know you can trust your ears. SR offers a money-back, satisfaction guarantee. Experiment safely, with nothing to lose and, very possibly: enjoyment to gain. I’d just try the Krell’s Mains fuse(under the IEC) first. I would next try the Krell’s two speaker fuses(under L/R speaker connections). Have you upgraded the Krell's power cord yet?  If not, do that first.    Far as the Maggies, I've always bi-passed(have owned four pair) the fuse & attenuator stuff, entirely, so- can’t tell if a better fuse helps. I wouldn’t expect a big difference, in that circuit, though(just my opinion). Does the Krell have rail fuses? Of course, if it’s new; opening it would void the warranty.

From SR:

and

UEF Tech is so powerful even an electrical chain several miles long is fundimentally [sic] improved with nothing more than a single fuse engineered with our patented UEF Technology

Prove it. Set up two chains. A/D them simultaneously for 200 hours @ 32bit/384kHz. Replace 1 fuse. Repeat. Show us the deltas pre/post and over 200 hours.

If there's one thing I've learned, it's that systems [couldn't possibly be me] are rarely the same...

Nobody that is nontechnical should be going inside any piece of audio equipment and touching mains fuses.

This is an accident waiting to happen if someone needs to ask how to replace all his fuses for these orange voodoo fuses.

Some day somebody is going to forget to unplug the mains cord, take the lid off his equipment and grab that fuse with is fingers🤦‍♂️, it’s probably already happened we just don’t get to hear about it.
Are you then oregonpapa/SR going to put your hand up as say, it’s our fault?? I think not.

Cheers George

Oregon papa - I need very specific advice as to how to implement the SR fuses into my main system, if you do not mind. I have reached the decision to try them out.  My equipment is as follows:

Lumin D 1 - this is my main source - no fuse port
Krell KAV 400xi - AGC 8 fuse port
2 Maggie 1.7i - Type 3AG (4 amp max)
Maggie DWM Panel - no fuse port
Son of Ampzilla II - no fuse port
Furman Elite 15 Power Conditioner - no fuse port

i assume I need three Orange fuses or should I just do the Maggie’s?

Based on multiple threads here on Audiogon - over the last 6 months I have upgraded my interconnects (Anticable), High Fidelity Cables - MC0.5 Power Conditioner, and the Furman Elite 15. Every time I introduced a change my sound has improved. I guess I am hoping for the same here.

any advice is appreciated.
Tom 8999

This hobby is almost entirely subjective....bottom line is try it and see if you like it more ...if you are happier that is what is important

Now perhaps it's not truly better but just different....perhaps more synergy with rest of equipment or room or just your subjective taste...you like it more that is what matters....

If you want to experiment more it's fun to try and if you are tired of trying new things or feel you got perfect balance then no need to try it.

david_ten = +1(for diligence, growth and learning)  Never stop experimenting!

oregonpapa, millercarbon & SR = +1(each)

I used to be amazed, that those complaining about aural memory, knew who’s on the other end of a phone conversation(before Caller ID).   Even(possibly) after years of not conversing with the person.    A good man recognizes his own limitations.    A wise man knows; everyone else is not, necessarily, likewise limited.

  millercarbon ... +1

Two appropriate Nikola Tesla quotes:

"I'm not disappointed that they stole my ideas ... I'm disappointed that they have no ideas of their own." 
-----------------------------------------------------------------
audiotunesx ...

Yes, the bass is considerably better. Acoustic bass becomes even more natural and tuneful. Everything is better with the Orange fuse. Percussion takes on a new life as well. 

Frank

Is the low bass in still as good as the prior blue fuse?  

What amazes me about threads like this, even more than Ted's incredible ability to continually best himself, is how eager and diligent some are to tell us all in no uncertain terms just how awful they are at listening and remembering what they've heard. For damn sure if I was that lost at sea I'd want to keep it to myself. The last thing I would ever want to do is try and act like everyone else has to adapt to my lack of ability. But no. I can't tell, so you can't either. A perennial fave. Amazing.

A big +1 here for SR, and highendelectronics.com
For those who can hear the difference.

^^^^bravo...hope you’re being compensated for your relentless PR efforts. 

allenf1963

The fuses are used in your electronics, like amps, line stages, phono stages, and speakers that use fuses like Maggies.

The Orange fuse under discussion here is made by Synergistic Research in Santa Ana, California. The owner and lead designer of SR products is still Ted Denney.

I’ve been on the other sites you mentioned where some members excoriate Ted Denney. He’s actually hated by a few members on those sites.

Those calling Ted Denney’s products "snake oil," for the most part have never tried SR products. They are people who lead narrow, darkened little lives and take pleasure in talking out of their heinies.

These are very destructive people, not just on the audiophile sites, but destructive in general as they wander through life without a positive focus, or a second thought about how much they hurt others ... all for the cause of making themselves feel far more important than they are.

To paraphrase Nikola Tesla ... "If hatred was electricity, they could light up the entire world."

If you were to go back on earlier fuse threads, you’d find that the Orange fuse is the latest SR fuse to hit the market. Prior to the Orange fuse, there are A’gon threads on the SR Red, Black and Blue fuses. Each one was an incremental improvement over the others.

While $160 for a fuse seems expensive, especially I would imagine to someone like yourself who has been out of the hobby for a while, you can be assured they are not snake oil, and that they perform well beyond their price point.

There’s a 30 day trial period with a 100% money-back guarantee. If they do nothing for you, then you’d be out only the cost of return shipping.

I’m the first to admit, after being out of the high end audio loop since about 2000 (had to take a break or lose my sanity), I am basically a newbie again. So much has changed...and yet it remains the same. I see the same arguement about cabling that was going on in 1978, 1990, and 2000 is still going strong.

But this "fuse" debate has me baffled. Can someone give me a quick breakdown on what is being discussed? What product are you changing fuses in? I only know of Synergy Research by what I have seen in Audiophile forums and chat rooms, and it is one of two extremes -- love Ted Denney or consider him and SR as nothing more than snake oil. I take it that Ted is the person who started SR, but all I know about the company is it sells power conditioners, high end cables, and other products I’m sure. I have no opinion one way or the other because I am not familiar with their products nor have I used them. I don’t praise or demonize anything that I have not tested myself.

Again, I would appreciate an education. Many times when you ask this type of question on these forums, all you hear is "That is what the Internet is for" or "Try Goggle". The problem is, I don’t know what to search for...I don’t understand "Orange Fuses" from "Blue Fuses" in the context of this discussion.

Thank you.

Allen

Well said! @david_ten. 

There is a wide divide between believing and knowing, at least there is for me. 

As @analogluvr  points out:

There is always a need for a/b comparisons.

In my experience, I have learned that my audio memory is suspect (if I am only going by it) and it becomes progressively problematic the longer the time between event A and event B.

I've learned this by evaluating my gear with direct and repeated comparisons across (nearly all) of my system changes. It's really hard work, but the rewards are significant and the growth and learning well worth it and in some cases priceless. 

I say this despite being intimately familiar with my system and having spent thousands of hours with it. 

My advice to members is to test and question yourself and your approach to audio more vigorously than your gear.

^^^ I've been more than satisfied with ARC. Been a customer since the early 1980s. As stated before, I  no longer chase the upgrade path. Only tweaks for me from now on. 
---------------------------------------------------------------------------------------
My friend Robert gifted me with the 180g reissue of Dave Brubeck's "Dave Digs Disney." I played it for the first time tonight. Dead silent vinyl and sounded great. I could have reached out and touched Paul Desmond.

Frank

@oregonpapa 

Do we hear the same irritations when other manufacturers upgrade their equipment?

Absolutely! That's certainly one of the things that bugs me about ARC is their creation of a perpetual 2-year upgrade cycle.  I much prefer the approach of Pass or VAC or Herron or Kuzma for instance who only introduce new product versions when there is a something of substance to present (in my view).  

@oregonpapa Frank, thank you so much for your response, it’s thoroughness, and for answering my questions directly, honestly, and fully. I respect and appreciate that. Thank You!

I’ll comment more in a subsequent post because I would have conducted the same or a similar ’evaluation’ differently than you did.

I do not have the HFTs nor do I have any direct exposure to them. Everyone who has implemented them in their systems (that I know personally) has also strongly suggested my using them. : )

My investment in and experience with SR has been in power conditioning, grounding, cables, and isolation.

^^^
I remember when I swapped out the KT-120 tubes in the REF-75 for the KT-150s. No need for a/b comparisons there at all. Nor was there any need for a/b comparisons in swapping out the SR Blue fuses for the SR Orange fuses. In both cases, the improvement was immediate and very obvious.

Frank

There is always a need for a/b comparisons. 

david_ten ...

I appreciate your questioning of my methodology in testing the new fuses. You are totally correct in doing so.

1. Yes, aural memory is fickle and tricky. The fuses were stock, right out of the box. Even though they weren’t broken in, they still sounded better than the fully broken-in Blue fuses that have been used for the past two years.

I don’t think your point about aural memory is valid in this case, because I am so familiar with my system. I can clearly hear differences every tweak makes, both for the better or if it degrades the sound. If I were testing fuses on an unfamiliar system, then I think your point would be valid.

2. No a/b comparisons were made. Not necessary. See #1.

3. Same as above.

4. Directionality checked? Yes .. I had to reorient the one in the line-stage. There was an improvement in overall focus. Slight, but better.

5. I did compare the Blue fuses one component at a time. With the Orange fuses, I tried the experiment of loading them all at once, so I could hear their total impact immediately. I was pleasantly surprised. Over time, say 20 hours, they improved quite a bit. Now that some weeks have passed, you’d have to pry them out of the system. I think at this point it would be akin to pulling out a couple of my ribs. :-)

6. See #5,

7. The "Stop It" duplex plugs were completely broken in at the time the fuses were tested. Normally, the "Stop It" duplex plugs need no break-in time at all. Those are the ones presently on the market... fully cured and broken in.

The ones I received from Tim weren’t cured like the ones on the market now. Using the "Stop It" duplex plugs prior to curing, or completely drying throughout from the manufacturing process, I had lost most of the mid-bass and some the lower bass. As soon as they cured, everything came back much better than before. That’s when I reported that they were like "putting ’The Gate’ on steroids." So, by the time the Orange fuse testing began, the "Stop It" duplex plugs had no effect (plus or minus) on the fuse test.

You mentioned that you are invested in SR products. I don’t have a lot of SR products, but the ones I DO have, the improvements afforded by them were immediately apparent. I remember when I put the ten-pack of HFT’s throughout the room as directed. Wow! That wasn’t subtle at all. In fact, in spite of having a lot of expensive room treatments in use (Bass Traps and Shatki Holograms) prior to installing the HFT’s, I had a bear of a time getting my room (raised foundation) under control. The HFT’s had a profound effect and actually completed the room. There was no need for a/b comparisons with the HFT’s ... just as there was no need for a/b comparisons with the new Orange fuses.

If you have SR’s HFT’s was your experience the same as mine?

Take care ...

Frank

@oregonpapa Frank, I need to challenge the methodology of your ’comparison’ as I understand it (post your clarification).

I believe it is especially important since you have self identified yourself as a beta tester and have shared your findings across 3 threads (if memory serves me).

Please know I am not disputing your findings (yet)...they may well hold...but I am now questioning them.

Please know this is coming from someone who is far more invested in SR than I believe you are.

I’m also familiar with SR’s improvements (and track record with new introductions) as one moves from a previous generation product to a new one.

If I am incorrect in what follows, please offer your corrections.

1. Audio Memory is fickle and tricky. This holds even when the comparisons are close in time. Removing 4 fuses in 4 different components takes time. Installing 4 fuses takes time. Having the components settle after being off and out of system takes time. Break-in time for the fuses, though shorter now, does add another time element. Were your fuses stock out of the box or were they specially broken in for you?

2. To A/B a single change isn’t easy. 4 changes simultaneously is quite a feat.

3. I’m assuming you did not A/B/A and repeat (?)

4. Directionality? Was it checked? By specific component?

5. Was there a reason why you did not compare the fuses one fuse/component at a time? In other words only one new orange fuse in the system with 3 blue fuses. Times 4.

6. Was there a reason you did not take a stepped approach. One component, then two? For example, starting with the most upstream or most downstream component.

7. Was there overlap with your Stop It applications? From your posts, it appears so. If that is the case, how are you separating out contributions from one or the other and both?

Thanks.
