Synergistic Red Fuse ...


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?

The Synergistic Research fuses- the Original and the RED fuses have been a big improvement in my systems. I have heard a significant improvement with the following: amps-Jadis, Art Audio, Triode of Japan, Eddie Current ZanaDeux. CD player-Marantz SA11S2. Dac- Antelope. Self powered subs Gallo and SVS.

I have compared the SR fuses to Isoclean and Furotech. I much prefer the Synergistic Research improvements.

Finally they are one of the few companies that allow and encourage a 30 day trial.

They sound good right out of the box and reach their maximum improvement after a week of having a signal run through them
Very nice discussion of fuses so far. I think along with fuses the other change that can make a significant difference in the over all character of a system's sound is the A/C wall socket. I am currently using 4 Synergistic Research and 1 Furotech GTX-Rhodium duplex on my system's circuit.
I really do like the fact that Synergistic Research gives you a 30 day trial to find out what works best for your system.
Charles 1:

Congratulations on a wonderful taken path to sonic improvement. The wall A/C receptacle and equipment fuses have a significant effect on the sound produced by the system. 

Once an audiophile has these bottlenecks removed the sound is so much better.

And finally overcoming the fear of changing a wall receptacle or a fuse in a piece of equipment is actually quite liberating!

audiolabyrinth:

Although you do not have fuses, Installing the Synergistic Research Electronic Circuit Transducers (ECT) in your CD player may result in a major improvement in sound. I have them in both my SACD players and they are effective. Same return policy as the fuses and removable if you sell your player. The fuses + ECT's in a cd player is very nice.

tzh21y:

Three screws in back secure the lid. After removal the lid slides back about 3/4 inch and then lifts straight up and off. You will have to use a thin Blade screwdriver to get the lid to slide back. There are 7 fuses in your player. I have replaced all  7 - great improvement. But you will get a significant effect replacing just the main power fuse. I suggest using a 3 amp small slo- blo BLACK fuse instead of the original 2.5 amp fuse. Fun to look inside that player. I like mine !!

r_f_sayles:

I would suggest replacing only the 5 amp fuse at the IEC inlet. On my OTL Eddie Current Zana Deux headphone amp this made a nice improvement.

David Pritchard
mid40sguy:

Glad you put ego aside and tried the fuse both ways. The fuse direction is proof that one should not let the laws of physics formulated in the 18th and 19th centuries be our only guide to sonic improvements.

Spent a couple of hours googling "Graphene". Interesting stuff. Hard to make in big sheets but easy to make in little flakes . There is graphene on or in the BLACK fuse. I am sure we will see adhesive dots of graphene to place on various components soon. Maybe a new type of WA Quantum Chip coming.

I think your fuse will now gently improve over the next three or so days.

David Pritchard
A reminder to all satisfied "Black" and "Red" fuse users. These fuses help the TV systems also. I put a "Black" fuse in a ZVOX sound base that sits under the TV and it definitely was worth the effort. Movie dialog and music were improved. Increased clarity.

David Pritchard
Yes the Synergistic Research ECT (Electronic Circuit Transducer)  are very effective on pre amps, amps, and front end devices such as DAC's and CD players. My SACD player and amp each have 7 of these small cylinders on them. The nice thing is they are easily removed when it is time to upgrade a device and then use on the next piece of equipment.

In order of upgrade I would do A/C wall receptacle, then main power fuse of each piece of equipment, then ECT, and finally secondary fuses.
charles 1dad:
I hope you will consider installing your outlet outside of your music system circuit and run current through it for a week. Then put it in the audio circuit.
I am glad the Afterburner is getting conditioned on an Audiodharma conditioner. I do think it is the best approach. I think a week will do it as there is not the Rhodium plating. It might sound a bit bleached or dry when first installed but will be settled in at the end of a week. I like the Oyaide frame and outlet cover. Remember to use the Afterburner cover plate screw and not any supplied by Oyaide. Might be US versus metric.  
taters:
Thank you for the correction.
Audio Magic makes the $175 beeswax infused fuse for $175.00.
I can find no information about returning this fuse for refund.

Audio Horizon makes an audiophile fuse. Most are $117.00
They carry fuses up to 15 amps rated.
They offer a 15 day trial and return policy to established Audiogon members.
I heard it at this years Rocky Mountain Audiofest and was impressed. The Synergistic Research Facebook page has a good description of what it does.

David Pritchard
Oregonpapa:
I think the "RED" fuses give the most significant change in the system of the various devices we have discussed.

The Synergistic Research ECT's  (for me ) reduce grain and hash. When the right locations are found, the sound becomes better focussed but still is full bodied. My Sacd player, and three amps each like about 7 ECT's installed. It is trial and error where to place but the change is immediate whether it is a good spot or a bad spot. For me they really have let me fine focus the systems.

Nobody has published how the WA Quantum Chips work, but they do affect the sound. Not universally for the better.

Interestingly they even work on acoustic instruments. I know because I bought the music instrument chip for my son. He is an all state high school viola player!  He, his instructor and myself could all hear a change. "The viola had more presence".  I liked the sense of "more" . My son did not.
audiolover718

Congratulations on your upgrade. I am convinced you are going to hear your Sony really open up in the best possible way. Going from Furutech to Synergistic Research "Black" fuses will be a positive major change.

Plug in those power cords and give them 150 hours to break in!
No fair peaking. Hard to resist though!

David Pritchard
Charles 1:
I hope you are able to first install the Synergistic Research RED fuse in the DAC and then Install the Afterburner A/C outlet.
I gentle reminder when changing the A/C outlet, circuit breaker turned to off and take the time to clean those household wires.
We do not need any shocking results!

I have spent a lot of time investigating the WA Quantum Chips. They certainly do cause a sonic change. For me they tend to give me a sense of subtraction. A sense of hearing detail but at the expense of feeling emotion. They are not expensive and can be returned after a trial.
I am left with a total of one in place on a non user replacable fuse.

I have had better results with the Synergistic Research ECT (electronic circuit transducers) on or near fuses. But more expensive.

Both products have an immediate effect but take about 24 hours to fully settle in.

David Pritchard

Always check with manufacturer! My equipment is not under warranty so I do not worry about that possible issue . Having said that, If I screw up my equipment- I am the one to pay the bill. I believe that the Synergistic Research fuses are safer than the 10 cent fuses. My systems now have a total of 22 SR-Black fuses.

David Pritchard
Oregonpapa:

I very much look forward to your listening experiences with using the RED fuses in your CD player. I found this to be a very pivotal position. My SACD player has one main power fuse and then 5 fuses for the various circuits. I found the main fuse location to be a major change. The 5 rail fuse locations had a much smaller sonic change. One approach would be RED fuse at main fuse and then the WA Quantum chips on the stock rail fuse locations.

Charles1-  I absolutely agree that the SET amplifier magic is only enhanced by the Synergistic Research "RED" fuses. The Emotion type 45 SET amplifier putting out maybe one watt to the Teresonic speakers has an elegance to the sound that was not there with an ordinary fuse. So much more emotionally engaging.
I am not sure where the most efficatious location is for fuse upgrades except to first replace the main fuse of each piece of equipment in the audio chain. I first started with the amp fuse and worked my way "upstream". Even a subwoofer benefits.

Charles1- I did the same thing with my DAC. I ordered the wrong fuses. The great thing with the Synergistic Research dealer organization was the fuse was exchanged for the correct value with no hassle.

Interestingly  to me is the Antelope DAC uses a fuse on both the hot and neutral circuits. It also has its own separate power supply. The "RED" fuses still made a big sonic difference. So despite a very expensive DAC manufacturer ( Antelope) going to the Nth degree for sonic clarity, changing the fuses to  Synergistic Research "RED" made a big improvement.

After putting in a fuse, I normally wait a week of use before changing the fuse direction. I have not heard as big a difference in fuse direction as TGB forum member has. Meaning the new "RED" fuse sounds better in either direction as compared to the stock fuse.
Marqmike:
That was a nice description of the way a new RED fuse breaks in.
knghifi:
I also started at the amplifier when I started replacing fuses, but I have yet to not hear an improvement in a piece of equipment with a RED fuse.

And yes that includes Blue Ray players with replaceable fuses. Dialog becomes more articulate. I wish my Honda radio-CD player had standard fuses so I could replace them!

jazzon the hudson:
Congratulations on your son making all state! My son plays with the  New Mexico All State Symphony Orchestra this Saturday. Does your son have the WA Acoustic Chip on his violin? It certainly changes the sound of acoustic instruments- violin, viola, and acoustic guitar have all been tried at my house. All had a change in sound- facinating to me.
I agree with the Isoclean fuse. There are other fuses that have made a bigger improvement in my systems.

Great news on getting the Afterburner receptacle burned in. For those who have an AudioDharma Cable Cooker, their new adapter allows the ground wire of power cables to be conditioned. The sonic improvement is well worth the cost. It is called theGroundBreaker.

The other device that to me is an extension of the Cable Cooker is Jim Haggerman's Frycorder. This device conditions the house wiring all the way back to the utility transformer. Another sonic improvement.

The Cable Cooker, Frycorder, audiograde A/C receptacles, and audio grade fuses go a long way in removing bottlenecks in the audio chain.
The Frycorder ia available from Jim Hagerman at Hagerman Audio Labs.

haglabs.com

After ordering on line he shipped it quickly. Simple to use. Plug it in via any power cord for three days and that circuit is conditioned. Then remove from circuit. Ater treating, the music has a better flow, less grain, more emotion.

The Frycorder was developed in 2012. the simple manuel even comes with a schematic. Now that is rare in today's world.

Anouncement with a father's pride- I get to hear my son play in the New Mexico All State Orchestra tomorrow morning. No fuse rolling for me this weekend!

David Pritchard
bondmanp:

What Preamp manufacturer are you talking about. I am glad my equipment is not under warranty. I know of no instance of a Synergistic Research fuse failing to blow. In fact they may  blow quicker than the 10 cent fuse.

Twenty one Black fuses in three systems ! I could not be happier. Plus I am no loner afraid to touch my components. I can open the top to a Marantz player faster than a Nascar Pit Crew can change a tire.

I have talked directly with Craig Uthus   of  Eddie Current and Moth amplifiers and he has no problem with me using Synergistic Research fuses.

David Pritchard

    
bondmanp:
Indeed a "bully" did throw your baseball in the lake.
This particular manufacturer states that a fuse can not affect the sound of a system in a positive way. The Black Synergistic Research fuses have improved the sonics in my three systems.
 
1. Art Audio PX-25 amp- Marantz SA11S1 player- custom Horns.
2. Emotion Type 45 tube amp-Antelope DAC-Terasonic speakers.
3. Eddy Current Zana Deux headphone amp- Marantz SA11S2 player- Sennheiser 800 headphones.

In the Terasonic system the original fuses were compared to already burned in Black fuses and both directions were tried. The Black fuses had an immediate improvement in sound - in both the DAC and the amp. 

The Present of PS Audio has stated that aftermarket fuses can have a significant sonic effect on his equipment.

I hope you will try a fuse. I think you will have a satisfying improvement in sound. If not send it back. Listen to the fuse for a 100 hrs. and if your fears about replacing fuses still persists
send it back. 

Do not let the "Bully's win!

Enjoy music.
Enjoy improving your system.

Now for some good info for Mapman. Several days ago I did a Google search for Graphene. I now subscribe to Graphene-Info.com and get frequent E-mails about the latest in the world of Graphene. I think the time was well spent. Graphene's electron density is explained at multiple sites.

Samsung has allocated One Billion Dollars this year to Graphene research and product development. The University Of Manchester- England (where Graphene was isolated) has sixty million invested this year in Graphene research.

I have rather meticulously compared stock fuses to Isotech, Furutech, Synergistic Research-20, Synergistic Research RED, and Synergistic Black fuses in both directions.

I found the sonic changes in rank from best to least to be:
Synergistic Research Black-Best in all ways, Synergistic Red significant improvement, Synergistic -20 some improvement, Isoclean and Furutech mild improvement with careful listening, and in last place stock fuses.

To those who would rather know why one fuse sounds better than another and yet not want to hear the difference so be it. 

To those who are interested in improving the sound of their systems, I hope you will suspend any fears , or prejudices and try the Synergistic Research Black fuses.

David Pritchard


bondmanp:

I do hope you will try a Synergistic Research Black fuse. I have found the improvement to be quite remarkable. Since they come with a 30 day trial, the risk is return postage. Give yourself a present- you are worth it.

David Pritchard
bondmanp:

Do not know your location but I would suggest buying the fuse via E-mail or telephone call to Alfred and Betty Kainz at High-End Electronics, Apple Valley , Calif. He has multiple ads under power cords, and tweaks here at Audiogon. He is a leading Synergistic Research fuse seller and so has a large inventory ready to ship. Normally sends USPS in small box with no shipping charge.
Also he is very understanding about returns. He makes this a no hassle process.

I am a big believer in getting oneself a Birthday Present and seeing or calling one's Mother on that special day in your life!

Wa Quantum Chips: I spent a lot of time and effort trying them on fuses, power cords, interconnects, etc. They do produce a sonic change, bit in my system there was always a sense of information loss. Sort of a more detail but less emotion effect. Other users have had a more positive result. 

Boy the music sounds good at my house these days.

David Pritchard
The Synergistic Research Black fuse is definitely directional. This is coming directly from Synergistic Research in a call I placed. They suggest the flow of current to go From the "S" end to the "R" end.

The Stereo Times article was about the earlier Synergistic Research SR-20 fuse. I have several of those fuses and the Black fuses are much better. I did not find there to be nearly the direction difference with the SR-20 fuse. To me it was a small difference and not huge.

Geoff:
 Actually the Synergistic Research fuse may improve the sound better than no fuse or a piece of straight wire. It's time to get your headphones cryo treated! I had my Sennheiser 650 treated and I like what I hear.

David Pritchard



David Pritchard
Geoff:

Glad to read the headphones and cable have been Cryo treated. James at Stephan Arts Audio makes a nice Sennheiser 600 - 650 headphone cable.

If you at sometime change to the Sennheiser 800 or Audeze headphones, Synergistic Research (SR) now makes a headphone cable utilizing the technology found in their fuse- such as Quantum Tunneling and the use of Graphene. I really like what this SR cable does for the headphone experience. And they come with a 30 day trial.

justtubes2:

My systems do have all Synergistic Research Black fuses and they also have the Synergistic Research Electronic Circuit Transducers (ECT's) in place. 
I do like one ECT at the end of the main power fuse location. At the other fuse locations in the SACD player (a total of six fuses), I did not find adding an ECT improved the sound. Placing the ECT's in a component  (like my SACD player) is by trial and error. The Synergistic Research "how to install instructions " give good suggestions on possible places to try. But not every location will give a benefit. You can certainly overdue it. What I hear with the ECT effect is not the same as Graphene but is helpful.

I think the combined effect on a system that has been optimized with the Black fuses and then fine tuned with the ECT's does sound extremely satisfying.

Oregon papa:

I attended a performance of the  Julliard String Quartet last night. By design it was held in a small performance room that held 125 people. Not by design  160 showed up for the event. People were allowed to sit on the floor along the side walls and even on the floor behind the players! The barrier between the performer and the players was shattered.

It very much reminded me of the effect of the Black fuses.

It was a very special listening experience!

David Pritchard


lak:
The Hagerman Frycorder arrived in about 7 days. The unit is small, well built, and not heavy. The price included shipping.

charles1dad
Thank you for the kind words. 85 top high school students really put out a wonderful big sound. Very adult moment. Then immediate post concert trip to Game Stop to pick up a new video game. Certainly this 21 century is interesting with it's ironies.

On fuse direction:
When putting in a new fuse do a quick comparison and pick a direction. Then wait a week before doing a final fuse direction test. Longer if the system is not played a lot that week- 10 to100 hrs.
Ozzy:
For me the Black fuse in the QOL unit sounded best inserted with the "S" towards the rear of the unit and the printed "R" towards the front of the unit.
Not as big of a change as other locations in most ways, but important in ways difficult to describe but easy to experience.

Remember there is a breakin.Big Time.  I leave the QOL unit on 24/7. It takes a week to stabilize.

David Pritchard






I certainly look forward to almarg's impression of the Synergistic Research Black fuses. I found it to be a fascinating science experiment that then yielded major sonic improvements.

This weekend I had the unusual opportunity to hear the Julliard String Quartet play the same program at two different venues. The second venue was the newly acoustically treated performance hall at the University of Texas at El Paso. This hall reminded me of the sound changes going from a system with stock fuses to a system with Black fuses. 

David Pritchard
bondmanp:

Congratulations on ordering a Synergistic Black fuse. If possible leave it on 24/7 for 3 to 4 days and then do some on and off cycles. Then over the next week let go of listening to this or that change and just enjoy the music. 
with a 30 day trial there is not a need to be in a big rush .

gbmcleod:

In the past I had a PS Audio Power Plant Premier. I find it fascinating that these PS Audio products that regenerate a " better quality power current" respond at all to changes in incoming power cords, what type of footers they are on, and even fuses. But they do!. There is a significant sonic difference in the changes in the RED versus Black fuse.  I am glad you have added to our fuse knowledge data bank about the best sounding fuse in a PS Audio Power Regenerator.

aolmrd1241:

Actually the reported improvement rate using either the Synergistic Research RED or Black fuse is extremely high. In most situations people have found the RED fuse to be a significant improvement over a stock fuse and also an improvement over other aftermarket fuses such as Isoclean, Furutech, etc. I think it is interesting that the Black fuses  in the nine (!) audio devices, I have installed them in have all had a major improvement in the sound. Each component was tried with stock fuse, then RED fuse, and then Black fuse. All fuses were broken in over 100hrs . All fuses were checked  for best insertion direction. I was meticulous in this process. This approach required putting an extra 300 + hours on the  KR PX-25 Tubes which cost about $800.00

The RED fuses is much better than a stock fuse and the Black fuse gives an even greater change. 

With the Synergistic Research 30 day return policy I think this is the most fun and rewarding upgrade an audiophile can do. No matter what the outcome you learn a lot about your system's sound. If you do not like the change you send the fuse back.

David Pritchard

mapman:

I appreciate that you have tried the RED fuse and hopefully have given it 75 to 100 hrs. to settle in. After this time has passed and if you do not think the sonic improvement is worth a $100.00 please send it back to Oregonpappa.

This is the beauty of the Synergistic Research Black and RED fuses. You get a long evaluation period and if you do not find the change worth the money send them back. Returning a non satisfying purchase is liberating. 

 I do think Geoff should order some Synergistic Black fuses and compare this latest technology to the older generation audio fuses and the use of no fuse at all. He is missing out on some new exciting technology.

nyame:

Thank you for the kind words. I have invested a lot of time evaluating the stock, SR-20, RED and now Black fuses in multiple components and systems. The Black fuses certainly have new technology in place that causes a greater positive change than the previous generations of fuses.
Having all the fuses replaced with Black fuses gives an improvement that is greater than a linear improvement.

To me the real important lesions of this thread are:
1. Try a device in your system that allows you to evaluate it for a significant amount of time and allows you to send it back with no "justification" necessary.
2. Become comfortable with critical listening.
3. Become comfortable sending demo's back that do not meet expectations.
4. Evaluate possible system improvements in some sort of systemic approach.
5. Have fun.
6. Allow others to have different opinions.
7. Be respectful of  other posters.

I hope all will take time to enjoy some music this week that not just makes the foot tap but also enriches the soul.

David Pritchard


Oregonpapa:

I am glad the audio grade fuses have made such a dramatic impact on your your system.
  Synergistic Research has not been "selling their souls" to develop these products .Instead they spend a great deal of time with multiple prototypes and multi person listening sessions to get the sonic signature they want. It basically is a product of advanced thinking combined with hard work .

We are the beneficiaries of this process of product development.

knghifi:

I applaud you for taking a break from system evaluation listening. 

geared 4 me:

I have ordered Synergistic Research products from the following with excellent results.
High End Electronics- Alfred and Betty Kainz, Apple Valley, Ca.
Scott Walker Audio, Anaheim, Ca.
David Weinhart Designs, Los Angeles, Ca.
The Cable Company, New Hope, Pen.

All of the above companies have given me excellent service when ordering Synergistic Research products. All have been excellent observing Synergistic Research's return policy!

I look forward to reading about the changes the "Black" fuses make. 
In the three systems I am responsible for maintaining and optimizing, two use "RED" fuses and one uses the original Synergistic Research 20 fuses.

David Pritchard











I have used both Brands: Isoclean and Synergistic Red. I will be interested to hear your comments after 25 hours on the RED. For me they both improved the sound initally but with further break in- the RED continued to improve to a greater degree. Also after some break in time it is worth the effort to reverse the fuse direction to see if there is further improvement.

David Pritchard
fluffers:
Which manufacturer and piece of equipment does not allow the customer to change fuses?

To all readers of this thread. There is a wonderful review of several A/C duplex outlets by Jonathan Lo. Enjoy the Music.com.  January 2014.

Reviewed- Oyaide

I have the Synergistic Research, Furutech, and Oyaide outlets.
Each has different properties that it brings to a system. If buying a first audio grade outlet buy one with a money back return policy. Of course there is an initial change when installed ,but these outlets need 10 to 150 hrs of current running through them to completely open up.

Good listening this weekend!

David Pritchard



r_f_sayles:

Congratulations on installing the fuses. Your description of a freshly installed Black fuse is quite good. If your player is left on 24/7 then by next Saturday I believe you will hear a sound that has even better folw and a sense of bei
A better sense of flow and the music being more "alive".
 
I absolutely agree with you about life being too short. In less time than it takes to post an argument about obtaining some technical measurement,
one can order a Black fuse that has a money back guarantee. High- End Electronics does not charge shipping to the customer. So even if you send it back Insured Priority Mail in a small flat rate box, you are out a maximum of $6.80.

And please remember life is short - My Brother was diagnosed with Acute Monocytic Leukemia on Monday. Risking all of $6.80 to try a piece of equipment that multiple audiophiles have reported on favorably seems like a non issue.

Listening to my system with multiple Black fuses  has given me some real comfort this week. Mozart, Bach, and the serene lute music of John Dowland have been my close companions.

David Pritchard

Gwalt:
Your approach is certainly the best, but it takes time and effort.
The Synergistic Research slow blow fuses are shipping as of today..
I very much look forward to gwalt's observations with the Audio Magic and RED fuses, and also to my reactions comparing these new BLACK fuses to the REDS and the original SR20 fuses.

David Pritchard

Synergistic Research RED fuses started shipping yesterday for slow blow types, and fast blow types start shipping in one week.

David Pritchard
Thank you to for the encouragement for my brother. I posted his condition to gently remind myself and readers that the mortality clock is always ticking.

Try a fuse - no risk involved- if you like the effect your musical enjoyment just increased. If you did not hear a change it was a (at least to me) a fun experiment to perform at no or little expense.There are more important things to ponder than why a fuse construction would make a sonic change.

David Pritchard
Karmapolice:

I have done the RED versus Black fuse orientation in the SACD player-seven fuses and the amp - one fuse. I found the Blackorientation to be the same as the Red. Those fuses were easy for me to get to and so I did the experiment for myself and other fuse users. Of course there could be exceptions. Some of the previous posts have given detailed sonic descriptions of a backward fuse. It is an out of phase- focus sound.

jond:

I look forward to your sonic impressions of a new fuse. You have already taken a step many audiophiles have never done- you removed a fuse!  You also now know how to read the fuse identification information. You are thinking for yourself. What a great experiment awaits you. You can try an audio product for 30 days and if not happy return it easily for your money back.

I congratulate all readers who have tried the Synergistic Research  Red or Black fuses for taking a liberating step forward. I also congratulate all who auditioned the fuses but for whatever reason sent them back. Returning products that do not meet expectations is also liberating!

Enjoy the music.
Enjoy the challenge of improving your music system.

David Pritchard
Jack Shelton- Great trumpet player and a really funny guy on the old television shows. These wonderful fuses and A/C duplexes allow us to hear so much more detail with correct harmonics, it makes the music connect on such a stronger level.

Even with pre instalation burn in, I have found the A/C duplex takes about a week of being used in a system to reach its final sound. Although a lot of work, I compared the Synergistic Research Teslaplex, Oyaide R1, and the Furotech GTX-R A/C, receptacles in my system. My audio circuit has 5 outlets on one line. My final choice has been 4 Synergistic Research Teslaplex outlets and one Furutech GTX-R outlet. more than one Furutech created a too much situation. Like too much salt on a perfect steak.

The Synergistic Research BLACK fuses are supposed to arrive Friday.
It certainly will be interesting and educational comparing their sonic changes with the RED fuse. Synergistic Research (on their Facebook site) says their fuses can be used together in the same componet. So no need to install all BLACK versus all RED fuses.

David Pritchard
Oregonpapa:

As you are using an older Oyaide outlet, I do hope you will consider trying a Synergistic Research Teslaplex SE outlet. Since it comes with a 30 day trial, there is not much to lose. In my system there is a significant sonic change between the Oyaide and Teslaplex. I think the change is worth hearing, and then deciding which works better for your system.

Clifford Brown- great music. First purchased LP 1970 - I liked the cover art so I bought it. The great music was a bonus!

Today I get to hear the wonderful cello player Zuill Bailey  playing live solo Bach. The auditorium only holds 190 poeple.To me this is Jazz composed in the early 1700's. His CD's are moving!

David Pritchard
Oregonpapa:

Absolutely yours is the best approach- one change at a time with time to digest what the change has done. It is easy to rush things and then not be happy with the changes.

Vibraphones- inspired by angels having conversations. Do not forget Gary Burton, and Red Norvo.
The marimba is another wonderful instrument. The warmth of those vibrating blocks of wood sound very good to me.

Hopefully BLACK fuses arrive tomorrow.

David Pritchard
Oregonpapa:
Very nice real time report.

The Synergistic Research products with UEF technology, take 100 hrs for the UEF to synergise with a system. So we should anticipate a longer break in period.

Your report reminds me to install the fuses first on my headphone system and leave it on for 5 days before listening.

Break in is a fascinating and often frustrating process.

This is why the 30 day Synergistic Research return policy is so important. There is for me simply no worry about these fuses. They will go in the system- get a lot of hours on them.Then their direction changed once to see if that is an improvement and then removed and compared to the REDS.

My wife Jean is a world class cook with her Viking oven. I do not open the oven door and take a taste test of her fabulous roast turkey every hour or her indescribably good pecan pie while it is in the oven.

I patiently wait in the kitchen with our two Corggi dogs until it is time to enjoy.
It is fascinating to me that the Synergistic Research Black fuse has had a positive effect on so many different components.

whitestix:

I am glad you tried the Synergistic Research RED fuse. As you did not hear an improvement I hope you were able to send it back for a refund.

I have done a lot of tube rolling and enjoy that part of the hobby. In the 6SL7Gt family, I am sure I have over 10 types. Of those the 1959 Hamburg Germany, Valvo, and the Italian Fivre do something special in the Zana Deux amp. The Tung Sols, National Unions, RCAs, Sylvanias,Brimars, Mullards, CBS, Hyltrons, etc.not as much change. Unlike the Red and Black fuses discussed in this thread, none came with a 30 day trial.

It is interesting that not many people seems to think that tube rolling is a fool's errand . I think rolling tubes , fuses and A/C wall outlets all change the sound in my systems.

I also think Power cords can change the sound of a system especially once one begins evaluating products not of the entry level category.

I find it interesting and sometimes money and time saving to read what others have tried. Especially those who make changes in a systematic way and then have the talent to articulate the sonic changes they experience. None of us have the time to try all the tubes, fuses , or power cords out there.

Because of this thread I have tried the Black fuses and they have improved the sound of my systems. So I reported my results.

At Head-Fi.com I read about 6SL7GT tubes used in the Zana Deux amp. I tried a lot of the tubes and reported what I heard.

I hope you will list the components that did not respond to the SR RED fuse. It is possible you will save other owner's of the same equipment some time and money.


I do not understand when some people experience a different result than others, they feel compelled to cast negativity towards those persons.

Thank you for listing your components that responded to the SR Black fuse. I do think publishing specific component results will be helpful to future readers of this thread.

I am glad you took the effort to change the fuse direction. When the Synergistic Research fuse is not in the optimum direction there is that "sense" of something not being right, for me not being in focus.
I really think to get a emotionally satisfying system it takes a lot of work and not just a big blank checkbook!

I hope you will try a Synergistic Research Black fuse in your system. But you will have to figure out the fuse orientation on your own since you are upside down to us living in the Northern Hemisphere.

Since you are down under- have you tried the Black Discus products from New Zealand. Interesting stuff. They also have a 30 day trial on their products. But no fuses.
