The new Synergistic Research BLUE fuses ....
New SR BLUE fuse thread ...
I’ve replaced all 5 of the SR BLACK fuses in my system with the new SR BLUE fuses. Cold, out of the box, the BLUE fuses stomped the fully broken-in SR BLACKS in a big way. As good as the SR BLACK fuses were/are, especially in comparison with the SR RED fuses, SR has found another break-through in fuses.
1. Musicality ... The system is totally seamless at this point. Its as if there is no system in the room, only a wall to wall, front to back and floor to ceiling music presentation with true to life tonality from the various instruments.
2. Extension ... I’ve seemed to gain about an octave in low bass response. This has the effect of putting more meat on the bones of the instruments. Highs are very extended, breathing new life into my magic percussion recordings. Vibes, chimes, bells, and triangles positioned in the rear of the orchestra all have improved. I’ve experienced no roll-off of the highs what so ever with the new BLUE fuses. Just a more relaxed natural presentation.
3. Dynamics ... This is a huge improvement over the BLACK fuses. Piano and vibes fans ... this is fantastic.
I have a Japanese audiophile CD of Flamenco music ... the foot stomps on the stage, the hand clapping and the castanets are present like never before. Want to hear natural sounding castanets? Get the BLUE fuses.
4. Mid range ... Ha! Put on your favorite Ben Webster album ... and a pair of adult diapers. Play Chris Connor singing "All About Ronnie," its to die for.
Quick .... someone here HAS to buy this double album. Its a bargain at this price. Audiophile sound, excellent performance by the one and only Chris Connor. Yes, its mono ... but so what? Its so good you won’t miss the stereo effects. If you’re the lucky person who scores this album, please post your results here.

Overall impressions:
Where the RED fuses took about 20 hours to sound their best, and the BLACK fuses took upwards of 200 hours of total break-in, the BLUE fuses sounded really good right out of the box ... and that’s without doing anything about proper directional positioning. Not that the BLUE fuses don’t need breaking in, they do. The improvement continues through week three. Its a gradual break-in thing where each listening session is better than the last.
Everything I described above continues to break new ground in my system as the fuses continue breaking in. Quite honestly, I find it difficult to tear myself away from the system in order to get things done. Its truly been transformed into a magical music machine. With the expenditure of $150.00 and a 30 day return policy there’s really nothing to lose. In my system, its like upgrading to a better pre amp, amp, CD player or phono stage. Highly recommended.
Kudos to Ted Denney and the entire staff at SR. Amazing stuff, guys. :-)

Edsky, What you experienced also happened in my amplifier upon installing the fuse. I listened for 1 or 2 hours and let it as is. The next day, I didn’t waste time and just reversed the fuse in the fuse holder and everything went just perfect. I guess it is because I reversed it but I wasn’t sure since that I also leave my amplifier (and whole setup) on 24/7. I also noticed that before my system could be on the edgy side since my speakers (Totem Mani-2 Signature) requires very good electronics to avoid that problem but after two weeks of "24/7 on" and about 4 hours of actual listening per day, the edginess seems to be gone. and this is with only 1 fuse. I have two amp boards with 2 fuses each, and the tone board that has 3. I am very curious now to know what would be the improvements if I change them all. My amplifier is vintage so the actual fuses are, most likely, vintage as well. So far, so good. |
edsky ... Try reversing the direction of the fuse and see if the bass improves. If that was the problem, the imaging will be more defined by switching the fuse direction as well. When the fuse is in the wrong direction, the system will sound a bit out of phase and just not right. Please report back with your results. Thanks ... Frank |
Thanks to everyone for posting their experiences with the SR blue fuses. I just installed one into my amplifier four days ago and I was blown away by the improvements in clarity and realism, which became apparent after just a few hours in my system. One thing I've noticed though is that the mid-bass is sounding a bit soggy or slightly muddy. I hadn't noticed this before installing the fuse, but to be honest, perhaps it was there and I'm just listening now with a more critical ear. My questions are as follows: 1. Could this issue I'm picking up with the mid-bass be related to the fuse requiring more burn-in time? 2. I leave my amplifier on 24/7. Would the time that my amplifier is on but not play music contribute to burn-in time? |
Late to the game but last Friday I received my Synergistic Quantum Blue fuse. I only ordered the main fuse to see what changes it would bring (or not) for my Yamaha CA-1000... And changes it brought. Compared to my Audio Link fuses (local brand in Qc similar to HiFi Tuning) which affected to tonality of the amplifier and made it more lean sounding, the blue fuse did not change the tonality of the CA-1000 at all. It still is a sweet and warm sounding amplifier. There is an increase in bass weight and instruments are even more life like. I could also perceive a decrease in noise during silent passages. There is more fullness to the music reminding me of my past Mc setup. I noticed also that the highs are more natural, a bit less strident. Essentially, it does not remove anything of the good from the amplifier, but only add up some even better qualities. This is not the night and day difference I was expecting/hoping but since I only changed one, this is normal I think. Still, the improvements it brings are appreciated. I think I will slowly change all the 7 remaining fuses, a 4 set for the pre-amp and a 3 set for the tone control board. I plan to keep my amplifier for a while (say, I will give it to my son in 10 years once he reaches his teen.) so I am fine tuning it up. |
Well, I finally ordered a blue fuse for my amplifier (Yamaha CA-1000). I opted first for the most important one, which is the one on the amplifier portion. If the results are good enough, I will probably buy a set of 4 more fuses for the pre-amplifier twin boards. Cross fingers.. I will report later after I receive and try it out. |
I’ve been around here off and on for a number of years and never thought about the fuses in gear. Just got my Blue fuse last night in the mail. It replaced the stock fuse of my Krell S-300i integrated mains. This is the first fuse I ever purchased. When I bought the Krell, it came with an SR 20 fuse installed. I listened for a few weeks with the SR 20 installed in the integrated, and then tried the stock fuse just to hear the difference between it and the SR20. The SR20 was slightly better than the stock fuse, although I thought the stock fuse had slightly better clarity. Here is the change that installing the SR Blue in the Krell has brought as it settles in: 1. I understand what others have posted who used the descriptor for the sound of the speakers now as "continuousness" (which is actually a word); there is a coherency to the sound that is very noticeable over and above the way my Klipsch speakers have sounded on the same recording before 2. There is an added density to the music (more fullness/ weight) to the sound of the speakers 3. There are definitely more details than before that stand out on recordings I have listened to many many times 4. There is more depth to the sound of the speakers 5. I hear bass notes I did not notice before on very familiar recordings 6. The soundstage is widening 7. The level of sound quality of the speakers has gone up (many audiophiles are chasing improved sound quality) caveats: 1. I have not reinstalled the fuse in a different direction yet 2. More time for the fuse to settle in (break in/ burn in - whatever you may call it)-- time is needed that will take days to complete The problem is that many of the people in this voluminous thread who criticize the idea of the SR Blue fuse being worth that kind of money (149), are thinking in terms of a traditional fuse (a small inexpensive thing to manufacture that traditionally is worth pennies on the dollar), which they are. These critics don’t think of the possibility that a fuse could have the effect in the audio chain that other gear could have; it’s just a fuse. But some of them would pay the price of the SR Blue (and more) for a power cord, or interconnects or a set of tubes, or a phono cartridge. When you hear the effect of installing the SR Blue, that’s when the value comes in to play. In my opinion, this little tiny fuse has the value it does because it can achieve the same or better affect as changing out a power cord, interconnects, a different set of tubes, or a phono cartridge. The value of this relatively expensive Blue fuse is in the "cause and effect." From my brief experience, with the SR 20, stock fuse, and now the SR Blue, it really does have the effect of a power cord or other more expensive changes you can make to your system. Could it be sold for less? I don’t know, but it works. Until you put the fuse in your gear and listen you have no chance to know. The only thing that beats a fail is a try. |

I have done just that and was glad that I upgrade to the Blue fuse. Order one and give it a try. After installing you should hear a difference after 24 hours and the final break in will occur on day 10. This still gives you 20 days to decide if you like the sound. My Blue fuse stayed in the sub. Any doubts send it back for a refund. David Pritchard |
Discopants, are you sure there is replaceable fuse inside Lyngdorf TDAI unit? I was not able to identify any fuse inside TDAI 2170. I have TDAI 3400 now, which I haven’t tried to open yet, but from online hi-res photos of inside of the unit I was not able to locate any standard fuse again. If there is one, where exactly is it located? |
@parbellum, The first fuse I ever tried was the HiFi Tuning Silver Stars. Experimenting with a different fuse made it plain to me that the Silver Stars had lots of leading edge, detail, and attack, but at the expense of body, tone and fullness. If your Audio Link fuses are like that, then that would explain what you're hearing. Every fuse sounds different, even those of different tiers from the same make. It's funny, and reassuring, that you found yourself having to turn the volume down a bit as I had to as well. When I reported that minor finding, boy did I get a lot of blowback, but now it's pretty much a common thing. I haven't tried the SR fuses yet either, but if you do what I did and try other brands, the total will add up to the cost of a Blue Fuse, or thereabouts. All I can say is to experiment with fuses like you would with cables until you arrive at what sounds best to your ears in your system. Happy hunting. 🔍 All the best, Nonoise |
parabellum: It is wonderful you are willing to experiment to obtain superior sound. I have tried some of the HiFi Tuning fuses in the past, and I do think the Synergistic Research Blue fuses are much better. I think you will hear more music with less fatigue. They will sound good after 24 hours, very good at three days and will be fully settled in on day 10. That then gives you 20 days of listening to decide if they stay in your system. Have fun. David Pritchard |
davidpritchard: Thanks, sure I will. I find my audiophile grade fuses to add too much clarity to a point where I find it ear fatiguing over an extended period. It brings a lot of other good things on the other hand as the system seems quicker with tighter bass. As some others have reported, I noticed too that I need to dial less the volume knob to get the same sound output from my speakers. My fuses are a brand called Audio Link from Planabox, and they are similar to HiFi Tuning per what I was told. So if people report giant leap in performance between the HiFi Tuning and the SR Blue, then I am even more curious to try it out. discopants: Very good and objective write up. I have noticed too often the tech crowd / engineers are the ones who are the most skeptical. They always have the same rhetoric "cables conducts the same electricity so they will all sound the same". When one curious audiophile comes in with claims that cables, fuses, tweaks, etc. improves the sound, they are among the firsts to naysay. I agree with them that the basic principle to carry electricity / signal apply to all electronics but there is just much more than just that and that I cannot understand myself. Only my ears tells me I am no fool. I recently had my CA-1000 modified to remove that '74 original lamp cord and had a proper socket installed so that I can use whatever cable I want, and as soon as I plugged a better power cable, things only got better. I can understand that if you feed an amplifier with better juice, it will have more air to breath. But how and why it affects the sound? I have no idea. Same thing for my Bryston BDA-3. I started with the supplied stock cord and hit play to have a listen. My reaction? Meh.. That's it?? After a few hours, I decided to plug a Shunyata Black Mamba HC/CX and my god what a difference. I cannot explain rationally why it works, but it does. And in the end this is what we all want I think. So for the blue fuse, I just hope they won't be too bright or add too much clarity or kill the bass. |
I’d just like to say thanks to the folks on this thread who have tried the blue fuse and posted your experiences. Ive actually just finished reading the whole thread and its a surreal one to say the least. You definately couldn’t make this up. I was very sceptical initially about the superlatives being used by the few who took the opportunity to try these fuses early. Im naturally sceptical but Thankfully 😅 im also experimental, so i wanted at least to try them. i concur that these are the best tweak on a value for money basis that ive tried to date. I’m not finished quite yet though. The technology in these fuses is something special. I dont have any real understanding of it (and may not even be fully understood by the makers). What is clear though is that it is blatantly inconcievable to the classically trained electronics engineers that have frequented these pages preaching “snake oil”. I feel sorry for the few one here who I have no doubts preach because they are duty bound to protect the less knowledgable consumers amongst us. Their intentions are good, its a shame that some of them havent actually tried the product as they are almost certainly missing out or having to pay a lot more money for a system as musical as mine is now. i will be trying these fuses inside my Lyngdorf TDAI amp at some point |
discopants: A very nice write up of what the Synergistic Research Blue Fuse does for a system. The music is simply more enjoyable to listen to. parabellum: I do hope you will try the Blue Fuse as I think you will be very happy with the improvement you hear. And if for whatever reason you are not happy with the fuse send it back. David Pritchard |

/discopants I am glad to know that based on your experience that the tones are not affected. I like the warm character of my CA-1000 and I wish it is not affected too much. The added clarity and a deeper bass seem a perfect blend in what I am looking for. I think I will buy one, the 30 days trial is a good incentive. |
I personally dont find the blue fuses to add a tone to the sound when i upgraded the plug socket ones. My system is Solid state. My ears detected a marked lowering of noise floor, so details came through that i could not discern on tracks im very familiar with. There is a clarity to the system now as you remarked that makes the music sound much more realistic to live music. Improvements to soundstage imaging. Bass seems deeper. Percussion in particular sounds markedly better thats all the way through high hats, bells chimes, bongos, rim shots, brushed, snares, rolls and bass drums. The sustain on strings and chimes just seems to go on forever. Brass sounds sublime as does voice. i went from 2nd hand SR20s to the blues , the leap in performance is remarkable. i would say take them up on the 30 day trial , what have you got to lose and pay attention to direction. |
I recently had my Yamaha CA-1000 amplifier installed audiophile grade fuses all over (2 + 2 on preamp boards, 3 on tone control board and 1 for amp section) and there was an obvious change right away. At first I was wowed by the clarity and tighter bass, but now the amplifier sounds more lean. Tonight I decided to just change the amp fuse for the stock one and the bass came back but with a slightly darker sound. Would the blue fuse bring the best of both worlds? I like a warmer sound to match my Bryston gear. If for one fuse, I may just buy one to try out and see for myself but that would be nice if someone can chime in. |
Quick,question. i bought 3 13 amp blue fuses on a bit of a deal here. I put one in the plug of my mains block, one in the plug of the amp , which is also my source (spotify stream) and one in my sibwoofer power lead. Ive got to say im really blown away by the system performance gain. Simply stunning sound now, very good value for money in my system. I would say at least equal to going up a tier in speaker. now im very curious about changing the internal fuses in my sobwoofer and amplifier... i think 1 fuse in the amp IEC and 2 fuses inside the amplifier. From experience , how much better could it sound if I replaced these fuses with blues from stock supplied fuses right now , bearing in mind i already have 2 blue 13amp fuses upstream from any internal fuse? Will it be another similar jump to my first 3 fuses or a fraction of that and if its a fraction best guess...... answers on a post card. oh my mains cable and extension block did have sr20 quantum fuses before i went blue. thanks in advance Disco. |
I did not mean harm the operation of the equipment. I meant lessening the audio sound quality, just as the Shakti Stones did. The NDM is certainly inexpensive to try. Unfortunately, the Shakti Stones also did no favors to my friends Robert or Grovers systems. Robert and Frank are on the same page as to the fantastic benefit the Hallographs make. |
@fleschler - New Dark Matter NDM improves SNR. If you consider that “harm” this product is definitely not for you. Why would you even make such a statement? In fact, I will not sell to you. Too much angst and trepidation and drama. And you already gave us your Shakti Stone sob story. 😥 No matter how great a product is you don’t have to look too far to find somebody somewhere who swears he can’t hear it or that it hurts the sound. |
Ben Piazza came over and could not get better sound out of his Shakti Stones in my system. They are system dependent. But two pairs of his Hallographs are more important than SR fuses and HFTs. My speakers really need the Hallographs. Another big loser for my system were the Magico Qpods under five pieces of my equipment. Awful effect of loss of PRAT and dulling the sound. Supposedly excellent for Magico speakers. The kept all my Stillpoints instead. |
There are many perfectly valid reasons why some people don’t have any luck with certain tweaks. It’s been that way even since audiophiles chimed first in on power cords, Mpingo discs, Shakti Stones, the Green Pen, the Tice Clock, Silver Rainbow Foil and Schumann frequency generators, to name a few. However, by and large most of the testimony is positive, so I suggest we call the negative results OUTLIERS. And throw them away. The preponderance of the evidence, folks, you know, with more than 80,000 aftermarket fuses sold since they were first introduced, most of which these days are Synergistic Blue Fuses, is that the SR Blue Fuse is both effective and directional. Oh, by the way, when multiple fuses are involved the only rational way to determine that all fuses are in the correct direction is to change the fuses one at a time, listen and evaluate as you go. There is no way to tell by looking at the fuses which way they should go. We can review the reasons why some people don’t get the results they were expecting for fuses or anything else any time anyone wishes. |
Thanks for the suggestion. I tried that during the A/B process. One direct is a little better but not significantly. Once I settled on a direction, I put 5 hours on them and as I stated earlier, fatigueing was the best way to describe the listening. Maybe you have to earn the burn in process and deal with it. next time I open the amp up, I will get my DVM out and test fuse holder to the line on the plug to confirm true direction. Regards |
MEM2112 Please try inserting fuses in the opposite direction to what you had initially. Yes sounds crazy but no more crazy than the fact that a fuse can have an effect on sq to begin with! And by your post you can at least concur it did indeed effect the sq big time, just not how you hoped! So while you have them please just try again as I had EXACTLY the same experience in a DAC a couple of years back. Good luck |
