Something For The Fuse Guys ...


There are fuses, and then, there are fuses. 

I'm evaluating some prototype fuses that I received in the mail three days ago. 

Over the past few years, I've used fuses from five different manufacturers. The last three were the Red, Black and Blue fuses from Synergistic Research. Each one incrementally improved the sound of my system. My favorite so far was the SR Blue. 

The prototype fuses being evaluated presently raises the SQ beyond all of the others mentioned above. The major improvement to my ears is better tonal accuracy. Instruments and voices are more life-like. The noise is reduced allowing for a more solid 3-D presentation with the musicians more solidly presented on the sound stage. Overall, more information is fleshed out of CDs and LPs. 

The manufacturer, the price and the name of the prototype fuses will come later. I don't have the information thus far. My understanding is, if all works out, the release date is to be mid-October. 

Stay tuned ...

Fuses are a difficult subject, because there will always be people who don't believe they can make any difference.. And there also be people who don't hear any difference, either because they are less discerning as to the changes in their sound systems or because their systems are not good enough to show any differences. Or, what's even more likely, they have never tried any aftermarket fuses in their systems, but they generally know better about things in this and other subjects and they want to let the world know about it. 
Fuses have occupied me recently - a few months ago, I would have never believed they could change anything in my system, but they did! I have written a little review of a Polish product as compared to SR Blue, I've had it on my computer for a while, wondering where to publish it. I just thought I might publish it here. I liked the Polish fuse much more than the product from SR, but hang on, things are not as obvious as they might seem. 


The Verictum X Fuse happened to massacre the Synergistic Research Blue fuse in my system consisting of a Metronome CD8 S player, a custom-made KT88 amplifier and a set of Franco Serblin Accordo speakers. Its advantage was manifested primarily in the unique culture of the sound versus the vivisection of the SR. There was no jaw dropping when it comes to the bass range. Well, there was the right amount of bass all right, and there was nothing missing in that area. But most of all, the bass came where it should have been and when it should have been. Such a seemingly dry review of the bass is actually a big compliment, because, most of all ,I do appreciate a balanced sound, where no range is emphasised. The area where the X Fuse really stood out right from the start is the midrange. Beautiful vocals (especially male vocals), acoustic instruments, outstanding piano and incredible realism of the double bass, "you can hear the wood" said a friend of mine. I did not get the impression that the X Fuse might adversely affect the treble (as I’ve heard from one user of Polish forum). Maybe people who have relatively warm-sounding amplifiers can get that impression because the X Fuse certainly does not emphasize this range. Strong treble may lead to “a  good first impression”. Strong treble may also be conducive to creating hyper space. However, we should ask ourselves if live music really sounds like that. Listening to live music in a jazz club, for example, we don't see those hectares of space among the musicians, not at least in my experience. What you do get, however, is a coherent, natural sound that will make you abandon whatever you were doing and listen to your favourite music for hours.  I still feel obliged to report an Audio Research user preferred the Blue J

 

Before and during the listening I read everything that had been published about these fuses, both in Poland and abroad (not much there), and one conclusion I drew (apart from the ones I will keep to myself) is that little is said about the significance of the breakin period. When I replaced the fuse in my CD player, the sound was great right away, then the sound improved further. The sound was very good right from the start maybe because the Metronome CD8S is generally a great sorcerer when it comes to colour. But in the case of my amplifier, there were moments when I wanted to return the fuse. My amplifier is hyper-transparent and the addition of X Fuse brought an effect I did not quite like at first. But things improved so much after some 200 hours or so; the artificial hyper detail smoothed out, and there was just beautiful, noble sound, further enhancing the realism of the acoustic instruments. Diana Krall was no longer intrusive with the details of her thorax, but started to sing as your mother might have sounded when she was putting you to sleep. To sum up, I would strongly emphasise the significance of the breakin period, even if it’s not stressed as much as the infamous breakin of Furutech’s products (I did break in Furutech’s rhodium outlet so I know what I’m talking about).

 

Overall, I believe the Synergistic Research Blue might be an excellent product when you are concerned about impact on your treble (in warmer-sounding gear), when you love your soundstage expansive the American way, when you love your bass to impress your guests. But if you want to hear what musical instruments really sound like and your gear is up to the task, I would choose the X Fuse. I would say, X Fuse is Europe, with all its upsides and limitations, and the Blue is America, with all its grandeur and limitations ;)

Disclaimer: I am a customer having recently purchased X Fuse products encouraged by recommendations from some friends of mine. I absolutely have no personal interests in promoting the X Fuse. I am a university teacher in Poland in no way related to the industry. 

I happen to be a member of a Facebook group of audiophiles of the U.S. where people produce a lot of hate speech targeted at Ted, the owner of Synergistic Research. In my review of the X Fuse, I do not mean to discourage people from using his products. I just want to draw your attention to the X Fuse, because I believe it is an absolutely outstanding product. But it’s for experienced audiophiles, who are far over with the audiophile hype, people who want to sit down with a glass of good whiskey and listen to music. But then the discussion is still purely academic, as I believe Vercitum does not do much trading abroad anyway… If you only get a chance to grab it, do! You might find your holy grail!

More X Fuse info,

”As our team at Verictum mainly consists of demanding “long-term” audiophiles, we had personally used higher standard, very good fuses available on the market. However, we had always felt that it was possible to do more in this field, to do it in a different way and obtain even better-quality sound. We decided to investigate this matter further and create a fuse that would be optimal for us. As it eventually appeared, our work let us achieve spectacular results. This is how the first Polish audiophile fuse called X Fuse was created.

X Fuse is a ceramic fuse. The conductor inside is covered with quartz sand that damps its vibrations very well, but its main function is to extinguish the electrical arc which occurs at a short circuit. The conductor of the fuse is made of silver-plated copper. The contacts of the fuse themselves are not nickel-plated, but covered with a thick layer of silver. After many hours of cryogenic freezing adjusted appropriately to X Fuse, fuse contacts are hand-polished using jewelry equipment – each fuse is polished in this way. Next, the contacts are carefully cleaned manually, using an isopropyl alcohol-based cleaning agent. Thanks to this, the purchaser does not additionally have to degrease the surface of fuse contacts. Since the fuse wire itself is protected inside against vibration by quartz, we decided to damp vibrations of the ceramic housing, too, using properly prepared multi-layer covering, to isolate our fuse as effectively as possible from this type of phenomena and unwanted distortion. The whole manual process of preparing one X Fuse lasts almost 60 minutes.

X Fuse fuses are directional. Their directionality must be set after 12 hours of heating by reversing the fuse in a socket. After the direction is set, the fuse is going to “adjust” for about 50 hours.”

Ok, so other than the conductor and silver-plated end caps, it seems you can get at least some of the benefits of the Verictum X Fuse by using standard sand-filled ceramic fuses, polishing the ends using the felt pads on your Dremel tool, maybe adding a bit of contact enhancer to the ends, and damping the body using a method of your choice.  Same old thing, good contact with the holder and damping of both the internal wire and fuse body.  Oyaide has long espoused the benefits of polishing their power connections, both power cord and outlet blades.  For years, I have suggested using sand-filled, ceramic fuses, improving the connection between fuses and standard u-shaped holders by placing a small orthodontic rubber band around the two prongs after the fuse in in-place, and damping the body with a wrap or two of teflon tape.  Folks who like contact enhancers can go that route, Pro Gold for me after trying others.
I have the SR Blue fuses in my new amps and they sound great but I have no idea if that has anything to do with the fuses and probably won't until it comes time to change a fuse.  Hats off to the  Commercial Technology Group (CTG) for coming up with an apparently worthy competitor to $150-$200 fuses for just under 100 bucks.
