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?

David! ...

That was a totally unexpected story regarding Mickey Raphael. He's a great player. The way he bends the notes is very seductive. I've played since I was nine years old, and still can't even come close to mastering the instrument. The harmonica is an easy instrument to learn to play ... and almost impossible to master. I could never figure out how to draw and blow bend until I took a clinic put on by the great Lee Oskar. Lee actually took me aside and took the time to teach me how to get those sharps and flats. It was all about changing my technique from tongue blocking to lip blocking. Who knew?? Talk about sore jaws.

By the way, one of the CD's that I sent you was Robert Bonfiglio's "Live at the Grand Canyon." He's one of the premier harmonica & chromatic players in the world. Another great, and I have a lot of his music on LP, is Charlie McCoy. Another great note bender. 

Sherod ...

Thanks for the input. The Von Gaylord IC's and speaker cables are truly great. I would recommend them to anyone looking to upgrade their cables. I was using some highly regarded cables before, but Ray Leung's Von Gaylord cables are in a league all by themselves. They have brought my system to an entirely new level. 

OP
Many readers of this thread use or are interested in Elrog tubes. They have gone into bankruptcy with their assets  bought by Thomas Mayer  (Germany) and a new named company will restart production. Inquiries should be directed to Thomas Mayer's web site.

 Oregonpapa:
Thank you again for the CD's. Like at a five star drinking establishment your Cd's are sitting on the top shelf in my listening room.

Best wishes for a good week of music listening to all who follow this thread.

I also admit to really liking some of the Daniel Lanois-produced albums from Willie (Teatro) and Emmylou (Wrecking Ball) as well as Robbie Robertson's eponymous solo album....

Too bad about Elrog, but this was an inevitable conclusion to what I've been told was essentially a 100% premature failure rate on their 300b tubes.  I hope the new owner can get the flaws worked out, because they are superb sounding tubes.  The new owner will have a lot of ill will and skepticism to overcome as well as the technical issues, which is not really where you want to be.  It appears that they will accept limited liability for product failures on tubes already in the field.  They will have a tough job getting previous customers to take another chance.   I won't be buying anymore tubes from Elrog.

not to mention Dylan's Oh, Mercy

Installed a black in my Audio Note DAC Kit 1.1. After getting the direction right, I left it on for 4 days to burn in. Didn’t hear any difference.

Just kidding! Instruments sound even more real. Background is blacker. Individual lines are easier to follow. Subtle lyrics are easier to understand. Musical enjoyment went up another notch.

I’m hearing this with my own ears, and it’s still a little hard to believe the difference a tiny fuse can make. I’m loving it, though. It’s like I can go to a concert every day.

Listening to the Oscar Peterson Trio's Night Train right now.

Let the flames begin..

tommylion:
I am glad to hear the Black fuse is making an excellent DAC even better.
You may get whiplash shaking your head at how fast yet clean Oscar is playing!

When does something as trival as changing a fuse become meaningful. I was reminded of that today when listening to Vivaldi's trio sonata op.1 number 12 (RV63) - La folia. Las folia is a simple melody that has been around since the 1400's. It's simplicity lend itself to variations in the melody, loudness, and tempo

OK. so what. It really is not a trio of two viloins and cello as the title suggests, but there is also the continuo of a lute and harpsicord. Before my fuse upgrades, the high pitched plucked lute and harpsichord were burried in the back of the soundstage and added more of an annoying bee buzzing than anything musical.

This piece reminds me of the rock songs that start with a simple melody and eventually end in a furrious climax of interplaying  instruments, speed and volume. The Yardbirds
with Jeff Beck on lead guitar and Jimmy Page on bass guitar springs to my mind. Especially the song "Over, Under, Sideways, Down".

With the Black fuses in place, the bee buzzing becomes instead a furry of individual notes and even the left and right hand parts of the harpsicord can be distinguished.

The improvement in sound was significant and more importantly the emotional communication even more improved.

So give a Synergistic Research Black fuse a try if you want
your music listening to have greater impact and more enjoyable.

David:

Well put. It is the unforced addition of detail that is at the heart of the sonic contribution of the SR Black fuses and outlets....

Andy
David, Oregonpapa, et al,
I'm back with an update now that my SR Black fuse is fully burned-in. I'm using the Black fuse in a high power SS amp and a Red fuse in an ARC CDP.
  First the good; some of you have used the term transformational to describe the effect on sonics and I agree. The soundstage has expanded in width and height, imaging is deep and precise, and a very noticeable lowering of the noise floor.

But and this is a BIG but...my system has gone from smooth, natural sounding digital to hyper-detailed. Let me emphasize that there is no harshness or glare, in fact CD's sound smooth, but music no longer provides an emotional engagement. This is the same effect I experienced when I auditioned the SR Black UEF PC; too much detail from individual instruments in orchestral music. The music does not sound cohesive.
(I've even checked speaker phase and polarity).

My CDP is naturally detailed (ARC CD3 mk II) and my speakers are Gallos with their very resolving tweeter.
So what to do...would a SR Red fuse be a better fit for my system?

BTW, when using the SR Black, music was sounding very two dimensional. After reversing the fuse in the holder, the reward was a glorious soundstage of music.


Maybe you could try the AM Beeswax. I have one in the pre (and SR Blacks in the amps that are now 110 hours burn in), and it is very very good, maybe less demonstrative but more nuanced with more subtlety in the rendering of feeling the "music" in the way you described it. You should try it in the Pre as a kind of rebalancing the sound of your system.
it is just a guess

Hi Lowrider,

If I recall correctly you are using a Sunfire 300 amp, with its "current source" outputs connected to the tweeters, and its "voltage source" outputs connected to the lower frequency drivers. In looking at a rear panel photo of that amp I see that in addition to the mains fuse there is a 5 amp slow blow fuse that is apparently in series with the "current source" output of each channel. I presume that what you replaced with the SR Black is the mains fuse.

Just a guess, but given especially that the amp is probably a dozen or more years old you might try removing the current source fuses that are in series with the tweeters, cleaning their contacts with a good contact cleaner such as one of the Caig products, reinserting and removing them a couple of times (so that the residual cleaner on the fuse might benefit the holder as well), and perhaps even try them in various positions of rotation. (See the comments by Atmasphere that I quoted in this thread on 8-3-2016, on page 49).

Good luck. Best regards,
-- Al

lowrider:

Thank you for a most interesting post. I am glad you auditioned the fuse in both directions.

Too much detail - and the emotional response to this change. This is a fascinating situation. The RED fuse does have less detail and background noise reduction than the Black. I hope you will send the Black fuse back for a refund. Synergistic Research is very serious about wanting you to return the fuse if it does not help.

In my system I preferred a Black fuse in the CD player and in the Tube amp over a Red in the CD player and a Black in the amp.

barbapapa's point idea may well work but it is difficult to return an Audio Magic fuse. It may be your system is now "there" from an emotional satisfaction standpoint. After replacing my fuses I did benefit from a small readjustment of speaker toe in. 

What is the value of the amp fuse? 

David Pritchard
Again with the 30 day return policy. Everyone and his brother has a 30 day return policy. Or a 60 day return policy. Hel-loooo! Why would it be difficult to return an Audio Magic fuse? Doesn’t make sense. Betty seems like a nice person who wouldn't be difficult to deal with. Judge Judy says if it doesn’t make sense it’s not true.
What is the value of the amp fuse?
David, the photo I looked at of the rear panel of the Sunfire 300 amp indicates that the mains fuse is a type MDA-10, which I'm pretty certain is a 10 amp 250 volt 6.3 x 32 mm slow blow fuse.

Regards,
-- Al
 

Fuse amps are SR Black  6x32 mm 10A.  AM Beeswax 1,6 A for the Pre, that will be replaced soon by the new AM Beeswax SHD ordered with another SHD to come for the TT's PSU
SR Black in the DAC.
Sunfire OEM AC Line Fuse is 10 amp / 32 V fast blow. I replaced with SR 10 amp, 250 V fast blow.
Lowrider, is the amp a Sunfire 300, as I was recalling? And does it say "MDA-10" for the mains fuse on the rear panel? Also, of course, a mains fuse would not be rated at 32 volts.

Best regards,
-- Al
 
Also, of course, a mains fuse would not be rated at 32 volts.
P.S: Unless perhaps a previous owner replaced the original fuse with a 32 volt automotive fuse, which might also explain why the fuse that was in there was a fast blow, rather than a slow blow which is what I’m pretty certain an MDA-10 is.

And if a previous owner had indeed replaced an MDA-10 250 volt slow blow fuse with a 32 volt automotive fast blow fuse, I would certainly not find it surprising that changing to a more properly rated fuse would make a transformative difference. And perhaps changing from the SR fast blow you went with to a slow blow would reduce the sonic downsides that you indicated resulted from the change.  As well as minimizing the risk that this expensive fuse will blow prematurely.

Best regards,
-- Al


Yes, Al, it's the Sunfire 300. On the back the Mains fuse says...
Line AC 12VAC, 50/60 Hz. The manual says 10 amp fast blow fuse.
It's quite possible the previous owner or a repair shop installed a 32 volt fuse.

I no longer use the Current Output since I bought Gallo floorstanders which only have one pair of inputs. (The Current fuse is a 5 amp Slow-blo MDL/Q). You have a great memory, as I did previously use a double-run to the speaker's upper and lower drivers.

I now use the Voltage Out since this is the standard output. As you know, the Current Output is for electrostats and tweeters. Due to the higher output resistance, there is less "body" or "slam" to the sound when used as a main output.

My impression is that the Gallo tweeters may be too revealing when using this fuse. It's the same result as when I tried the SR Black PC.
(I have even checked for correct speaker phase and polarity).
lowrider57:

What an interesting amp design from a real audio personality in Bob Carver. I will leave all the engineering to Al. This circuit is way more complicated than my thankfully simple SET amp circuits. 

Being you have an older amp , Al gives  very good advice in cleaning the fuse holders, power cord inlet, speaker ouputs and interconnect inputs. A good "spring cleaning" can be sonically very rewarding.

It sounds like the SR Black line of products are improving detail to a point that is not ideal for your system. That is my emotional response to my son's new 4K TV compared to my Panasonic Plasma TV. Too much detail that for me is distracting. He  loves the added detail.

The Isoclean fuse in my experience has a warmer, less detailed sound than the SR Black. Perhaps this or fuse or other fuses  that have gold in them would give you warmth but with less grain than the stock fuse.   

You may want to try one of the fuses offered by Music Direct. They are a fine company that has always honored their return policy.

Before ordering fuses from VH Audio or Parts Connexion be sure they accept fuses returns.

Audio Magic fuses are not normally returnable for a cash refund. At best one may be allowed store credit towards a future purchase.

When buying any product make sure to understand exactly what the terms of return are. 

Audio system enhancement and audio listening should be a rewarding and fun endeavor. I plan on having a very fun and rewarding session latter today.

David Pritchard
Lowrider & David, thanks for the additional comments. Lowrider, yes, in the rear panel photos of the amp that I’ve looked at via Google Images it says "120VAC 50/60 Hz" immediately under the fuseholder, as you indicated. But further down and a bit to the right, just under where the power cord emerges from the panel, the photos I’ve looked at say something like "for continued fire protection use original fuse type and rating only of MDA-10."

Here is a datasheet for the MDA series of fuses. Note in its title and in the first line under "description" the words "time delay," which would certainly seem to correspond to slow blow. Also, Digikey’s listing of that fuse, shown here, states "response time: slow." And the "nominal melting" spec of 1491.3 amps squared-seconds for the MDA-10 is well into the "slow" category, for a 10 amp fuse.

So if that same wording appears on the rear of your amp I would have a good deal of concern that an expensive fuse described as fast blow might not last too long in that amp, regardless of what the manual says.

Regarding Bob Carver, he certainly was (and still is) quite an innovative designer. For a goodly number of years starting around 1982 I used his model M400t amplifier, a 200 watt/channel amp in the form of a cube measuring just a bit more than 7 inches on a side(!). It was designed to emulate the "transfer function" of the very highly regarded Mark Levinson ML-2, a pure class A design rated at 25 watts or so into 8 ohms but capable of providing enormous amounts of current into low impedances. Although Mr. Carver pretty much admitted in a TAS interview a few years ago that as might be expected the design succeeded in emulating the ML-2 just to a loose approximation at best, it provided me with very satisfactory results for quite a few years, until I eventually transitioned to tubes. And it seemed every bit as powerful as its rating would suggest, at least when used in conjunction with the easy to drive speakers I was using at the time.

Prior to that time, though, I very briefly owned a predecessor model, designated as the M400a if I recall correctly, which was not designed to emulate anything and provided sonics that were quite disappointing. But the M400t was a "night and day" improvement on that earlier effort, and he presumably carried the benefits of those experiences forward into his Sunfire years.

Best regards,
-- Al

Al we share a common link in owning Carver products. In medical school, I "upgraded" to a used Bob Carver Phase Linear 700 amp. Well it certainly did make my Klipsch Cornwalls play LOUD ! I am not sure about all of his design skills, but he was one of the best self promoters out there. It would be interesting to tally how many companies he has started and then folded.

I think the ringing in my ears finally subsided when I bought my first
SET amp (Art Audio PX-25) in 2008! It took me a long time to overcome the audio dealers party line of the 1970's - bigger amps give bigger sound, no matter what the efficiency or type of speaker is used.

Thank goodness for the internet where approaches to a satisfying musical system can be discussed from multiple points of view.

Since this amp under discussion is a Carver product,
 is there a fuse made that has a built in fire extinguisher? 

A few of the Phase Linear 700 amplifiers could have used a fuse with that feature !

David Pritchard
Yes, David, as you no doubt realize Carver's 1970s Phase Linear Corporation has often been referred to as "Flame Linear."  But believe it or not the Carver Corporation M400t I mentioned that I purchased around 1982 is still going strong in the home of a relative.

The predecessor M400a model that I mentioned I previously very briefly owned (I couldn't wait to get rid of it), did often manifest a very prominent glare in the treble region, among other sonic shortcomings.  Which I can imagine would have induced ringing in the ears of many listeners.  That and most of its other shortcomings, though, were completely eliminated in the M400t.  At least, as I said, when it was used with easy to drive speakers.

Regards,
-- Al

I don't think so, but there is one that comes with a 30 day free psychologist.

"further down and a bit to the right, just under where the power cord emerges from the panel, the photos I’ve looked at say something like "for continued fire protection use original fuse type and rating only of MDA-10."
Al, I appreciate your research into the correct type of fuse. I didn't see the instruction on the back of the amp since I have a conduit on that shelf to separate cables.

 My first move will be to pick up some Bussman MDA-10 fuses and return the amp to baseline. Thanks again for the info.

BTW, all contacts on my amp were cleaned not very long ago, and I will clean the fuse holder.

Lowrider, it looks like the MDA-10 may have been superseded by the MDA-10-R, which is very similar except that it is lead-free and complies with the European RoHS (Restriction of Hazardous Substances) requirements.

As you may have noticed at the link I provided for the MDA-10 Digikey has no stock under that part number, but that page refers to the MDA-10-R as being an RoHS compliant replacement, and the technical specs on the two parts look very similar. The page for the MDA-10-R shows thousands as being in stock, for $1.58 each in small quantities.

Digikey is a distributor of electronic parts, mainly serving industry. But they have no minimum purchase requirement for most items (apparently including this fuse, since a quantity 1 price is indicated for it), and every transaction I have had with them over the years has been prompt and flawless.

Best regards,
-- Al

It sounds like the SR Black line of products are improving detail to a point that is not ideal for your system. That is my emotional response to my son's new 4K TV compared to my Panasonic Plasma TV. Too much detail that for me is distracting. He  loves the added detail.
David, I feel the same way regarding video.
As stated earlier, I got the same highly-detailed sonics when using the SR Black power cord. But the lush, sumptuous sound of the SR is addicting.
Regarding the Isoclean fuse, there's a very good review written by Albert Porter, although he's probably moved on to some other tweak by now.
A friendly reminder to all that replace fuses in their equipment to remember to turn off the equipment before replacing the fuse. I do not know why but changing the fuse recently with a different fuse resulted in the new fuse blowing. I would guess it was a current in rush situation but on a solid state piece of equipment. So turn off equipment - replace fuse - turn on equipment.

Today I am again listening to Vivaldi: "The Four Seasons" . The most recorded piece of classical music. Hundreds of versions are available.

Giuliano Carmignola lead solo violin with the Venice Baroque "Orchestra". On the Sony label. Why this version?  Vivaldi was a leading experimenter with getting more than pretty notes from the violin. This is not the beautiful but always proper music of Mozart, but fiery, passionate, expressive music.

While listening to  Carmignola's version, I was reminded of early Jimi Hendrix. Creating soaring, complex sounds with a minimum of effect pedals,  Hendrix instead used  extreme settings on the Fender guitar and Marshall amp. Likewise Carmignola creates a multitude of expressive sounds but is doing so on an acoustic instrument using creative bowing and fingering techniques.

On  Vivaldi's work, the Synergistic Black fuses in the system are allowing me to hear the individual instruments in a very moving way. I can focus in on an individual supporting instrument or simply listen to the combined sound of all the players. This ability to listen to one or all the musicians is one of the reasons I go to hear live music. But live I have my eyes to assist my ears in determining who is playing what part. At home the Black fuses are replacing my eyes in enhancing the listening of music.

A great weekend for music.

sent this email to a friend about my first experience with magnets instead of over sized fuses used at the time.   written 3/9/08

Pete, Had the magnets on the board when Darrell did all the upgrades and mods to the amps..You have the pictures. Tonight was WOW replaced the mains fuse..and its all a lot better. The main vocals are now at the top of my SP4 rack and the balance and pressure in the room is all most exact left to right. More detail and harmony in the highs. Things I thought were to loud on the same disc ..can just sail thru.don't reach for the volume and jump up to tweak the balance...and shits everywhere..more depth and I can hear further into the silence at the end of the disc being played and in between cuts as they fade from one to another. The transition is quiet and seamless. Cool..Tom

So, technically, why do you think magnets sounded better than oversized fuses?

cheers

I think besides the increase in conductive surface area a magnet helps focus the electron field so it is less random and becomes more organized. Like the electrons that leave a cathode in a picture tube they may leave at different angles but can be adjusted with a magnet or as an electron lens. The magnet may bend the electrons towards a common point.

For me magnets also appear to focus vibrational energy over a given surface even one that is considered a non traditional conductor. They make for a more dynamic and organised presentation. Results in better sound.

Tom...

remember the use of magnets negate the safety aspect of the use of a fuse. Magnets were used for audio testing and not for any consumer products.

What difference could bending the electrons or electron field make since the electrons are barely moving through the wire? Besides electrons are moving back and forth in an AC circuit, like in the mains fuse situation.

Tom also wrote,

It sounds like you are saying vibrational energy is good and therefore the more the better. Why not just employ a shaker machine? That would produce all the vibrational energy you could desire. I’m not sure I go along with you that vibrational energy is subject to magnetism. Wouldn’t the "vibrational energy" have to be uh, magnetic?

cheers


When the electrons direction are bent by the magnetic field then they have a shorter path to travel across the conductor.

Some electron microscopes use a magnetic lens to focus electrons.

Vibration can generate electricity that can react to the magnetic field.

Musical instruments generate large amounts of vibration..hear that.

Tom: "When the electrons direction are bent by the magnetic field then they have a shorter path to travel across the conductor."

The electrons are not the signal. Why would a shorter path for electrons improve the sound. Besides the electrons are moving back and forth as I already said. Their effective path distance is zero.

Tom: "Some electron microscopes use a magnetic lens to focus electrons."

But electric microscopes are not audio cables. How would focusing electrons change the sound, assuming for the moment magnets do focus electrons. The electrons are moving only a cm/ minute.

Tom: "Vibration can generate electricity that can react to the magnetic field."

Really? Example?

Tom: "Musical instruments generate large amounts of vibration..hear that."

Are you saying musical instruments are creating electricity?

Better advice is to unplug equipment before changing the fuse.  Many pieces have a constant draw of power to keep some circuitry "warmed up".
dbarger:

Thank you for the reminder that to insure that a component has no active circuits,  it must be unplugged and not just turned off. Hey that's just what they always tell me to do at the computer "help" site after putting me on hold for 30 minutes!

Well the replacement Black fuse is in place and now has 75 hours on it. What a nice improvement over the back up Isoclean fuse. I am listening to Harp music to unwind after a stressful day. The shimmering harmonics of the plucked strings resonating with the body of the harp is most relaxing.

The plucked leading edge of each note is sharp and forceful, and then the relaxing full bodied complex decay of the note takes place. All this is occurring  with a jet black background and with a soundstage depth of a medium sized concert hall. Really quite remarkable.

An upgraded audio fuse has made this long stressful very hot day turn into a most satisfying and reinvigorating music listening night.

Way off topic (though the goodness of the SR Black fuses and outlets shine on through everything in the chain), but this afternoon I got Tidal working through my Bryston BDP-2 music player and it sounds extraordinarily good using multimode duplex fiber to isolate the Ethernet ground noise from the network. Next up is figuring out how to incorporate the Roon meta-data service into the picture.

Keeps my retired-ass 61 year old mind working, so I've got that going for me...

andynotadam:

Actually  I think your post is on topic because the improvement to a system that uses the Synergistic Black fuses and Black wall outlets allows streaming sources to really sound wonderful. The enhanced spacial information, the blacker background, and overall more relaxed sound makes streaming a much more satisfying experience than before I installed the Black fuses and Black outlets.

Congratulations on getting Tidal working and best wishes on getting it tweaked to reach it's maximum utility.

His or yours?
I just read that on the PS Audio forum. It is a comparo of different fuses. It is interesting : 
"capt mark said
I just finished testing some fuses I my DS. I had SR Reds in my DS and amps, and wanted to try the ones Odd had been discussing. I first tried the SR Black, and it was quite a bit better in my system. It had more detail and was smoother overall, a nice upgrade from the Red. Next came the Audio Horizon Platinum. It was very much like the Black, and I had to switch back and forth to pick out the differences in these two. The AH had just a tad more detail, and the bass was a little tighter. I liked both fuses and could live with either one. Then came the Audio Magic SHD with it’s magic beeswax. This one is something special. More detail and smoother than the other two, but the main thing is the amount of space and air around the instruments and vocals. It presents a more lifelike sound stage with more width and especially depth. I will leave the AM fuse in my DS, and I have ordered 2 more for my amps. These results are, of course, in my system, and YMMV. I just wanted to pass along the info for those who are interested.
Mark"

barbapapa:

Thank you for the interesting report on the PS Audio Forum by Mark. This is a good data point for those interested in the Audio Magic fuses. I hear significant improvements using the latest generation of fuses as compared to the fuses I bought in 2012. Likewise I hear major improvements using  the wall outlets currently available versus those available in 2012. 

Certainly a wonderful time to be a music lover and an audiophile.

This afternoon was spent enjoying beautiful music streamed to the Terasonic speakers after being amplified by about 1/2 watt courtesy of the Type 45 tube SET amp.  SET amps certainly do respond to fuse and wall outlet upgrades.

David Pritchard
Also, too, way off topic, but Tidal sounds very good though my setup--if a bit more two dimensional than playing CDs ripped to AIFF via iTunes. Tidal uses FLAC. Background is totally silent. Reminds me of hearing familiar music rendered at the movie theater. Very full and possessing a huge soundstage, but again, a things are a bit two dimensional. 

I've had quite the time playing "Stump Tidal." It led to a Savoy Brown session last night and a Traffic session tonight....
