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. :-)

Frank

PS: If you try the SR BLUE fuses, please post your results here. Seems the naysayers, the Debbie Downers and Negative Nellie’s have hijacked the original RED fuse thread. A pox on their houses and their Pioneer receivers.

Why is Audiogon full of SO many angry people of late?
Never used to be this way, sure there were always differences of opinion, thats part of the appeal but downright rudeness and obnoxious? The rise of the internet age has unfortunately resulted in way too many "keyboard warriors" who really have nothing much better to do.

So sad......
I know some members are not going to want to hear this at all and I truly cannot explain it as pure science says it should not really occur but.....
I obtained a sr black fuse from a member here who had upgraded to a blue fuse.
Very decent price and if I heard no difference I could just send it back to him.
So it arrived Monday late post and I fitted it to the PS of my Exogal Comet Plus and sat back and listened. Hmm, I thought, might be something there but not much.
So I reported back my findings and he suggested I change the direction of the fuse...yeah right I thought!
However a short task so no big deal and sat back and listened again today.
WTH? No way could just changing the direction make THAT much difference.
Checked made sure nobody had slipped some new components in while I was not looking, unfortunately not so only conclusion is that fuse direction IS a big deal after all.
The change?
Deeper tighter bass, more pronounced soundstage, much better definition on strings...just for starters.
Yes there will be naysayers and I was a complete unbeliever on tweaks up to just a year or so ago.
But now? I'm sold.
Blue fuses next please!
@hifiman5 
Mucho gracias for the warm welcome to this most esteemed club! The ears have it!
I know what I hear and although I truly would like to know the exact how and why, to heck with it tbh, it works for me and that is really all that matters.
And its not like I am trying to justify an outrageous expense.....I mean $50 is what I paid, a nights beer and smoke money for some.

@marqmike 
Yes Al is truly a gent and has imparted many words of wisdom on my behalf.

And as to the naysayers?
Honestly their loss if they truly cannot hear a difference and again that is up to them and no hard feelings on,my side at all and I wish every one of them well.
But PLEASE do not presume to tell me that I cannot be hearing what I know I am hearing!
Charles
You are absolutely correct and I have no intention or interest in arguing with anybody here at all.
Just sharing my very positive experience.
I am not sure if it is a case of some cannot hear or just will not hear any difference.
As an engineer if I hunkered down, researched and put this rusty grey matter to use I likely could come up with a number of reasons based in science and theory of just why a change of fuse or direction of fuse could NEVER cause an audible change.
But the facts remain that they did, in my system to my ears and that is it for me.
@ps 
My experience earlier this year was to replace the fuses in my BAT power amp with a pair of sr black and there was an immediate and definite difference, much tighter bass, wider soundstage, lower noise floor, no I would not have believed it if I had not heard it as I was a true sceptic.
Then a few days ago I replaced the fuse in the ps of my exogal comet plus dac/preamp with another sr black and this time not much change. BUT i was then advised to try changing the directionality of the fuse, something again I took with a huge pinch of salt.
WHOA, say what! I simply could not believe the difference this time!

So overall for me I would say the dac/pre had the largest change but only after I had experimented with fuse direction.
So if you bite the bullet be prepared to at least try the idea of changing fuse direction as well.
Good luck and report back with your findings if you go that route.
@mewsickbuff
Replaced the external fuses in my bat power amp with sr black and the internal fuse of my Exogal ps with sr black.
Both instances there was a very profound change. Even more eye opening was that direction of the fuse also made a big difference so do not be afraid to experiment no matter what the nay sayers may state.
My power amp has 4 internal fuses and I will likely replace those as well in the near future
@danvignau 

Have you actually TRIED an aftermarket fuse anywhere in any component in your system?

Hard to be a total naysayer without some first hand experience IMHO
@ps
Welcome to the club!
As you have discovered by your own ears direction does matter
Enjoy
At just $99 I might give one a test drive, heck a lot cheaper than just 1 blue fuse and we know they work.
Besides it is an English company, how could it not work!
Wonder if an SR fuse would have helped on these old bangers?

Talking of Alfas did they not come factory fresh with Vague-lia electronics?
Keep us informed Latik, I am certainly interested if it can perform anywhere near as claimed.
Then we can start a whole new thread!
Looks like the mods took deep offense to our British car tangent...lol
Merry Xmas guys (gals?)!
From previous threads I think most people recommended to go 1 fuse size higher with the SR fuses, not sure quite why though.
That is what I did and 9 months in, no issues....touch wood as soundly raps head!
Big amps have big inrush for sure but surely if fuse rating is correct what difference should it make as to who/what fuse it is if it can handle that inrush?
Even though I can hear sq differences with SR fuses it is a poor show if they do not behave as the rating on them says compared to an el cheapo Bussman fuse for example!

My concern on that would be if i replaced the fuses in a piece that was under factory warranty still with higher rated fuses by SR or similar and then something occurred which caused internal damage to the equipment.
I am not sure how closely manufacturers spec out their fuse ratings for protection...would going from 2.5 to 3a say really make any real world difference internally?
@fleschler 

May I ask?
Did SR reimburse or replace those blown fuses for you?
Or were you hundreds out of pocket on a steep learning curve?

@madavid0

Put up or shut up....
@fleschler 
That is very good to hear!
Good customer service can be hard to find nowadays.
Just bought a Hegel H300 for a second system, think I will order a SR Blue for it and see what I think, manual states 10a.
@ps 
Replacement of main fuses.... Absolutely yes!
I achieved pretty decent sq gains by replacing both mains fuses in my bat VK600SE with sr black fuses. These I kept at stock recommendations for sizing and they have been in there over 9 months now.

Largest sq gain was in my DAC but I think you should be able to hear some improvement.
@shadorne 

Your assertion that a large number of members here own "pieces of crap" is both arrogant and deeply disrespectful
@jetter 

And have those non vocal members tried aftermarket fuses in their obviously"superior" equipment?

Don't get me wrong I used to be one of the largest disbelievers in tweaks and cables....until I ponied up and actually tried them.

Of course maybe it is just a fact that my BAT, Primare and Exogal are "pieces of crap"
Imho the mods are handling this whole forum completely wrong...and yes this may merit deletion as I have found they also do,not like criticism, constructive or otherwise!
Speaking from experience here as a mod on other forums motor related we would not stand for the nonsense spouted by a select few on a regular ongoing basis.
We had a very simple infractions system and when you got too many points it was timeout.
Now the timeout varied by nature of the infractions and repeat offenders.
It was not uncommon for unwanted elements to find themselves on a permanent timeout!
I don't think that would be out of place here as these forums are rapidly going to hell in a handbasket.
Just my 3 cents worth you understand
Guys.....
It is not just what you say but HOW you say it, that is part of the problem
I guarantee that the majority of the name callers and mud slingers would not dare talk that way in real life to the other party without the keyboard and monitor to hide behind.
Yes it is a freedom of speech era for sure but still what defines a civilized world seems to have become very blurred on forums today.
Feel free to have at it of course, all it does is make a big mess of any thread with numerous deleted posts that with replies to said deleted posts makes the thread nonsense at times.
Much more sensible to just strike the offenders.
Maybe it is time for a thread on thoughts on how mods should take action, see what the mindset is.
Whatever let this thread get back to the subject matter at hand and try and cease all the inhouse fighting.
SR Blue Fuse I think it was.........
@mitch2.
Why just take one small phase out of context with the rest of the post? Yes a little aggressive but sometimes you need fight fire with fire....
As you correctly state it used to be with large doses of humour and a smirk.
Now we see increasing amounts of vitriol that is neither wanted or warranted.
But I have started a thread on the matter so let us not clog up this thread....
I would have to agree Wolf that Frank can be a little over zealous in his proclamations...lol.
However I was one of the biggest disbelievers in existence in these type of tweaks.
But I swallowed my ego and gave the SR fuses a try.
And I know what I heard, simple as that.
I also truly believe that some will not hear anything at all for whatever cumulative reasons.
I have no problem also giving the TC a trial as well when it appears to be well proven by time.
Everybody is of course free to post their thoughts and opinions but it does appear to get out of hand at times.

Would not be the first time I have smeared expensive goop on my valuable gear...........
So to put this train wreck of a thread back on track.
Whilst partaking in some light hearted banter I was actually evaluating my very first Blue fuse!
As previous Black fuse experience was all good thought I would go ahead and add one to my new to me Hegel h160 integrated.
This is with only couple hours burn in time mind you.
Dropped the needle on,one of my favorite albums, Growing up the hard way by Mamas Boys, so much energy in the grooves of this album!
After being assaulted by the bass drum from just a few bars in I knew I was in for a great ride.
This album already has great presence and impressive focus of instruments.
But it all is now elevated to a higher level altogether.
Next up Crime of the century by Supertramp.
The piano on the title track truly brought shivers to my spine, especially at not immodest volume levels.
As far as I am concerned $149 very well spent!
I failed to obtain Total Contact so I may need to Tweek my methodology somewhat.
😇
Lmao
The cynicism displayed on this thread never ceases to amuse me.

Yes I agree sometime the plaudits are way over the top but all I know is that in my system both the SR black and blue fuses  made an audible change for the better.
I have not compared black to blue as have not upgraded from one to the other, just have them in different equipment.
Happy listening people.
💿
@mattspl.

 Exactly! I do not totally understand how they work either, but for me they do and that's enough for me.
Conversely I can also see and fully believe they do not work for others. That is why there is a 30 day money back trial.
@slaw
I think Frank has taken the high road and made the hard but ultimately wisest choice to just ignore the ignorami en masse.
I mean when members are still firing off trite and yet openly admit they have NEVER tried a SR Blue fuse in their system then what is the point in arguing any further.....
@a25105.

I think you may find people will hold onto to them like myself as a spare just in case.
Or as Mattspl said and use in a second or third system.
You do see occasional black and even red fuses for sale on eBay now and again.
I have been very happy with the black fuses, with a new amp it is going to be high time to try out a blue fuse in it.
expecting good things only from prior black fuse experience.

George, please just TRY a Blue fuse for once instead of just decrying them all the time. By your own admittance many posts ago you have never actually tried one, unless this has now changed and you are basing your arguements of actual listening experience?

I have found in my audio journey throughout the years that there are PLENTY of things that defy any scientific explanation!
And now we wait for all the science majors to tell us we are wrong and obviously tone deaf......
Way too many people hear a difference even with directionality for it to be snake oil surely even the naysayers must accept that.
People
Do you seriously think that our little audio hobby is the ONLY area in the world where science cannot explain away everything or be followed faithfully?
You really need to get out a bit........
Wolf
I will agree with you that science cannot explain it, you maybe cannot measure it either.
But there is a whole raft of crap  in this world that science cannot explain!
Or if you do not believe that then all of this is falling on deaf ears to be sure.
I have said it before and it seems I have to say it again.
I HAVE NO IDEA WHY FUSES HAVE THE SQ IMPACT THEY DO IN MY SYSTEM BUT THEY DO!
Additionally I truly DO NOT CARE EITHER!

It is not "expectation bias"
I mean $120?
cmon lets get real, that’s peanuts in this hobby!
$10000, maybe I can see people forcing themselves to believe it worked but $120 with a 30 day return policy, no way!
How can you not feel the love for Doc Browns headwear!
Replete with 1.21 jiggawatts!

Back to the future is sometimes pretty apt here.....
Wolf
I have no issue with you at all but.....
$120(at black fuse) is not even pocket change in all honesty so it has zero expectation bias or placebo effect in me whatsoever.

So why do you have to try to insult my intelligence?

I was one of the biggest sceptics on this planet for tweaks etc.
Until I manned up and bought a couple fuses to try as with return policy how can u go wrong?

And I HEAR the difference, end of story.

No placebo
No expectation bias
No BS

you cannot hear a difference and I respect that.
But your seemingly absolute refusal to accept how anybody else possibly can is the real insult here .


No offense.....
Charles
Of course I HOPED for positive results based on all of the feedback in this forum, or as you say, why buy anything?
However I approached with a completely open mind, at least I hope I did.
Absolutely Charles.
I have indeed purchased cables that although I could not say was anything wrong with them but just did not "fit" my system or my sound at all and unfortunately had to return them. Obviously not what I intended upon purchase!
Have not yet stepped up to blue fuse, indeed my present system appears to be devoid of changeable fuses so quite possibly will not be, more is the pity just for my hearing benefit on this cause.
Wolf
Your post removal is pretty fresh, it was there still this morning.
I have no idea who wasted their time reporting your posts, them being removed and making some threads nonsensical is a big beef of mine tbh.

Yes there is call for some posts to be removed for sure, that one was not on the list imho.


Well that is interesting indeed.
My post just above Charles has been edited, presumably by a mod.
I guess is better than being removed but I have never seen one edited by a mod before.
Quite odd.....
George
I hate to say it
But you are bordering on narcistic in your response and attitude?
Do you need a hug?
