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. :-)

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.

I would not say harder necessarily....
Definitely more fun to go Zombie hunting for sure though!


Your ears are your best friends to answer that question tbh.
Try both directions and whichever you prefer the sound of 9 if there is indeed a sq change in your system) is the way they need to be for you.
Good luck and have fun
And watch out for the zombies...….
The answer was the one you had already been provided by SR and confirmed by myself.
Just try both ways and listen.
So glad us idiots have all been illuminated by Shadowcats "professional" opinion.
I mean its not like anybody here using boutique fuses could also possibly have a professional opinion as well is it?
If anybody is considering trying an SR blue fuse or three.

Check out partsconnexion.

They are having a promo right now where when you buy 2 you get the 3rd one free.

Hard to beat deal.
Thx David

I did not have any use for 3 more blue fuses but a new receptacle and one blue fuse I could use
Will be checking that special out as well
David

I already have blue fuses, and a black,no need to be convinced here.

However have not yet upgraded any receptacles so that is why that last offer was of interest.

Now a question for the technical minded.

My Mytek Brooklyn dac has a fuse but I do not run it of 120vac, I have it powered of a 12v iFi power supply.
So is the fuse still in the circuit this way I wonder because if not then no point spending any money on an upgraded fuse at all
Think you are correct Al.

From what information I can clean, the Brooklyn has a slow blow fuse on its psu board of 630ma so right in line with your comments.

When using the dc input protection is afforded by whatever fuse is in the external power supply, for example if using the sbooster it uses a 2a fuse, again right in line .
I will have to investigate my iFi ps now.
I feed all my gear from a CPT 1800.
This is fed from my 20a line on a duplex to my room.
I assume that if I change that duplex to a sr blue I will reap some benefits?
Or is the equicore going to negate that?
Not really up for replacing every receptacle in the rear of the equicore right now!
As have no fancy duplex anywhere I took advantage of the SR September special and ordered a Blue duplex and get a free Blue fuse.
Now not sure as overkeen on paying $285 just for a duplex but with a free fuse at $149 its a bit more palatable.

Will report on perceived sq change once installed. 
Yes we will see
The duplex is the main feed into my music room that feeds the cpt1800.

The blue fuse will be going in the ayre ax7e amp. I already have a blue fuse in my Goldnote ph10 phono stage.

Never investigated my old Pioneer sacd player for an internal line fuse to change, sure there is, but as it is used so infrequent decided not even worth looking.

Mind here is an example of crazy ( in some eyes). My old Pioneer sacd value maybe $120.  Hooked up with Nordost Heimdall ic value $600 ..... Lol.
Received my Blue Duplex along with free Blue fuse today.
Not had time to install duplex yet, plan for tomorrow but did slip the fuse into the Ayre ax7e.

I played exact same album as I had on last night, a piano driven piece.

A lot of difference imho, notes seemed to hang in the air filling out the music more.
Deeper it appears to delve into the actual recording. Hard to really put into words, just seems more fleshed out overall.
Lets see what the duplex brings tomorrow.
Slaw
Yea I thought you was mostly vinyl.
I only asked as prior to this purchase I had bought a blue fuse and placed that in my Goldnote ph10 phono and I thought it made quite a difference.

I think you will be impressed.
Hard to tell what is having the biggest effect as I have so many new tweaks in place right now but all I can say is everything is adding up to lower noise floor considerably.
With my ear up against tweeter on my analog phono stage I can barely hear a faint hiss. Before tweaks it was not terrible but definitely a lot more audible than it is now.

And it should only get better.
I have a blue fuse in both my integrated and my phono stage.
Hard to beat covering both units!
Slaw
This is just the start of that ever progressive "tweaks" spiral

I have ceased spending money on equipment and it has only been tweaks of late like SR Blue fuses, duplex, TC paste, E-Cards etc etc.

Enjoy!

It only gets better
I hear you Slaw.
Likewise on present system sounding good but every tweak I have invested in over last few months after doing a lot of research before spending money, has elevated it a little at a time.
I would say one of most profound results is reduction of background hash, most,noticeable on phono input.
More air around everything and just basically more depth and feel to the music.
And as you rightfully state... It truly all is about the music !
Elizabeth
A little 120v never hurt anybody.
It's as good as a double espresso in the morning to get you ready for work...lol.
Now one leg of 480v.... Ouch that hurts!
Still have all my fingers and toes though,none been burnt off by high voltage yet.
And yes I work with 480v and even 600v line's at work in my real job.
What fuse is used on a Pass X350.5? and where is it located? Thank you
I believe it is a 5a fuse and it should be located directly above the iec power socket in a round twistlock holder.

But you should double check your manual or with Pass themselves

Good luck
Shoot!
My bad, I misread and was looking at the 30.5!
Yes indeed the 350.5 which is a heck of an amp, very nice , uses breaker technology.

Thx for correcting my blunder David.

😔😔😔
I think most that have used aftermarket fuses ( at least SR fuses) have found that they need to use uprated fuses for whatever reason which I do still find rather odd, after all melting point for a 5a load should be the same design whatever the actual wire is made from, or something is not right.
This is one aspect of these fuses I do not like or agree with.
However on the flip side just as NB_Dude stated you can hear a difference so....
I am "currently (sic)" using a SR Blue rated at 6.3a in my Ayre AX7E, stock fuse was 5a. I purchased the 6.3a after reading similar stories here but would it have blown a 5a? Who knows, I do have about 500 hours on the 6.3a fuse and in my case it is an extremely tight fit in the fuseholder in the back of the amp, much more so than the standard glass 5a I removed.

As an aside before I put the SR Blue fuse in I actually spoke with Ayre customer service by telephone regarding a different matter and mentioned the fact I was thinking of going with an aftermarket fuse and what their thoughts were. The guy I was speaking with was completely for swapping out fuses as he believed they made a big SQ difference. Made me want to ask why they did not fit them from the factory but that my be a commercial sales decision not something customer service may want to deal with... lol.
Sorry but I do not get it.
A 5a rating is a 5a rating..... period!

How can a simple glass fuse rated at 5a work in same scenario and yet not a SR Blue rated at 5a?

Dont get me wrong I hear a SQ difference but that part of rating makes NO SENSE at all.

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
Different folks and different strokes.
Herbies tube dampner did nothing for my Audio Research preamp that I could hear.But 4 Shakti Stones are still in use today of which I am sure they have a positive effect.
Go figure......
Ouch.⬆⬆⬆⬆⬆

Someone got of bed the wrong side today......

😲😲😲
Discopants.

From my memory of the tdai, the internal fuse was not of a quick replacement variety and you would need to get creative to swap it out with a SR Blue.
None of the Lyngdorf integrated amps have user replaceable fuses.
Yes they have fuses but you would need to be creative to replace them as not plug and play.
sorlowski.
Nice work and report indeed.
Just the type of feedback required from somebody who cannot be accused of sensationalism or hype for SR products.
Thank you
Well that sucks Mr D.
Sorry for that ruination of a day.
No I cannot say as I have ever seen that style of mounting the main fuse holder before but I am sure someone will have.
The question is, can you solder it back onto the board? Is there enough to work with?
I hope so as a terrible waste otherwise.
Mr. D
I am in north East Florida and I certainly hope you have a better line on competent techs in central Florida than we do up here.
Majority I have run into so far I would not trust with a packet of Gummy Bears.

Good luck with it my friend. 
George subbed his fuses a long time ago with twin 1000a breakers.
Otherwise his ire would have turned to fire.
Just cant help yourself can you George?
Now resorting to hurling direct insults to members just because their posting  goes against your extremely narrow and bigotted viewpoint.
Keep it up, you really are revealing yourself to be a world class act!
